Sunscreen is a must-have when you are doing activities outdoor. This is especially so in the summer season when the sun is strong and there’s increased outdoor activities. You need sunscreen to protect your skin from the uv rays.
The use of sunscreen products should not be limited to only going to the beach or swimming at the pool. Put on your sunscreen whenever you expect to be out in the sun for it will protect your skin and provide anti aging skin care.
The sun generates 2 types of ultraviolet (UV) rays. UV A has a longer wavelength, and UV B a shorter wavelength. Short term sunburn and some forms of skin cancer are primarily caused by exposure to UV B, while skin wrinkles and also aggravation of cancer is from being exposed to UV A.
Wearing sunscreen helps skin aging. Put on sunscreen at least every 2 to 3 hours while you are exposed to the sun. Doctors recommend using about one ounce of sunscreen for all parts of the body, including the face. For people who have sensitive facial skin, there are sunscreen made especially for the face. Fail to wear sunscreen puts your skin at risk of photo-aging, resulting in long term skin damage, including the appearance of wrinkles.
SPF label on sunscreen is denoted by a number and this stands for the sun protection factor of the product. If you are for a day at the beach, try to use sunscreen with a minimum of SPF 15. Higher numbers for SPF does not mean that you can apply lesser, or forget to reapply after a few hours. Even water proof sunscreens need to be reapplied after spending time in the water for more than 30 minutes.
New ingredients such as Helioplex and Meroxyl are now introduced in sunscreen products. Helioplex improves the protectant factor of sunscreen, making it last for 4 hours or more on the skin, instead of 2 to 3 hours only. Meroxyl prevents penetration of the UV rays through the skin, in fact converting this to be given off as thermal energy.
