Here are four commonly-held myths that I'd like to clear up!
SPF - higher number is better, right?
Yes and no. The higher the number, the more powerful and long-lasting protection you will get. SPF 50 blocks more of the harmful rays than SPF 30...and so on.
Sort of.
It's really best to have 3 things in an SPF:
1. A higher number (something over 30 is best)
2. Broad spectrum - key to a good sunblock is one that blocks both UVA and UVB rays, not just a high number!
3. Physical vs. chemical: A physical sunscreen is often a more "natural" option and offer a serious sun barrier.
