Invisible Zinc Face & Body 2Hr Water Resistant Spf50 75gWith a high SPF rating, Invisible Zinc Face & Body SPF50 acts as a protective barrier between your skin and the sun, one of the main catalysts for skin ageing and wrinkles. The key ingredient is zinc oxide, a naturally derived mineral reflector that, although invisible to the naked eye, creates a reflective shield on the surface of the skin to protect it from the harsh rays of the Aussie sun.
