Everything you've always wanted to know about moles...

A mole, also called a naevus, consists of a mass of brown-coloured cells that are generally found in the skin or mucus membranes. Known as melanocytes, these are the cells behind tanning or dark skin. Children have no moles when they are born. They begin to appear between the age of six months and a year and then continue to appear until adulthood.


Between childhood and adolescence, sun exposure influences the number of moles that can appear on the skin as well as their size. However, the more moles a person has, the greater their risk of developing a skin cancer, since 35% of skin cancers actually develop from a pre-existing mole1. It is therefore essential to effectively protect children and adolescents from the sun to minimise the appearance of new moles. In addition, overexposure of existing moles to the sun influences the development of lesions that may turn out to be cancerous. It is therefore also important to adopt good habits to protect your moles from UVA and UVB rays, just as you do with your skin.

To meet these particularly demanding needs, La Roche-Posay laboratory formulated the Anthelios range of sunscreens that combine very high UVA and UVB protection. Anthelios comes in a range of textures to meet the needs and expectations of the most sensitive skin. Looking for a fast-absorbing tinted cream, an ultra-light fluid gel, or a body oil? Visit the Anthelios sunscreen range.

To help you stay vigilant and keep an eye on your moles, the Mole Checker developed by La Roche-Posay allows you to map your moles and monitor their evolution between dermatologists' visits. Remember, the earlier skin cancer is detected, the greater the chances are of it being cured.


As 50 to 70% of skin cancers are caused by overexposure to UVA and UVB rays, it is essential to follow a few simple rules in addition to applying sunscreen:

  • Avoid exposing your skin to the sun between the hours of 12pm and 4pm
  • Opt for shade rather than direct exposure
  • Apply generously to all exposed areas of clean dry skin, 15 to 20 minutes before sun exposure. Reapply again after exercise, swimming or towelling or at least every two hours
  • Reduce children's sun exposure as much as possible because their skin is much more sensitive than adults' skin. Clothes (hats, t-shirts and sunglasses) are still the best protection against UV rays
