You’ve probably seen peptides popping up in seemingly every product as a universal panacea for all kinds of beauty issues, from fine lines, wrinkles, uneven texture, and dullness. That’s because they work, and even quite well, especially when used in serums, which allow actives to penetrate deeper into the skin due to their small molecules. With this in mind, we rounded up the best peptide serums that will put you in the fast lane for a resilient and youthful complexion. If you’ve been noticing early aging signs, it’s high time to add one to your routine.
What peptides do
As a refresher, peptides are short chains of amino acids that act like building blocks of proteins like collagen, elastin, and keratin. When applied to the skin, they soften the look of fine lines, repair the epidermal barrier, help reverse sun damage and reduce transepidermal water loss, all of which lead to a smooth and plump appearance. Another exciting thing about peptides is that they can penetrate the outer skin layer—they’re called cell messengers for a reason. Sinking into the epidermis, they support cellular functions to repair cells, build proteins such as collagen, and provide access to other ingredients to enter the skin.
Sure, peptides aren’t going to magically make your wrinkles go away—nothing can, anyway—but without them, your skin will be more prone to develop premature aging signs and a dull look. So using a peptide-infused serum as part of your daily routine is one of the best treats you can give your skin to keep it looking and feeling younger.
Who can use peptide serums?
Because they are naturally found in the skin, peptides are gentle and work for everyone, even people with sensitive and acne-prone skin. Unlike some other actives, peptides can also be applied on damaged and sunburned skin and can actually help with the healing process—they can be applied right after chemical peels or microneedling. However, to stay on the safe side, you should perform a patch test before going all in with new products.
Moreover, peptides are versatile and work wonders when paired with ingredients like niacinamide, hyaluronic acid, antioxidants, vitamin C, and retinol. However, don’t mix peptides with alpha-hydroxy acids as, due to the acidic pH of acids, it may reduce peptides’ effectiveness—do the peeling prior to using your peptide serum.
The best peptide serums for anti-aging
Now that you’ve got your background around these anti-aging wonders, scroll on to shop the best peptide serums for all your skincare needs.
Clinical Skin Polypeptide Firming Serum
I’m currently using this, and trust me, it’s worth the first spot on the best peptide serums. It loads a generous amount of peptides, including Matryxyl and copper peptide, all of which boost collagen production for a plumper look and refined texture. Additionally, the formula packs ceramides and cholesterol to strengthen the skin’s natural barrier, while sodium hyaluronate and the active form of vitamin C increase moisture retention. The clinical-grade formula is both preventative and corrective, and it’s as great for protecting the skin from photoaging as it is for increasing firmness and reducing redness. It’s a solid option for pretty much everyone.
