Dermalogica's Skinperfect Primer SPF 30 is a primer that helps smooth fine lines, brighten, and prep for makeup application and flawless skin. Blend over moisturizer or go a step further and prep for makeup application. Broad spectrum and physical sunscreens shield against sun damage triggered by UVA and UVB light. Hyaluronic acid provides hydration, while a nourishing peptide stimulates collagen production, helping to reduce wrinkles, and increasing skin firmness. Smooths fine lines, brightens and primes for flawless skin, and make-up application. Velvety formula helps even out skin texture, creating a smoother surface for a "soft focus" effect. Use as the last step in your skincare routine to seal in your products. Wear alone for the "no make up" makeup look.
