Palmitoyl Pentapeptide-4 is carried into the skin and stimulates the production of collagen, glycosaminoglycans (GAGs), and fibronectin (all important parts of healthy, smooth skin).
Palmitoyl Pentapeptide-4 decreases the appearance of facial lines and wrinkles. A study shows biopsy proof of improvements in wrinkle depth, skin density, and overall roughness.
Palmitoyl pentapeptide-4 is at least as effective against wrinkles as retinol but does not cause skin irritation, which is a common side effect of retinoids.
Palmitoyl Pentapeptide-4 is effective in improving the appearance of photo-aged skin, or skin that has had significant sun exposure over time.
Products containing Palmitoyl Pentapeptide-4 are well tolerated.
