Makeup: Adds sheer glowy (never glittery) radiance that mimics a fresh-from-the-facialist glow. Layers beautifully under Best Skin Days when you do want coverage. Skincare: Time-release vitamin C works all day to support skin’s natural collagen and defend against oxidative stress, so skin looks even, hydrated, and smooth. Niacinamide helps even tone and texture while vitamin E, chamomile, and allantoin hydrate and soothe. Protection: 2-in-1 UV defense from broad spectrum SPF 50 UVA/UVB plus antioxidants that neutralize free radicals from UV, pollution, and visible light. Non-nano zinc oxide calms and protects with no white cast.
