Thank you for your question.
Any sunscreen that you use and use often will work well! There are two main types of sunscreen/sunblock: chemical sunscreens and physical sunscreens.
Chemical sunscreens have chemicals that absorb and neutralize the UV rays. These primarily include avobenzone, oxybenzone, and others.
Physical sunscreens block and deflect the UV rays and contain either zinc oxide or titanium dioxide.
Here's a table to help you out:
Common Sunscreen Ingredients:
Ingredient UV Protection Chemical/Physical
Avobenzone UVA Chemical
Oxybenzone UVA & UVB Chemical
Homosalate UVB Chemical
Octocyclene UVA & UVB Chemical
Octinoxate UVB Chemical
Octisalate UVB Chemical
Zinc Oxide UVA & UVB Physical
Titanium Dioxide UVA & UVB Physical
I'm biased towards the physical blockers - there's less risk of allergy and they do an excellent job at protection. They tend to be somewhat thicker though, but there are good brands such as Solar Protection Formula and TIZO3 that are very elegant.
Excellent chemical blockers are LaRoche Posay AntiHelios with Mexoryl and Neutrogena brand with Helioplex.
There are also combination chemical and physical blockers. Simply read the ingredients on any sunblock you are thinking of buying. Anything over SPF 15 is great, but aim for over 30 at the very least.
Hope this helps!
