Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain Acne can occur due to causes like oily skin, clogged pores, bacterial infection, inflammation etc..
Acretin is topical
Isotretinoin that is a
retinoid and should be continued as it helps in resolution of Acne although can take some time..
As far as Bioderma gel is concerned it is nourishing facewash as well as reduce oil production so can help in reducing pimples and can be continued..
You should also apply topical ointment containing
Clindamycin and
Benzoyl Peroxide..
Do cool compresses over face..
Scrub your face twice a week to unclog the pores and remove dead skin..
You can also apply a non comedogenic sunscreen lotion when exposed to sun..
You can also go for treatment like
Microdermabrasion and chemical peeling and Oral Medication like antibiotics and retinoid can also be advised to you..
Hope this information helps..
Thanks and regards.
