ZO Skin Health Daily Power Defense Serum is a lightweight, daily-use antioxidant treatment developed by Dr. Zein Obagi to strengthen the skin's natural barrier and defend against the environmental stressors that accelerate visible aging. Formulated with antioxidants, peptides, DNA repair enzymes, and ZO's exclusive ZPOLY™ complex, this fast-absorbing serum helps neutralize free radical damage from UV exposure and pollution while supporting the skin's own recovery process. With consistent morning and evening use, skin looks stronger, more hydrated, and more refined, with a visible reduction in the look of fine lines and wrinkles. Non-comedogenic and suitable for most skin types, it layers easily under moisturizer and sunscreen and works well alongside other ZO Skin Health products as part of a complete regimen.
