The A'pieu Pure Block Natural Water Proof Sun Cream SPF50 PA+++ is a hybride sunscreen (contains both chemical as mineral filters) that offers protection against both UVA- and UVB rays. The formula is waterproof and since the sunscreen is enriched with watermelon, it will have antioxidative benefits as well. The sunscreen will help regulate the oil production.
One of the most important factors of aging and the development of hyperpigmentation and melasma is (excessive) exposure of the sun. We seperate three kinds of uv rays: UVA (UVA1 has a reach off 340-400 naometer and UVA2 has a reach of 320 en 340 nanometer), UVB (320-280 nm) and UVC (280-100 nm). UVC is blocked by the ozon layer, so we aren't exposed to rays under 280 nm.
