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 smooth, resilient, and firm skin.

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 — all of which give skin structure, density, and bounciness. Depending on the chain’s chemical structure, peptides can take many forms, yet most of them share the same goal of spurring collagen growth and preserving existing collagen, which in turn increases firmness, elasticity, and moisture retention.

Simply put, peptides soften the look of fine lines, repair the barrier, help reverse sun damage and prevent transepidermal water loss, leading to smooth skin and a 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 skin cells, build proteins such as collagen and elastin, and provide access to other ingredients to enter the skin.

Who can use peptide serums?

Because they are naturally found in the skin, peptides are gentle and work for everyone, even people with sensitive skin. However, to stay on the safe side, you should perform a patch test before going all in with new products.

Peptides work wonders when paired with ingredients like niacinamidehyaluronic acidantioxidantsvitamin 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.

Clinical Skin PolyPeptide Firming Serum

Clinical Skin Polypeptide Firming Serum

I’m currently using this, and trust me, it’s worth the first spot on the best peptide serums because it loads a generous amount of peptides, including Matryxyl and copper peptide, all of which boost collagen production for a plumper look, refined texture, and increased firmness. Additionally, the formula packs ceramides and cholesterol needed for resilient skin, while sodium hyaluronate and the pure form of vitamin C increase moisture retention. It’s both preventative and corrective while also helping defend against oxidative stress, making it a solid option for pretty much everyone.
