Vitamin C is one of the best antioxidants for the skin. This product contains a blend of vitamin C, which is known for its ability to brighten the appearance of hyperpigmentation, as well as ferulic acid and niacinamide that are known to defend against environmental aggressors and neutralize free radicals that could otherwise cause premature aging. The addition of hyaluronic acid provides deep hydration and helps to provide smooth and plump looking skin. Use three to five drops each morning and/or evening by pressing the serum onto the skin with fingertips. Recommended for the face, neck and décolleté. Best followed by a mineral sunscreen for full UVA/UVB protection. Best for environmentally induced skin sensitivity, photodamage, premature aging, hyperpigmentation and skin dehydration.
