Skin Activator Serum with Hyaluronic Acid + Niacinamide

Serum · 30 ingredients

A hydrating serum formulated with four types of hyaluronic acid, peptides, and noni fruit extract to flood the skin with moisture, soften the appearance of fine lines, and support natural collagen production. Niacinamide works to visibly even skin tone while targeting pores and pigmentation, and prickly pear cactus extract helps soothe and reinforce the skin's barrier. The formula is well-suited for those concerned with redness, signs of aging, and dehydration.
