Ultraviolet rays can alter the skin’s DNA and fragment its nucleus. They also weaken the immune system. These effects increase the risks of genetic mutation, tumors, and skin cancer. By favoring free radicals and destroying collagen, UVAs also contribute to aging of the skin. That is why dermatologists recommend the daily application of high photoprotection against UVAs and UVBs. At Bioderma, we care for your skin’s needs. Photoderm erects a double barrier to encourage its immunity against the harmful effects of the sun: the best of external protection as well as Cellular Bioprotection®. This unique, patented and laboratory-tested technology protects your skin and activates your natural defenses.
