Our hero ingredient offers a natural non-toxic sunscreen which prevents premature aging, skin from drying out, and potentially from skin cancer. Zinc oxide sits on the surface of our skin and is not absorbed, forming a natural protective barrier that filters out harmful UVA and UVB light rays, preventing them from penetrating the skin and causing cell damage. Zinc oxide also has an astringent property which reduces oils form forming on our skin and reduces pore size. As such it is an effective acne treatment and reduces the number and severity of acne breakouts. Zinc oxide may also assist in the production of collagen and skin healing.
