Ingredients

Peptides signal the skin to produce more collagen through its own natural repair pathways. This focused formula puts all its power behind one proven active for maximum impact.

Peptides are short chains of amino acids that act as chemical messengers inside the skin. When applied topically, they mimic the signals that trigger collagen synthesis, essentially nudging the skin into repair mode. Unlike retinol, which forces cellular turnover (and can irritate), peptides work through the skin's own natural pathways, making them particularly effective for daily use without downtime or sensitivity.
