16 best retinol serums and creams for every skin type – tried and tested with pictures

The skincare ingredient that needs no introduction...

By , ,
Jump to Products

Retinol is considered the gold-standard ingredient by dermatologists all over – and for great reason. It’s lauded for its ability to smooth fine lines and wrinkles, improve skin texture, fade pigmentation and prevent acne flare-ups. Not to mention, this hero ingredient will make your overall complexion look brighter, glowier and more unified.

Do we have your attention? Good. Over the past few months, we have been testing over 30 serums – from budget heroes to luxury players – to find the very best retinol formulas depending on skin type and preference. Plus, with the help of a few experts, we have decoded everything there is to know about the skincare ingredient.

The best retinol serums, at a glance

What does retinol do?

So, ‘what is retinol?’ you may ask. Well, as leading Hollywood dermatologist, Dr Lancer, who works with famous faces like Victoria Beckham and Beyonce, explains – it’s one of the most effective skincare ingredients out there.

“Retinol [or vitamin A] is lauded for its medically and scientifically-proven ability to speed up the skin’s cell cycle,” he says. “It is one of the few ingredients on the market that comes with this absolute guarantee – it has no gimmicks.” The zero BS approach makes it even more appealing.

When you get into a consistent routine using retinol, you’ll notice a few transformations happen to your complexion: fine lines start to soften, dark spots fade, and your skin will feel smoother, firmer, and more radiant overall. Now who doesn’t want all of those things?

Below, see our edit of the best retinol serums our editors have tested. There’s one for every budget, skin type and sensitivity level. Plus, keep scrolling to read common FAQs around retinol, answered by Dr Lancer and Dr Hall.

Medik8 Crystal Retinal Stable Retinal Night Serum

Pros

  • The product comes in different retinol grades – meaning everyone from those with sensitive skin to advanced users are able to use
  • Built-in hyaluronic acid and vitamin E plumps and hydrates skin

Cons

  • Can be thick and take a while to absorb into skin

Why we love it: You’ve heard of retinol, but have you tried retinal? This clever crystal-encapsulated retinaldehyde formula works faster than normal retinol, thanks to its ability to be easily converted into retinoic acid by the skin. It also causes less irritation and comes with built-in hyaluronic acid and vitamin E to plump and hydrate your complexion.

What sets Medik8’s retinal apart from the rest is that it’s available in a range of strengths, from one to 10. If you’re a new starter, begin at number one – as the lowest strength, this is a great beginner formula to ease you in slowly. Number three is our go-to for medium strength that packs a punch with no irritations. Once you’ve graduated from that, you can keep working your way up the retinol ladder. After use, you’ll quickly discover how well this stuff works: in a matter of weeks it fades discolouration, brightens and smooths texture.

Glowing customer review: "A lovely textured cream with a pleasant smell. Started with a sample size and built up to a full size product to check that my usually sensitive skin could cope. So far so good! My skin looks less dull and have received comments that my face tone is brighter. I like how the website gives you a clear step by step guide of how to layer with other products to ensure you maximise their efficiency through their science. Smart looking packaging makes a classy statement on the bathroom shelf too."

The Inkey List Starter Retinol Serum

Pros

  • It gently smooths fine lines, texture and discolouration without irritation
  • It feels nourishing and soothing on the skin
  • It’s affordable

Cons

  • Those after something stronger should try The Inkey List’s Advanced 0.2% Retinal Serum

Why we love it: The Inkey List’s new Starter Retinol Serum is for, as you’d assume, those just starting out with the ingredient. It’s designed to smooth fine lines and improve skin texture, all the while keeping the skin feeling nourished and free from irritation.

Clare Stephenson, Cosmo’s Senior Fashion and Beauty Ecommerce Writer, says: “I think this is a brilliant formula for complete newbies. It’s formulated with a slow-released, encapsulated, dual-retinoid complex which essentially means it steadily exposes your skin cells to retinol rather than loading it on. This helps to prevent adverse side effects. Then there’s a 0.2% Symrelief 100 (an anti-irritant) to keep the skin hydrated and soothed. I’ve been using it every night without trouble: it works well with the rest of my skincare routine and not once has my complexion felt sore or irritated.”

Glowing customer review: “Beautiful lightweight serum. Easy to apply and has a yellow colour. Perfect for users who haven’t tried a retinol serum before. Gives you wonderfully soft skin.”

Pros

  • The serum is formulated by dermatologists
  • Niacinamide and ceramides provide anti-inflammatory properties
  • It’s budget friendly

Cons

  • Experienced users may find the potency too low

Why we love it: If you’re a retinol novice, worry no more, for this serum is a great way to ease yourself in. Developed with dermatologists, the CeraVe Resurfacing Retinol is a gentle yet effective way to reduce the appearance of acne marks and visible pores. Alongside retinol, it also includes CeraVe’s hero ingredient: ceramides.

See ceramides as like the glue that holds your skin together: they keep your skin barrier healthy and strong – sealing moisture in and keeping pollutants out. Refined skin without compromising its protective barrier? Win-win.

Glowing customer review: "After consistently using the CeraVe Resurfacing Retinol Serum, I noticed a visible improvement in my skin’s texture and tone. My skin appeared smoother, and some of the post-acne marks began to fade. The serum did not cause the intense irritation that can often accompany retinol, which is a significant plus for those with sensitive skin. I recommend starting with 2-3 times a week to allow your skin to acclimate, gradually increasing as your skin builds tolerance."

Pros

  • It’s gentle enough so that it can be used every day
  • It’s packed with hyaluronic acid and squalane to keep the skin hydrated

Cons

  • It's expensive

Why we love it: A powerhouse anti-ageing serum that blends retinal (11 times more effective than retinol) with hyaluronic acid and squalane, to smooth the skin without having to worry about all the irritation that usually goes hand in hand with a strong retinoid.

Cosmo’s Senior Beauty and Fashion Ecommerce Writer, Clare Stephenson, is a particular fan: “As a fairly new user to retinol (hi, hello, I’m 26), this has eased me in without the harsh side effects. When I was testing it for this feature, I used it – near enough – every day and it felt comfortable on my skin, mixed well with the rest of my skincare routine and I saw results after only a few weeks. I noticed my complexion looked smoother and glossier – and post-acne scars faded too.”

Glowing customer review: "I was hesitant to order, as I never used retinol before and have sensitive skin to acids. This product is literally the best skincare I ever had. It transformed my skin! The texture is smoother and more even now. No irritation at all, no redness just PERFECT!"

SkinCeuticals Retinol 0.3 Corrective Treatment for Mature Skin

Pros

  • It contains 0.3% pure retinol, so it’s strong enough to see results without causing irritation
  • It also contains soothing ingredients, like chamomile and boswellia serrata extract
  • It’s fragrance free

Cons

  • It’s a very expensive formula
  • Those with sensitive skin may notice some initial irritation

Why we love it: Pure retinol (not derivatives!) makes for SkinCeuticals' 0.3% formula – don't get it twisted. So, with that in mind, you can expect a stronger promotion in cell turnover, which diminishes the appearance of fine lines, wrinkles, uneven skin tone and blemishes. Y'know, all that good stuff.

The best way to use this potent formula is as a targeted treatment. Only apply it to the areas you need it most (read: fine lines, pigmentation etc) – and luckily so as, with a £90 price tag, you don’t want to be wasting this stuff. Just be sure to use it sparingly and respectfully.

Glowing customer review: "This is my first SkinCeuticals Retinol and I do not regret buying it. It is an expensive product but lived up to the hype. Though I have only been using it for a week, I see difference in my combination skin. There was a bit of redness for the first two days but it went away fast. My skin is brighter and more even-looking. I will definitely be repurchasing it. Wish we get to buy the 0.5% version here as well."

Pros

  • Gentle and beginner-friendly retinol
  • Affordable skincare for mature skin
  • Non-comedogenic and fragrance free

Cons

  • It’s a gentle formula, so results are slower

Why we love it: Listen up, if you’re new to retinol, on a budget and want to prioritise softening fine lines and wrinkles, this is the formula for you.

CeraVe’s serum combines retinol with ceramides, hyaluronic acid and niacinamide to not only target fine lines but to also support hydration and the skin barrier. The texture makes it genuinely enjoyable to apply too: it has a milky consistency that feels light and refreshing, which is exactly what you want in your evening skincare routine.

Glowing customer review: “After consistent use, my skin started to look brighter, smoother, and more refined. The serum helped soften small lines and gave my face a healthier, more even appearance. Another great point is that it doesn’t cause the harsh dryness that many retinol products do.”

Best budget retinal serum

The Ordinary Retinal 0.2 Emulsion

Pros

  • Super affordable
  • Retinal formula works quicker for more noticeable results
  • Great for reducing dark spots

Cons

  • The yellow tint can leave a mark if not removed from clothing straight away

Why we love it: Use this after cleansing at nighttime (never during the day as sun exposure will render it ineffective) and if you're patient (and consistent!) you will see results... we promise.

Not all retinoid formulas are made equally, but retinal is more effective and will work more quickly than retinol (it's confusing, we know), but most products that use it tend to be quite expensive. Well, that’s not the case with The Ordinary. They came along with its Retinal 0.2% Emulsion, which comes in at a pocket-friendly £15.20. Though the formula may look intimidating (a heads up, it‘s vibrant yellow), it’s a very tolerable formula that gently smooths your skin tone, fades pigmentation and promotes a brighter complexion.

Read our full review of the product, here.

Glowing customer review: "The Ordinary’s Retinal 0.2% is great and when I use is the last serum in my routine before my face cream. Great value for money and seems to be helping with reducing dark spots. I would recommend!"

Murad Retinol Youth Renewal Oil Drops

Pros

  • Oil formula moisturises skin
  • Results in as little as two weeks

Cons

  • If you have super oily skin, you might not like this formula

Why we love it: Super dry skin, but still in need of a retinol? Look no further than Murad's Retinol Youth Renewal Oil Drops. We get it even those with skin drier than the Sahara desert sometimes don’t like the feeling of a heavy oil, but this formula is super lightweight yet ultra nourishing – a few drops is all you need to feel moisturised, never greasy. Alongside retinol, the formula also contains omega-6 fatty acids to reduce fine lines and wrinkles, boost moisture and improve elasticity.

Better yet if you don’t want to apply the oil directly to your face, you can also mix a few drops into your daily moisturiser – just make sure it’s a formula without any added actives. Not only will this make the retinol slightly gentler (which is especially useful if you have dry, sensitive skin) but it will make your money stretch further too.

Glowing customer review: "Since starting it I've noticed less redness and more hydrated skin. I love the Retinol Oil because a little goes a long way - it both lasts a long time and I've seen actual change from this product. It is easy to use and my skin is sensitive and this wasn't irritating at all."

The INKEY List Retinol Serum

Pros

  • Beginner-friendly: The 1% slow-release formula is designed for those new to retinol, minimising potential irritation.
  • Super affordable
  • Vegan and cruelty free

Cons

  • Not strong enough for advanced users

Why we love it: As you may have gathered, retinol can be pretty pricey. But fear not for The Inkey List, one of our fave no-fuss cult brands, is here to save your day skin.

At just £14, this hero is no less than in comparison to its counterparts. With 1% retinol acetate, 0.5% granactive retinoid and squalane for hydration and soothing, we're hitting a home run in everything anti-ageing.

Just use a pea-sized amount 1-2 days a week (to begin with) and see fine lines, wrinkles, hyperpigmentation and uneven skin tone diminish. The packaging may not look particularly exciting, but it’s what’s on the inside that counts.

Glowing customer review: "I have used a lot of Retinols but this one feels different. I follow a dermatologist and she swears by it decided to try and couldn't agree more. The product's colour, smell, texture itself shows it has great ingredients also the price is too good for the product quality"

No7 Pure Retinol 1% Retinol Night Concentrate

Pros

  • It contains 1% pure retinol to target fine lines and wrinkles
  • It has a slow-release oil encapsulation system, so it delivers retinol gently to your skin
  • It’s a budget option

Cons

  • It takes consistent use to see results

Why we love it: This cult night cream is one to consider if you steer clear of retinol due to skin sensitivity. Scientists behind No7’s Pure Retinol 1% Retinol Night Concentrate carried out extensive research into the retinol “sweet spot” (maximum concentration meets minimal irritation), and added bisabolol (found in Chamomile) to calm and soothe. The anti-ageing formula is also boosted by No7’s go-to peptide blend, Matrixyl 3000 Plus.

Glowing customer review: "I would highly recommend this product. It really does improve your skin. I am 73 and my skin looks really less wrinkled. Like all products you have to keep using it and gradually you can really see a difference."

Elizabeth Arden Retinol + HPR Ceramide Capsules Rapid Skin Renewing Serum

Pros

  • The air-tight pods keep the formula potent
  • Ceramides keep the skin hydrated and plump
  • Travel-friendly

Cons

  • It’s not a fragrance-free option

Why we love it: Two wrinkle-busting power players sealed in serum capsules, these are a dream if you're always on the go. Single-use air-tight pods preserve the potency, making it 76% stronger than unencapsulated retinol, while hydrating ceramides prevent the dreaded dryness that often accompanies retinol.

Clare Stephenson, Cosmo’s Senior Fashion and Beauty Writer, says: “One of the things I find most frustrating with skincare is knowing the right amount of product to apply. I find myself slathering on a serum that only needs two drops, or applying not enough moisturiser than the recommended amount. What I love about these capsules is it’s the perfect dose: you twist off the top, squeeze out the formula and apply.”

Glowing customer review: "The capsules feel super luxe and make it easy to use the right amount. My skin feels smoother and more hydrated without irritation. Absorbs quickly and doesn’t feel greasy. No strong scent either, which I appreciate. Too soon to see major changes, but so far I’m loving the texture and hydration boost."

Pros

  • Can be used during the day time as well as night
  • It also contains peptides and ceramides to keep the skin hydrated and plump

Cons

  • It’s an expensive formula

Why we love it: Despite containing a potent hit of retinol, this clever serum also contains peptides and ceramides. Which means what, exactly? Sensitive and dry skin users, we’re looking at you. Thanks to these nourishing ingredients, you can comfortably use this hard-working formula and it won’t cause dryness, redness irritation. That’s why it’s called the Daily Micro-Dose Serum: you can use it daily, without any troubles.

As for the price tag, *gulp*. We know, it’s a spenny formula but it does a stellar job at gently promoting your skin’s natural renewal process, thus helping to fade pigmentation and texture. Stay loyal to it and you’ll understand the £75 price tag.

Glowing customer review: "Been using this for nearly a month. Good introduction to retinol. I like the pump gives you correct dose to use and a little goes along way. Looking forward to see the results after longer use."

Best collagen boosting retinol

Beauty Pie Super Retinol Serum

Pros

  • It contains ceramides and retinol to support the skin barrier and prevent dryness
  • The retinol is encapsulated, so you’re less likely to experience irritation
  • It’s fragrance free

Cons

  • It’s a powerful serum, so take it easy if you’re new to retinoids

Member price: £23

Why we love it: Is there anything Beauty Pie can't do? This retinol serum is one of our all-time favourites due to its super-smart formula. It uses an encapsulated retinol complex, which basically means the serum is absorbed by the skin before releasing, meaning you get maximum efficacy, without the dreaded irritation.

The Super Retinol Ceramide-Boost Anti-ageing Face Serum has a 3% encapsulated retinol complex, which works on the skin at 0.09% pure retinol. So you can expect some pretty punchy results when it comes to unclogging your pores, boosting collagen production and smoothing out the complexion.

Glowing customer review: "The fact that I am a repeat customer tells you everything. This tube of magic is the business. I have such a high level of confidence that this works as a result of my experience of using religiously every night. I’m holding back the tide with this magic serum."

NIP+FAB Retinol Fix Concentrate Extreme 10%

Pros

  • It's slow releasing so it is gentle on the skin
  • It's affordable

Cons

  • Those with sensitive skin may find the potency too strong, despite it being slow-releasing

Why we love it: This encapsulated retinol (meaning it's time-releasing) formula contains 0.3% pure retinol, so it is not one to be played with. Rather than reacting with your skin cells on the surface, encapsulated retinol protects the molecule as it delivers the ingredient deeper into your skin, and then very slowly releases it. This prevents adverse reactions from happening (think: irritation and redness).

Alongside retinol, it also blends hyaluronic acid and bisabolol (an antioxidant known for its skin-soothing powers) to nurture your skin barrier as it gets to work to help minimise any irritation. It’s a quick worker too: for the impatient, this claims to reduce crow's feet in just four weeks. Not too shabby.

Glowing customer review: "Love this gentle on the skin, only been using for a couple of weeks and my skin is already looking better."

L'Oreal Paris Revitalift Laser Pure Retinol Deep Anti-Wrinkle Night Serum

Pros

  • It contains a decent percentage of retinol to smooth discolouration and fine lines
  • The milky texture keeps the skin plump and hydrated
  • It’s a budget option

Cons

  • Some may not like the slightly floral aroma

Why we love it: This budget serum has received hundreds of five star reviews, and all for brilliant reasons. It contains an impressively potent dose of 0.2% pure retinol, but it’s also formulated with hyaluronic acid to keep the skin hydrated and plump, therefore mitigating any drying side effects.

It also has a milky texture to it, so it easily absorbs into your skin leaving it feeling hydrated and soothed without any irritation during our testing process. If you’re new to retinol or want to tip your toe in without spending a lot of money, we think this is a brilliant place to start.

Olay Retinol 24 Night Serum

Pros

  • Lightweight serum formula
  • The formula is fragrance-free

Cons

  • The potency of retinol isn’t disclosed, which suggests it could be low

Why we love it: Olay’s Retinol 24 Night Serum is one of the best retinol serums we've discovered — and lucky for us, it won't break the bank. Yep, this budget bottle is packed with a potent retinoid complex and vitamin B3 (niacinamide), allowing it to smooth fine lines, reduce skin texture, improve brightness and fade dark spots.

The formula is also incredibly hydrating and fragrance-free, so expect to see an instant improvement as the skin gets a serious moisture hit. As for you sensitive souls, you have the green light to go ahead with this formula. But, as always, go slow and steady to begin with.

Glowing customer review: "I've been buying this for over a year now. Absolutely love it .and it really does make a difference to my skin. I was paying over £30 for it at Boots .Then I saw it half the price on Amazon .I did have my doubts as to whether it was genuine but believe me it is and I would buy it anywhere else now .I'm delighted"

How do you use retinol?

The frequency at which you use retinol depends on the strength of the formula and your skin’s tolerance. “If you’re new to the ingredient, retinol should be started at low concentrations and applied only once a week, building up slowly to nightly or alternative night treatments,” says GP, Pharmacist and Aesthetic Doctor, Dr. Christine Hall.

The key word here being ‘night’. As some retinoids inactivate when exposed to UV light, they are best used as part of your evening skincare routine on clean, dry skin. It’s then advised to follow up with a nourishing moisturiser to ensure the skin stays hydrated.

best cleansing balms

What strength of retinol do you need?

There are variations of retinol and also different strengths. If you're just starting out, you should be using a low percentage. La Roche-Posay Redermic [R] is the perfect starting point as it contains a mere 0.3%, so, it's also a good option for people with sensitive skin. The Ordinary Granactive Retinoid 2% in Squalane is a great contender for newbies, too, plus it's super affordable.

If you're a seasoned retinol user, Medik8 Crystal Retinal is a great option (and one we personally swear by as it is available in a variety of strengths). One of the strongest formulas out there, aka Sunday Riley's A+ High-Dose Retinoid Serum is an incredibly potent, supercharged serum that will get you results fast.

An additional consideration to think about is what form of vitamin A you are using, or how many conversion steps it takes to become retinoic acid (i.e, the purest form of vitamin A and therefore the most effective).

First you have retinyl esters which is the weakest and most gentle form often used in beginner formulas. Then retinol, the most common over-the-counter formula, requires two conversions before activating, so it’s effective and well tolerated. Retinaldehyde sits just one step from retinoic acid, meaning it is strong but more likely to cause irritation. Finally, you have tretinoin (available via prescription) which acts immediately without conversion and is the most powerful.

When should you start using retinol?

In theory, you could start using retinol in your mid to late 20s. This is when collagen in the skin starts to deplete (due to age, sugar consumption, pollution and other factors).

Retinol works by promoting skin cell turnover, boosting collagen production, and reducing the appearance of fine lines, wrinkles, and uneven skin tone. So, prevention is better than cure – meaning, the earlier the better – but obviously, within reason (if you're under 25, you probs don't need it).

If you’re new to using retinol, it is important to know that wearing SPF daily is crucial. “I recommend applying a broad-spectrum sunscreen with an SPF 50 every morning, regardless of weather conditions, to protect the skin and maintain long-term results,” says Dr. Hall.

She explains because “retinol accelerates skin renewal so it leaves newly formed skin cells more vulnerable to ultraviolet damage. Without adequate protection, this may lead to increased sensitivity and pigmentation.”

best cleansing balms

How long does retinol take to see results?

According to Dr Hall, patience and consistency is key – and there is a reason for it.

“Biologically, skin cell turnover takes around 28 days in younger adults and tends to slow as we age. With consistent use, many people begin to notice smoother skin texture and a subtle radiance after four to six weeks. By eight to twelve weeks, improvements in fine lines, uneven pigmentation, and overall skin tone typically become more apparent. More significant collagen stimulation and long-term changes can take three to six months,” says Dr Hall.

When using retinol for the first time, Dr Hall says it’s important to be aware of the ‘retinisation’ phase. “At the start individuals may experience dryness, mild peeling or breakouts. This is usually temporary and reflects the skin adjusting to increased cellular turnover.”

Through her work, she has interviewed leading dermatologists, makeup artists and industry experts to bring readers trusted advice and product recommendations.
Clare has contributed to titles across the Hearst UK portfolio, including Women’s Health, Good Housekeeping, Red and Prima. Prior to joining Hearst, she earned a BA in Multimedia Journalism from Bournemouth University, focusing her studies on magazines and editorial. She later worked as an editorial assistant at Voir Fashion Magazine, covering events including Fashion Week and interviewing notable brand founders.
Outside of work? You can find Clare strolling through London’s Columbia Road Market, pouring her fourth coffee of the day or heading to a Pilates class.
