I understand from your question that you may be suffering from a type of acne called nodular cystic acne? Aczone is a possible treatment option but is quite outdated and not a first line topical medicine for acne. This drug review shows that it has lower response rate that currently available treatment options.
There are good oral and topical treatments available for nodular cystic acne. I would advise a proper consult with your dermatologist or aesthetic doctor for an assessment and treatment, so as to prevent the scars they leave behind. You can leave a treatment quote enquiry in the box below!
