UVA & UVB Rays and Aging
There is no arguing the fact that sunshine is one of the most important ingredients for the ultimate summer experience, but that “healthy glow” of summer is deceiving; further, it is decidedly unhealthy.
According to the American Academy of Dermatology, most sun exposure occurs before the age of 20, when the skin is more vulnerable. Sunburn is caused by Ultraviolet Radiation (UVA, UVB and UVC rays). Skin, whether light or dark, can and will burn, given enough sun exposure.
Though we often see no immediate damage or scarring to the skin, you may rest assured that there is a price to pay in the long run. Over exposure can cause most forms of skin cancer as well as many signs of skin aging.
According to leading authorities on UVA & UVB rays, people should stay out of the direct sun from 11 a.m and 3 p.m., when 70% of the harmful ultraviolet radiation occurs. Babies up to 6 months should be shielded from the sun entirely and should only be exposed to a physical and not chemical UVA/UVB block.
In order to protect our skin, we need to wear sunblock daily, on all exposed areas and avoid “baking” in the sun. Additionally, when we know we will be enjoying water sports, sunblock should be reapplied every 2 hours.
Sunblocks are not all created equal. The rank of a good sunscreen depends on the ingredients, not the number on the bottle. The three most effective ingredients are titanium dioxide, zinc oxide and parasol. Use a sunscreen that is “broad spectrum” – meaning it protects against both UVA and UVB rays, and at all cost, avoid PABA.
E International UVA UVB SPF 46 sunblock is not greasy, nor does it inhibit the application of make-up. ! Invest in one today and if it's good enough for your baby's skin, it's good enough for you!.
