All you ever wanted to know about skin and dermatological disorders.
To avoid endangering your skin when in the sun, there are a few rules that must be followed.
The sun provides true benefits, but you must make sparing use of them. In particular, the use of a sun protection product is indispensable.
Interview with a dermatologist who discusses sun protection methods.
Laure was particularly prone to sunburn. To learn to better protect her skin, she consulted a dermatologist. Since then, she has been able to enjoy the benefits of the sun in complete safety.
UV rays only account for 5% of the sun rays that reach the earth, but they are very powerful.
UVA's account for 95% of the ultraviolet rays that reach the earth. Insidious because they cause no pain, UVA rays penetrate very deeply into the skin and can damage cells
FALSE
Tanning is the skin's defence mechanism against UVB rays. Yet UV tanning beds diffuse UVA rays in doses higher than those in sunlight: insidious because they are painless, they only provide a superficial tan and encourage the production of free radicals which are responsible for skin ageing and alterations in the cellular system. Therefore UV tanning beds speed up premature skin ageing and increase the risks of developing skin cancer.
FALSE
The skin has defense mechanisms to fight the effects of UV rays: it thickens and produces a pigment (melanin) which partially filters UV rays and gives colour to the complexion-- your tan. However, this "natural" protection against the harmful effects of UV rays is superficial because it only partially filters out UV radiation. A tan therefore does not exempt you from using a sun production product.
