Sunscreen facts
Need for protection from sunlight
- Exposure to both ultraviolet A (UVA) and ultraviolet B (UVB) rays results in cumulated damage that leads to skin aging, cataracts, corneal burns and the formation of skin cancer.
- UVR penetrate deep into the skin support structure, affecting the skin's immune system and increasing cancer risks.
- Eighty percent of lifetime exposure to sunlight occurs before the age 18.
- UVA rays penetrate glass/windows.
- Eighty percent of damaging rays can get through clouds.
- Even one blistering sunburn in childhood could result in the development of melanoma later in life.
- Sixty percent of the day's sunburning radiation occurs between the hours of 10 a.m. and 4 p.m.
- Reflection from sand, water and white surfaces, such as a deck or bulkhead on boats, results in substantial UVR exposure.
- Heat and brightness are not indicators of UV intensity.
