As a beauty editor who's borderline obsessive about skincare, I couldn’t believe my eyes when I saw that Dr. Diamond’s Metacine products are now available on Amazon. And as if that wasn’t exciting enough, the luxe InstaFacial line is currently 20 percent off for Prime Day (aka right now). It's probably the best deal I've seen so far, and I *will* be stocking up on my favorite anti-aging skincare, which is loaded with collagen-boosting and radiance-inducing ingredients. If you’re not already familiar with the Beverly Hills plastic surgeon’s products, let me take the opportunity to introduce you.
Inspired by Dr. Diamond’s celeb-favorite InstaFacial, which is performed in his office, the formulas bring a skin-smoothing treatment to your own bathroom sink. My personal favorite of the three products is the Plasma Bioactive Growth Factor Serum. The powerhouse ingredient list combines five different growth factors that mimic those found in PRP (platelet-rich plasma, a treatment that uses your own blood to stimulate skin healing and rejuvenation). It’s also loaded with a blend of peptides—including a copper peptide to strengthen and repair the skin barrier and a “Botox”-esque peptide to reduce the look of fine lines—that boost collagen and elastin, fade dark spots, and smooth the skin for a firmer, lifted, and more radiant complexion.
And look, I know $200 is pricey for a skincare product, but I've rarely seen the bottle on sale. Saving $40 is a pretty sweet deal, and the results of these anti-aging skincare heroes are nothing short of incredible.
No matter your skin type, this formula is powerful enough to prolong and tackle fine lines and wrinkles, yet gentle enough that it won’t irritate sensitive skin. As someone with acne-prone and super dry skin, I love using it daily as a preventative treatment since it's non-comedogenic and also super hydrating. The texture is lightweight, layers beautifully under my other skincare steps, and it doesn’t interfere with my makeup.
The rest of the brand’s InstaFacial lineup includes a collagen serum and a retinol-packed night cream, both of which are also marked down for Prime Day.
Cosmo's beauty director Lauren Balsamo is also a major fan of the brand. “So many anti-aging formulas end up breaking me out, but my oily, acne-prone skin loves Metacine." She explains that "the plasma serum feels water-light and really helps with my skin tone and texture, and the nightly retinol cream is excellent for keeping my skin smooth and pores clear.”
With 20% off the entire Dr. Diamond Metacine InstaFacial line, there’s no better time than the present to shop these rare discounts. Whether you’re looking to address uneven tone, smooth fine lines, or keep your complexion firm and glowing, this luxe skincare is one of the few that are actually worth the splurge.
