Product Description Pentapeptide-18 is a new wrinkle removing polypeptide. Simulate the mechanism of natural enkephalin in vitro: outside the nervecells, it binds to enkephalin receptors, and ligands bind to receptors. Conformation changes start the cascade reaction in thenerve cells, leading to a decrease in its excitability: the activity of nerve cells is "down regulated" and the release ofacetylcholine is adjusted, so the muscle contraction will be slowed down, thus reducing wrinkles. Anti wrinkle and smoothskin。Pentapeptide-18 is a synthetic polypeptide, which can resist muscle contraction and facial expression lines, and has theeffect of anti wrinkle and smoothing skin.

It promotes the production of collagen and elastin, improves skin's elasticity and firmness, and reduces the appearance of fine lines and wrinkles. Lighten dark spots: Pentapeptide-18 can reduce pigmentation and inhibit the overproduction of melanin. It is used in whitening and lightening products to help improve uneven skin tone. Moisturizing: Pentapeptide-18 has strong moisturizing properties and can provide the moisture and nourishment needed by the skin. Therefore, it is often added to moisturizing products to enhance the moisturizing effect of the product and make the skin softer and smoother. Anti-inflammatory: Pentapeptide-18 has a certain anti-inflammatory effect and can reduce redness, swelling and inflammatory response of the skin. This has led to its use in skin care products to relieve issues such as sensitivity and acne.
