Sunburns and skin damage are caused by exposure to too much ultraviolet (UV) light
UV radiation is a wavelength of sunlight in a range too short for the human eye to see. UV light rays that reach the earth are divided into two wavelength bands — ultraviolet A (UVA) and ultraviolet B (UVB). Commercial tanning lamps also produce UV light. Despite appearances, you can still sunburn on hazy or cloudy days. As much as 90% of UV rays pass through clouds. Intense or repeated sun exposure accelerates aging and increases risk of various skin diseases, including actinic keratoses and skin cancer. The sun also contributes to dry, rough skin, deep wrinkles, age spots and fine red veins on the nose and cheeks.
People with fairer skin are more likely to sunburn than are people with dark skin, since those with skin that is darker have more melanin. Although melanin offers certain protection from sunburn, it does not protect against UV-induced damage to the skin. Regardless of skin type, the sun’s energy pierces deeply into skin and can damage the skin’s delicate cellular structure.
You can prevent sunburn and related skin conditions by protecting your skin with clothing and sun block whenever you are outdoors. It is important to note that some common sunscreen ingredients are suspected carcinogens and/or hormone disrupters. Educating yourself on product ingredients and their effects are on your skin is vital.
Zinc oxide is a mineral that provides great UVB/UVA protection, has anti-inflammatory properties, and is considered a natural nontoxic sunscreen. Vivoderm Zinc cream contains Zinc Oxide as well as other beneficial ingredients for sun protection and skin healing.
