As we age, the amount of moisture in our skin decreases, causing the skin to lose its elasticity. Hyaluronic acid is a vital component of skin health due to its exceptional ability to retain moisture (it can hold up to 1000 ml of water per gram of hyaluronic acid). Lhamour's Repairing Hyaluronic Serum uses vegan hyaluronic acid to enhance skin elasticity and texture. When applied in the form of a serum, hyaluronic acid creates a permeable layer on the skin that penetrates into the dermis, increasing the skin's elasticity and hydration. This protective barrier on the skin seals in moisture, giving the skin a youthful and radiant appearance that you will love!
