“How do I know what is the right SPF for me?”
I am often confused with what could be the right SPF for my skin. Is there a way to figure this out?

The minimum SPF used in 30; must cover UVA/UVB and applied 20 minutes prior to exposure and reapplied every 2-hrs. The higher the SPF, the better!
Generally, there's no way to predict. It has more to do with how often you apply the sunscreen. 35 is the minimum, but I use 70 and up because I'm not reapplying it every 2-3 hours.

We tell people to use at least Xbox spf 40. The dog number is not the actual protection patients get. Studies are performed with an half inch of sunblock applied. No one applies that amount of sunblock.
The actual amount of pyotecyion you get is probably half the number on the bottle. We usually recommend a 30 so you get an spf 15 worth of coverage.
That amount of pyotecyion is usually adequate.

The best agents to protect you against the harmful effects of the sun are the physical blockers. This includes zinc and titanium dioxide. Anything above spf 30 gives you uvA and uvB protection. Sunblocks should be reapplied every 2 hrs.
You should always apply a sunscreen or sunblock that's at least an SPF 30 or higher. If you are swimming or perspiring a lot while outside, then make sure the type of product is rated as "very water resistant". You should also plan on re-applying it about every 90-120 minutes or more often if needed depending on the activity you are doing.
Without sunscreen, it takes 10 minutes to get a mild sunburn. Then, if you use a sunscreen SPF 15, it means, in theory, that sunscreen will protect you 15 times 10 minutes. In true life, sunscreens are diluted by sweat or when you go in the water, so sunscreen has to be reapplied more often.
When using a sunblock SPF of more than 40 will do. However not only the SPF is what matters, you need to look for UVA and UVB protection, need to look for two ingredientes Zinc oxide and Titaniun Dioxide. Also remember you need to reaply every two hour.
