Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that pimples and blackheads can occur due to a number of causes like clogged pores, hormonal imbalances, oily skin, bacterial infection, inflammation etc.. In your case it seems most probably be due to hormonal imbalances.. I would suggest you to take a combination of antibiotic and anti-acne treatment.. You can wash your face with Salicylic acid and glycolic acid containing facewash.. You can apply a combination of ointments/creams containing Clindamycin+ Niacinamide and Clindamycin.. You can also apply Retinoids like Adapelene gel at night in a thin layer over pimples.. You can do cool compresses over the pimples.. Exfoliate your skin with a gentle scrub to unclog the pores.. You should avoid oily food.. Take a nutritious diet with ample of green leafy vegetables, fruits and drink plenty of water.. Always apply sunscreen lotion when exposed to sun.. You can also get treatment like Microdermabrasion and chemical peeling done.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
