Acetyl Tetrapeptide-5 is a synthetic peptide used in cosmetics primarily to reduce periorbital puffiness and improve skin elasticity by inhibiting angiotensin-converting enzyme activity and reducing fluid accumulation and glycation. It is commonly found in eye creams and anti-aging formulations.
Palmitoyl Tripeptide-1 is a synthetic palmitoylated peptide (sequence Gly-His-Lys) used in cosmetics to signal fibroblasts and support collagen and extracellular matrix synthesis. It is commonly combined with other peptides in anti-aging and firming formulations.
