Tetrapeptide-3 is a short signal peptide designed to support skin structural proteins and improve the appearance of aging skin.

By helping to promote collagen and extracellular matrix components, it can contribute to enhanced firmness, elasticity, and smoother skin texture over time.

It is suitable for use in anti-aging serums, creams, neck and décolleté treatments, and eye contour formulas, especially in products positioned for skin restructuring and wrinkle reduction.

Tetrapeptide-3 is compatible with typical oil-in-water emulsions, gels, and serum systems and can be combined with other peptides, hyaluronic acid, and antioxidants for synergistic effects.
