Long UVA rays: an ever-present and invisible danger


All year round, without realizing it, we are constantly exposed to long UVA rays, called passive exposure. These solar rays can travel through clouds, glass and even the epidermis down to the dermis

What are the effects of long UVA rays?

The longer the UVA rays, the more deeply they penetrate the skin. They sometimes cause skin damage which can be irreversible:

  • Pigmentation and color disorders, like pregnancy mask, dark spots and a gray complexion.
  • Sun allergies and intolerances: like all UV rays, long UVA rays can trigger the appearance of redness, spots on the skin and itching.
  • Photo-ageing or premature ageing: reduction in the skin's elasticity and slackening, which favors the appearance of wrinkles.


UV rays irradiate the earth's surface daily: 95% are UVA rays and 5% are UVB rays. Among them, long UVA rays represent 75% of the total radiation.
