Hi, I'm 26 and I'm struggling with acne. My dermatologist recommended me some preparations that I use + vitamins (zinc, selenium), but I do not seem to help me (after about 4-5 months of daily use). I was recommended some cosmetics, but unfortunately I do not know how to apply it properly - I first used these products - bioderma sebium h2o cleansing water and bioderma sebium gel moussant. I used them as follows - I cleaned the face with a cleansing water in the morning and before sleeping through a tampon, and usually in the evening I then applied a gel (types of preparations) on the face - and in about 10 minutes I washed it off. As soon as I received these preparations, the pharmacies recommended this cleansing gel to me. I apply it by putting it on my damp face and after about 10 minutes I wash it off (usually in the evening, sometimes in the morning and in the evening). I use these preparations correctly at all (so far I have not used anywhere, so I ask so stupidly :))? On my last visit to the pharmacy and dermatologist, I was told that the Bioderma cleansing water I had used was, on the contrary, drying my skin and not being so beneficial to me. Could you recommend me some preparation for "oily / problematic skin? Thank you, nice rest of 2014!:) If
