Applications by claim category
Cosmetic peptides are not one ingredient class — they work through distinct mechanisms, and each supports a different claim arm. Here is how the four actives map to the claim category a brief specifies.
Ferry a trace element — copper — into skin, where the element is the functional payload. Support repair, renewal, and scalp/hair claims.
Signal dermal fibroblasts to support collagen and matrix proteins. Support firmness and fine-line claims that develop over weeks.
Actives
Soften dynamic expression lines through the neurotransmitter-release pathway — the topical, far gentler cosmetic analogue of injectable expression-line treatment.
