For the past century, zinc treatments have been used on dry skin, acne, dermatitis, eczema, rashes, wounds and other skin problems in many western countries. Zinc oxide is also a powerful sun blocker against UVA and UVB rays. But many products on the market today that contain zinc also contain synthetic chemicals that diminish zinc’s beneficial properties.
Zinc is the most common trace element in your body, with 20% stored in the skin. It is an important part of your diet, boosting your immune system among other things. However, zinc also holds many benefits for your skin when applied topically.
This is probably because skin is in a constant state of renewal and hundreds of enzymes that drive this renewal depend on zinc to function. Its enzyme regulating effects have also been found to help stimulate the healing of wounds and decrease inflammation and bacterial growth. Similarly, zinc is thought to improve acne by working on the bacteria present in lesions while also slowing the production of overactive oil glands.
Recent debate has centred on whether nanoparticles in sunscreens and cosmetics are safe. Pharmaoil guarantees the use of Nano-free zinc oxide in all its products containing zinc.
