This hyaluronic acid essence contains large and small molecular hyaluronic acid. Large molecular hyaluronic acid forms a moisturizing film on the skin surface, locking in moisture and preventing skin from drying out. Small molecular hyaluronic acid can penetrate deep into the skin, replenish moisture for the skin and increase skin elasticity. It effectively improves skin dryness, roughness, and other problems, making the skin moisturized and smooth. The texture is light and easy to absorb. Suitable for all skin types, long-term use can keep the skin hydrated.
