Description

Zinc Oxide is powdered, oxidized zinc derived from the naturally occurring mineral, zincite, and routinely used in a wide range of consumer products. Zinc Oxide provides great soothing effects for use in many skin preparations. It physically works to provide 28 times the skins natural protections against harmful UVA & UVB rays.
A natural anti-inflammatory with mild antibacterial properties, Zinc Oxide is used in a wide variety of applications such as skin protectants, nappy rash ointments, sunscreen products, soaps and in ointments to aid those prone to acne. Used in sunscreens and mineral makeup it provides high protection for the skin from UV and other damage. When used in sunscreen products, Zinc Oxide acts as a physical block to the sun’s ultraviolet (UV) radiation, helping to reduce or prevent sunburn and premature aging of the skin. Because zinc oxide is not water soluble, it needs to be combined with a carrier agent to be most effective. Some lotions or creams contain zinc oxide so that the oily substances seep into the skin; zinc forms a barrier over them that keep moisture locked in place.
