Skin cancer can occur when healthy skin cells when subjected to ultraviolet radiation from the sun. There are three common types of skin cancer including melanoma, basal cell carcinoma and squamous cell carcinoma. Melanoma is recognised as the most dangerous form. According to the Cancer Council of Australia, a staggering 2 in 3 Australians will be diagnosed with skin cancer by the time they are 70 years old. Skin cancer incident rates in Australia are continuing to increase which is partially attributed to the depletion of the ozone layer resulting in the increase in UVA intensity and also over exposure to UVA radiation from outdoor activities. Fortunately, there are steps that can be taken to reduce the risk of overexposure. These include wearing protective clothing during days and hours of extreme UV intensity, using an effective sunscreen that offers broad spectrum protection (specifically from UVA radiation) and regular reapplication of the sunscreen. UVA radiation produces wavelengths around 320-400 nm which enables penetration through the epidermis into the dermis layer causing skin damage, photo-aging, wrinkles and skin cancer.
Careful selection of an effective sunscreen is CRITICAL. Protection from sunburn doesn’t necessarily provide protection from skin cancer! Not all sunscreens provide effective protection from UVA radiation. Nanosun Zinc Oxide is highly effective in protecting against both UVA and UVB radiation with the added benefit of being transparent when applied to the skin. Micronisers has spent 15 years in development and testing of its dispersions for use in sunscreen formulations. The innovation has enabled our Nanosun zinc oxide powder and dispersions to be added into most topical sun protection formulations. This includes sunscreens for outdoor aquatic and sporting activities, children’s sun care products and daily personal care and cosmetic products.
