i went to my dermatologist and showed her my Neutrogena Ultra Sheer Sunblock in SPF 70...
she recommend that i don't use it, something about the chemicals seeps under your skin, and creates a chemical reaction underneath your skin to protect you from the sun... i didn't really get the scientific part of it... but she recommend that i use a sunblock/sunscreen that has TITANIUM DIOXIDE as an ingredient. right now i'm using La Roche-posay SPF 60 creme (anthelios XL)... i think it's okay... but it's a bit greasy for me... so i'm still in search for a non-greasy one w. the right ingredients
