Skin Actives Hyaluronic Acid Serum is a lightweight moisturizing serum with the added anti-aging benefits of hydrolyzed collagen and the nutrient-dense benefit of our exclusive Sea Kelp Bioferment. This water-based facial serum uses the hydrating capabilities of hyaluronic acid to deeply moisturize oily and acne-prone skin types. Hyaluronic Acid Serum contains ingredients needed to help alleviate dry skin. The moisture provided in hyaluronic acid creates a barrier that hydrates skin. Hydrolyzed collagen supports skin’s synthesis of collagen. As part of the Flawless kit, the Hyaluronic Acid Serum can be used once or twice a day after cleansing with the salicylic cleanser.
