Mechanism of Action
Acting as a fragment of the wound healing peptide HB-107, Heptapeptide-7 operates on multiple levels within the skin. It stimulates the proliferation and migration of keratinocytes, which are crucial for epidermal renewal, and directly induces collagen synthesis. Microarray analysis confirms its ability to up-regulate genes involved in cell division, growth factors, and extracellular matrix (ECM) components within dermal keratinocytes. This peptide also fosters ECM remodeling by encouraging fibroblasts to produce collagen and elastin. Additionally, it exhibits Epidermal Growth Factor-like (EGF-like) activity, aiding in wound healing, barrier repair, and overall skin protection.
