How it works in skincare

In cosmetics, firming peptides work by signalling to skin cells to support natural collagen and elastin production, helping to improve the appearance of firmness and elasticity. They are commonly added to targeted serums, eye creams and moisturisers where they sit on the skin’s surface or penetrate the upper layers to visibly smooth fine lines and enhance overall skin resilience.
