Peptides are one element that totally worth the hype! Using a serum that contains peptides can help make your skin look firmer, hydrated younger, with fewer breakouts, can repair damaged skin, even out skin tone, and ease inflammation. A promising skincare ingredient, it seems that everybody needs peptides in their skincare routine.
For starters: what peptides do
First, some background. Naturally occurring in the skin, peptides are required for making proteins in our skin, helping to keep a better skin condition and play a key role in all manner of biological activity. In skincare products, peptides can come from natural sources (plants, fish, eggs), but they can also be created synthetically. There’s a bunch of peptides, all with different powers. 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 or collagen.
Peptides act as building blocks of proteins, having a role in supporting your skin to stay firm, soothed, and hydrated. They penetrate deeply into the skin, providing access to other ingredients. When two amino acids are joined by a single bond, it’s called a dipeptide. Three linked amino acids form a tripeptide, followed by tetrapeptides, and so on; you got it. Peptides can typically contain 50 or fewer amino acids. Simply put, peptides are amino acids that make up some proteins needed by the skin, such as collagen, elastin, and keratin. Peptides can even control factors that contribute to skin sensitivity, tone, and hormonal activity (acne). No doubt, peptides are highly beneficial for all skin types.
The exciting thing about peptides is that they can penetrate the outer skin layer — they’re called messengers for the other skin cells for some reason. Sinking deep into the skin layer, they naturally support key cellular functions to build or repair skin cells.
Despite their formulations’ complexity, peptides won’t produce any irritation, inflammations, or allergic reactions. Actually, they work wonders when paired with a few active ingredients without losing their potencies, such as niacinamide, hyaluronic acid, antioxidants, vitamin C, and retinol. At the same time, I wouldn’t recommend peptides with AHAs (due to the acidic pH) — do the peeling prior to using your peptide serum.
