I use Pro-Ma Grace Cosmetics sunscreen with aloe it is wonderful stuff, but i only use it when i go into the full sun etc. it is quite expensive comapred to the ususal stuff u buy at normal stores, though i think of it as i would rather have the better skin and u dont need much either - it lasts me about 6 months for 1 tube. i cant use the normal sunscreens because there is just way too much oil and makes my acne break out all over my face. on normal days as an everday sunscreen i use Banta Oil-free Faces sunscreen gel, theres no oil at all in it, its pure gel sunscreen and doesnt put any oil on the face at all.
I really recommend these as I too know wot it is like trying to find sunscreen without making all your face flare up.
