Peptides are short chains of amino acids, which are the building blocks of protein. Peptides are responsible for ‘signaling’ or communication in the skin. As skin ages there’s a decline in the amount of peptides in the skin.
Peptides in cosmeceutical products aid in tissue repair by stimulating fibroblasts to produce collagen. They have antioxidant properties and help keep skin moisturised. They therefore improve the appearance of wrinkles and uneven texture, and increase the skin’s elasticity.
