Skin & regenerative-biology peptides, explained

Skin questions tend to be practical: ageing, wound healing, pigmentation, inflammatory conditions. They also tend to be where cosmetic marketing and clinical research blur together. The peptides below range from topical cosmetic ingredients with reasonable evidence to injectable research compounds with serious safety questions.

GHK-Cu (copper peptide) has decades of research in wound healing and skin remodelling, much of it topical and some of it human. KPV is studied for anti-inflammatory effects, mainly preclinically. LL-37 is a naturally occurring antimicrobial peptide studied in wound and infection research. Melanotan II is a different case: it is studied for pigmentation, is not approved anywhere, and has documented safety concerns that a provider will raise first.

The intake asks about skin conditions, sun exposure, mole history, medications and allergies. A licensed provider reviews it and tells you whether any research context here is relevant — or whether dermatology is the better door. Free, about 10 minutes, no obligation.
