THE SUN FRIENDLY ENEMY...

The sun is indispensable to our health. It promotes psychological well-being and stimulates the production of vitamin D which helps maintain good bone health and dental health.

Nevertheless, ultraviolet (UV) A and B rays that reach and penetrate skin cells can cause irreversible damage.

The UVA and UVB are differentiated by their intensity and their ability to penetrate the skin so more or less profound:

• The energy of UVB is responsible for “sunburn" (burning of the skin). Their penetration is limited to the epidermis.
• The UVA meanwhile, through the stratum corneum to the dermis damaging its elastin and collagen fibers. They are considered the primary factors of skin aging.
• The sun is also responsible for a large production of free radicals that alter the cell membranes.
