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 a number of causes like Oily skin, clogged pores, bacterial infection, inflammation etc.. Sebonac gel contains active ingredient salicylic acid while Doxt SL contains doxyxyxline antibiotic and proiotic Lactobacillus.. You can continue using both of these and along with it you can also start washing face with salicylic acid containing facewash, apply a combination of Clindamycin and Benzoyl peroxide containing gels.. Apply Adapelene gel at night.. Exfoliate your skin twice a week and do cool compresses on face.. Take multivitamin supplements. Take a nutritious diet with more of green vegetables and fruits.. Avoid oily food and sun exposure.. Maintain cleanliness of face.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
