treatment of acne
depends on the stage and severity of the condition.
very good results can be obtained if you are under regular treatment- the duration of the treatment lasting from 6-9 months.
the problem of relapse occurs because most of the times either the medicines are not applied properly or not applied for the needed duration or the treatment is stopped midway or irregular.
More than antibiotics for prolonged duration what is needed is topical retinoids
for six to nine months
please visit the nearest dermat who will decide the stage and chalk out a management plan for you.
also one thing you need to strictly follow is that you need to continue the medicines for atleast 6-9 months if you want to get rid of acne for quite a long long duration.
