How it works

This product functions primarily as a protective primer, aiming to offer sun protection and prepare the skin for makeup application. Zinc Oxide acts as a physical barrier that deflects UV radiation, aiding in sun protection. Dimethicone adds a silky-smooth layer that helps in evening out texture, while Cyclopentasiloxane enhances the ease of application, allowing for an even spread. Caprylic/Capric Triglyceride and Glycerin contribute to skin softness and hydration. The Peptide-Rich Plasma introduces peptide components that work to condition the skin. Sodium Hyaluronate and Lactic Acid also support skin hydration and conditioning, which may promote an improved skin surface appearance.
