Sunscreen / Sun ProtectionSunburn is your skin's reaction to ultraviolet radiation or 'UV'. Step outside without any form of protection, and UV (both UVA and UVB) will immediately start to penetrate deep into the layers of your skin.
Most of the visible signs of aging, including wrinkles and blotches, are caused by exposure to the sun. All types of sunburn, whether serious or mild, can cause permanent and irreversible skin damage and repeated sun exposure may increase your risk of developing skin cancer.
Sunbathing is not the only time when you need to be aware of the sun. You are most likely to get burnt when taking part in passive activities like walking outside, gardening or even eating lunch outdoors. By being aware of these facts and protecting your skin every day, you can avoid sunburn and lower your risk of skin cancer.
Your beauty routine should always include sun protection. Using sunscreen, wearing a hat and avoiding direct sun will help you to protect your skin and delay the visible signs of aging. The easiest, most inexpensive way to prevent skin aging is to use sunscreen. Wrinkles, sagging, and brown spots are created and worsened by the sun, so protecting yourself can have dramatic benefits. The best sunscreens protect against both UVB rays (ultraviolet radiation with wavelength between 290 and 320 nanometres), which can cause sunburn, and UVA rays (between 320 and 400 nanometres), which penetrate more deeply and cause skin to age with more long-term effects. Most sunscreens work by containing either an organic chemical compound that absorbs ultraviolet light (such as oxybenzone) or an opaque material that reflects light (such as titanium dioxide, zinc oxide), or a combination of both. Typically, absorptive materials are referred to as chemical blocks, whereas opaque materials are mineral or physical blocks. Today, many modern sunscreens use micronized zinc and titanium oxide which do not leave such an obvious trace on the skin.
