Hello ! Everything is in the title. I'm asking this question because in France, Epiduo is very very expensive and on the other hand, Adapalene and Benzoyl Peroxyde are two cheap products when single. Second question : Why is retinol working everywhere on my face except on my nose ? I'm using alternately tretinoin 0.05% / adapalene 0.1% with a good skincare routine for almost two years now and my acne on my nose didn't get any better (frequent red bumps, lots of blackheads, redness...).
