Research
Studies & key findings
- Palmitoyl-KTTKS (Pal-KTTKS) functions as a matrikine — a collagen-derived signaling fragment that activates TGF-β receptors on dermal fibroblasts, stimulating dose-dependent synthesis of collagen types I, III, and IV, fibronectin, and glucosaminoglycans without the irritation profile of retinoids.
- A 12-week, double-blind, placebo-controlled split-face study in 93 women found 3 ppm Pal-KTTKS in moisturizer produced significant improvements in wrinkle depth and fine lines versus placebo on both quantitative imaging and expert grader assessment.
