Pentapeptide has only 13 amino acids, small molecular weight, and is easily absorbed. One of its significant effects is that it can promote collagen production and indirectly repair micro-damage to the human oral mucosa. The anti-aging effect of pentapeptide can prevent and improve gum recession. In addition, pentapeptide can promote the proliferation of hyaluronic acid and elastic fibers, which can effectively activate hyaluronic acid synthesis, which is essential for maintaining oral moisture and relieving dry mouth.
