Ingredient Info

Palmitoyl Tripeptide-1 (PT-1) is a peptide derived from amino acids that signals skin cells to boost collagen production. Research suggests it works particularly well when applied at night, aligning with your skin's natural repair cycle to support firmness and skin structure.



Benefits

  • May promote collagen synthesis, particularly when applied at nighttime
  • Could improve skin firmness and reduce the appearance of fine lines
  • May enhance overall skin luminance and quality when used as part of a consistent routine

Science: A 2026 clinical trial (n=30) found that nightly PT-1 application synergistically improved collagen metabolism when combined with daytime baicalin, showing significant improvements in skin luminance (+16.29%), nasolabial fold depth (-36.35%), and firmness (+24.35%) over 8 weeks. The ingredient appears to work by boosting collagen synthesis during the skin's natural nighttime repair phase.
