I tried two sunscreens:

1) Avene Very High Protection Emulsion SPF 50+

-I wouldn't recommend this with tretinoin

-Leaves white cast

-Smells bad

-Not good with dry skin

2) Vichy Capital Soleil Mattifying Face Fluid - Dry Touch SPF50+

+Does not leave white cast (if applied carefully)

+Doesn't look greasy at all

+Mexoryl-based photostable broad spectrum UVA and UVB protection

-Just a little problematic with dry skin (dryness caused by tretinoin). Not too bad though. Maybe I should look for a better moisturizer.

-A little comodogenic? Don't know yet.

So I'm gonna continue using Vichys sunscreen till I find a better one.
