The PCA Skin Active Broad-Spectrum SPF 45 is a Skin Cancer Foundation recommended formulation that provides water-resistant, broad-spectrum protection from harmful UV sunrays. The sunscreen has been tested to protect the skin for up to 80 minutes in water or while sweating. Active Broad-Spectrum SPF 45 is formulated with Zinc Oxide that provides broad-spectrum UV protection by reflecting, scattering and absorbing UV rays, Caffeine and Silybin, which are important antioxidants that further protect the skin from damaging UV rays, and Octinoxate that helps to absorb and filter UV rays. Ideal for all skin types and especially for those with active lifestyles such as running and swimming as the water-resistant sunscreen will not drip into the eyes due to perspiring.
