Spring has rapidly changed into summer, the days are getting longer and the urge to spend more time outdoors has hit. You know you must apply sunscreen, you think you know what all the numbers and letters on the bottle mean, but do you really?
- Broad Spectrum – Originally products labeled as such gave protection only against UVA rays. Currently, products labeled “broad spectrum” must protect against both UVA and UVB rays
- UVA – Solar rays that cause skin cancer and wrinkling
- UVB – Solar rays that cause burning and skin cancer
- SPF ( Sun Protection Factor) – The length of time you can stay in the sun before burning. The higher the number the longer you can stay in the sun
Dermatologist suggest using products labeled “broad spectrum” that have an SFP rating of 30 to 50. There’s no evidence to show better protection with higher numbers. Be sure to apply about 3 tablespoons of sunscreen every two hours. If you’re sweating heavily or swimming, apply it more often.
