I have a minor issue with redness/pink skin on my face in the T area that I'm trying to reduce. I bought Bioderma AR for this purpose, and so far I've been applying it post-cleansing across the T area where the redness is, and then applying my regular Cerave moisturizer all over my face. The amount you get in the Bioderma bottle is quite low and I'm not sure if I'm supposed to be lashing on large amounts or just small and targeted usage.

The Cerave is put on top as additional moisturizer therefore, as well as to cover the remainder of my face.

Does this strategy make sense? Is the Bioderma still able to do its job in such a setup? Thanks
