Why Protect Against the Sun?
Melanoma, the most dangerous form of skin cancer, is associated with severe sunburns often occurring before the age of 20. Therefore, protecting your child against sunburns early on in life is essential. According to the Skin Cancer Foundation, it is important to protect your family's skin from both types of harmful rays:
UVA rays pass through the ozone layer, and account for 95 percent of UV radiation that reaches the Earth. They can pass through glass and windows, and penetrate the skin more deeply than UVB rays. UVA rays are a main contributor to skin aging and wrinkling, and they play a role in, and may even initiate, skin cancer.
UVB rays are also dangerous, and are the main cause of skin reddening and sunburns. UVB rays do not penetrate the skin as deeply as UVA rays, and do not pass through glass or windows (unlike UVA rays, which can pass through glass). UVB rays mainly cause damage to the superficial layers, and also contribute to cataracts, immune system damage, and skin cancer.
