What Are Peptides?
Short chains of amino acids, peptides are a building block of protein (a strengthener for the skin) that act as messengers to the cells within it, reminding it to repair, renew and protect itself. Small in size, when added to skincare products, they’re effective at penetrating down into the layers where it really matters.
What Do They Do?
SL beauty contributer Alex Steinherr explains: “Peptides tell the skin to do what it already knows how to do, just better i.e. make more collagen, repair itself more efficiently, calm inflammation and strengthen the barrier. They work with skin biology rather than trying to override it.” This shows up on the surface as reduced fine lines and wrinkles, improved firmness, reduced redness, less pigmentation and breakouts and de-sensitised skin. They’re great for use around the eyes too, especially for those who can’t easily tolerate retinol, as they’re non-irritating.
