Diaminopropionoyl Tripeptide-33  is a synthetic peptide widely used in cosmetic formulations for anti-aging and skin-firming effects. It consists of a tripeptide (three amino acids) conjugated with diaminopropionic acid, which enhances peptide stability, skin penetration, and bioactivity.
This peptide is known for its ability to stimulate collagen and extracellular matrix protein production, helping to reduce the appearance of wrinkles, improve skin elasticity, and enhance firmness. It is commonly incorporated in face, neck, eye, and décolleté treatments.
