Today I bought La Roche Posay Fluide Extreme 30+ since I didn't have anymore Avene left. Is 30+ really enough? I like this one a lot better than LRP Fluide Extreme 50+ because it dosn't give me the *ghost face* at all. Also, on the bottle it says UVA and nothing about UVA, does this me that I could still tan in the sun? UVA is what I'm concerned about because that's what makes wrinkles. Don't care about UVB.
