@sushikandi: Sis, ug para sa tanan pang FYI lang spf rating doesn't really matter. The spf number is just multiplied by 10minutes and that's how long you'll get protected from UV rays. Sample spf 15 x 10mins = 150mins of protection. I don't think you'll be out in the sun that long.

, what matters is the type of rays the sunblock protects you from. Usually the marketed sunblocks protect you from UVA ra, but there are also UVB rays and several others. It's best if you get a sunblock that protects a whole range of spectrum even at a low spf rating, minimum of 15 is recommended. I hope this helps. Kani jud commercial dili mo inform sa mga tao.
