What are these rays and how do they damage the skin? UVA is a short range beam of ultraviolet light and UVB is a long range beam. An easy way to remember what beam effects what layer of skin is to recall that UVA light is an aging ray and UVB is the burning ray. UVB leads to superficial damage, such as erythema (pinkness) and sunburn. UVA penetrates the skin deeply to effect the dermal layer causing the skin to age and damages cell DNA possibly causing skin cancer!
Broad spectrum sunscreen blocks both UVA and UVB rays preventing the long and short term damage of the sun’s rays.
The proof is right in front of us now as consumers that sunscreen is the most important skin care product that we have available!
Protection is essential. -Diane
