Tetrapeptide-5（Cat No.:I037151）is a synthetic peptide composed of four amino acids and is commonly used in skincare products for its anti-aging and anti-inflammatory properties. It works by targeting specific skin mechanisms, particularly in reducing puffiness, swelling, and dark circles under the eyes. Tetrapeptide-5 is known to improve skin elasticity, promote collagen synthesis, and enhance the skin’s natural barrier function. It has been shown to reduce the appearance of fine lines and wrinkles, making it a popular ingredient in eye creams and anti-aging serums. Its gentle action makes it suitable for sensitive skin.
