It is very important for pediatricians to advise parents about the dangers of too much sun. Sun damage is cumulative and a blistering sunburn doubles the chance of developing skin cancer. Squamous cell cancer, basal cell carcinoma, and melanoma have all been linked to sun exposure. UVB and UVA are both harmful to skin. Besides causing skin cancer, UV radiation has also been linked to formation of cataracts, premature aging, photoallergies, skin immune system changes, and sunburn.
Tanning is secondary to DNA damage and repair and the triggering of pigmentation formation.
It is recommended to use a product that covers both ranges. There are waterproof products and sunscreens that don't burn if they drip into the eyes, which are useful for protection during strenous exercise. Protection should be used even if the patient has a tan because a tan is not totally protective. Also, a lip protector should also be used. Make sure the sunblock is put on evenly and in all vulnerable areas.
