Bioderma Photoderm Aquafluide SPF50+ is a high protection sunscreen with an invisible dry-touch finish. This water-resistant formula provides broad spectrum UVA/UVB protection while maintaining a lightweight, non-greasy texture that absorbs quickly into the skin. This sunscreen is designed for daily use and is suitable for sensitive skin. The formula features Bioderma's patented Cellular Bioprotection technology that helps protect skin cells from UV damage. It has a mattifying effect and leaves no white cast on the skin. The product should be applied generously 15-30 minutes before sun exposure and reapplied every 2 hours or after swimming/sweating.
