Thanks for writing to us.
I would advise you to stick to your doctor's precription for acne control.
But for blackheads, you may add these suggestions in your skin care
use a salicylic acid
based face wash as it unclogs pores
Get your comedones extracted by a certified dermatologist
atleast once in a month
gel in night over comedone prone areas.
You may also take few sessions of salicylic acid peels.
HOpe this helped you out.
