Palmitoyl Hexapeptide-12 Acetate (Palmitoyl Hexapeptide-12 Acetate (171263-26-6 Free base)) can promote collagen, elastin, and hyaluronic acid on proliferation. It can be used to improve the skin's water content, increase the thickness of the dermis, reduce microgrooves.

Myristoyl Tetrapeptide-12 Acetate (Myristoyl Tetrapeptide-12 Acetate (959610-24-3 Free base)) , the reaction product of myristic acid and Tetrapeptide-12, is a peptide stimulating hair and eyelash growth and enhancing the appearance of eyelashes and/or eyebrows. Myristoyl tetrapeptide-12 can increase keratinocyte proliferation improve appearance, firmness elasticity, and skin thickness.

KLD-12, a 12-residue self-assembling peptide, displays properties that promote chondrogenic differentiation of bone marrow stromal cells (BMSCs). Moreover, KLD-12 hydrogel can effectively fill full-thickness osteochondral defects in their original location, leading to improved cartilage repair.

Tiger17, a cyclic peptide derivative of tigerinin-RC1 and tigerinin-RC2—antimicrobial peptides from the crab-eating frog (F. cancrivora) skin secretions—enhances HaCaT keratinocytes and human skin fibroblasts proliferation at 5 to 20 µg/ml concentrations, and promotes HaCaT cell migration at 20 µg/ml. Additionally, Tiger17 augments RAW 264.7 macrophages' recruitment and secretion of TGF-β1 and IL-6. When topically applied at 20 µg/ml, it accelerates wound closure and re-epithelialization in a mouse model of full-thickness dermal wounds.
