Very Water Resistant - For Extreme Exposure Oil-Free. Powerful Sun Protection SPF 45 Sunscreen Cream is a broad-spectrum physical sunscreen that protects against the sun's harmful UVA/UVB rays and is the only sunscreen that contains an Iron-encapsulating Chelator. This Chelator removes Iron residue left on the skin by tap water and perspiration, which helps in skin cancer prevention and promotes healthy skin. This multi-functional product protects, prevents aging, moisturizes and promotes collagen growth. While SPF 30 is recommended for everyday use, Powerful Sun Protection SPF 45 Sunscreen Cream is necessary for extreme and prolonged exposure. Unlike sunscreens that leave behind a heavy, white residue this very water resistant, oil-free formula quickly absorbs into the skin and dries clean and clear. It retains SPF protection after 80 minutes of perspiration or activity in the water and will not sweat off, making it ideal for individuals with extremely active lifestyles, including sports enthusiasts. Chelating agents help prevent clogged pores and breakouts, a common side effect of heavy sunscreens. Clinically-proven, powerful antioxidants such as Blueberry Extract and Lycopenes shield against premature aging and wrinkles while working to repair existing damage. Humectants help skin retain moisture during sun exposure, a time when skin needs it most. This lightweight, yet impenetrable formula will not drip or run. Benefits: Protects skin from aging and sunburn with four forms of broad-spectrum UVA/UVB protection; providing both a physical and chemical sun block. Encapsulates harmful Iron molecules with chelating technology to provide additional protection from the sun. Repairs and reverses existing sun damage with powerful antioxidants. Retains skin?s natural moisture barrier during sun exposure with humectants. Very water resistant formula provides superior coverage for prolonged exposure. "This oil-free formula offers very water resistant protection against extreme and prolonged exposure, and is ideal for individuals with active lifestyles. The chelator removes iron left on the skin from tap water, which helps in skin cancer prevention, and the formula also contains wrinkle-fighting antioxidants and humectants." - Dr. Dennis Gross.
