Neostrata Redness Neutralizing Serum is a cooling and hydrating serum that targets both skin redness and blotchiness. Formulated with Neostrata® BioCalm Complex, a proprietary blend of ingredients, this product contains PHAs as well as a blend of antioxidant extracts. The resulting formula soothes sensitive skin, improves its resilience, and visibly improves the appearance of uneven, blotchy skin.
