I would Goggle this and go to Drugs.com to get the most uptodate info on exactly the preparations you are thinking about using. Might also discuss with a Dr in your local.

UV400 protects against almost all UV-A and UV-B up to 400 nanometers, at which point visible light begins. So, essentially, UV400 is the same as 100% protection against UV-A and UV-B.
