Sunscreen and SPF
Many of my patients, readers and viewers are confused when it comes to sunscreen and SPF. What is the right SPF for me? Should I choose chemical or non-chemical sunscreens?
SPF (Sun Protection Factor) is a numbering system which shows a sunscreen's ability to protect against UVB. 15 is a good choice, however, some people may need more - in that case I recommend a non-chemical sunscreen of SPF 26 for face that protects against both UVA and UVB rays.
If you have sensitive skin, are taking medication that increase sensitivity to the sun and/or plan to have prolonged exposure to the sun, even the highest SPF will not be adequate to protect your from visible signs of damage such as sunburn, increased risk of wrinkles and skin cancer, etc. In these situations, your best defence is to wear a hat and protective clothing.
