Did you know that approximately 80 percent of premature extrinsic aging is caused by the sun?
There are two types of ultraviolet rays that are generally not filtered out by the ozone layer, UVA and UVB.
UVA rays account for 95% of the solar radiation that reaches the earth. They penetrate the skin more deeply than UVB rays and can penetrate clouds and glass. They are the rays that cause the skin to tan and are present on the atmosphere with equal intensity year round. Tanning is actually an injury to the skin’s DNA. The skin tans in an attempt to prevent further DNA damage. UVA rays cause the skin to prematurely age and wrinkle and damage cells in the basal layer of the skin, where most skin cancers occur. They have been proven to contribute to the development of cancer.
UVB rays do not penetrate the skin as deeply as UVA rays. They damage the skin’s surface in the form of sunburns. Although they are always present in the atmosphere, they are strongest between April and October, from 10 am to 4 pm. UVB rays are mainly responsible for the development of skin cancer.
Environmental exposure, pollutants, air quality and humidity also affect the skin’s health.
Poor maintenance and home care can also be a contributor to skin problems.
Misuse of products or poor facial treatments can be detrimental to maintaining a healthy and attractive complexion.
Preventative measures for skin care include:
- avoiding the sun and wearing sunscreen, which is the best protection for our skin.
- Proper home care, professional skin treatments and ingredients such as antioxidants, lipids, and alphahydroxy acids can be beneficial.
- A good diet
- water intake
- exercise and other healthy practices all have a positive effect on our health and our complexion.
