Peptides totally worth the hype! Using a peptide-infused serum can help make your skin look firmer, hydrated, with fewer breakouts, can repair damaged skin, even out skin tone, and ease inflammation. Peptides are serious multitaskers, and a promising skincare ingredient, that everybody needs in their skincare routine.
For starters: what peptides do
First, some background. Naturally occurring in the body, peptides are short chains of amino acids that make up proteins needed by the skin such as collagen, elastin, and keratin. In skincare products, peptides can come from natural sources (plants, fish, eggs), but they can also be created synthetically. Simply put, peptides act as building blocks of proteins, having a key role in supporting your skin to stay firm, soothed, and hydrated. A few linked amino acids are called oligopeptides, longer chains include between 20-50 amino acids, and are called polypeptides, while peptides with two, three, and four amino acids are called dipeptides, tripeptides, and tetrapeptides. Each type of peptide is designed to take care of different skincare tasks, like improving hydration or skin tone, firming skin, or even creating new fibroblasts and collagen.
The exciting thing about peptides is that they can penetrate the outer skin layer — they’re called messengers for the other skin cells for a reason. Sinking deep into the skin layer, they naturally support cellular functions to build or repair skin cells and provide access to other ingredients. Peptides can even control factors that contribute to skin sensitivity, tone, and hormonal activity (acne).
Who can use peptide serums?
No doubt, peptides are beneficial for all skin types. Despite their formulations’ complexity, peptides won’t produce any irritation, inflammations, or allergic reactions. Peptides work wonders when paired with ingredients like niacinamide, hyaluronic acid, antioxidants, vitamin C, and retinol. Btw, don’t use peptides with AHAs (due to the acidic pH) — do the peeling prior to using your peptide serum.
