I can understand your concern.
Acne keeps recurring till around 25 to 26 years.
If u have normal periods you are less likely to have hormonal
Acne needs to be treated. Treatment prevents ugly scars
Since you have small lesions you can treat it with creams and short course of antibiotics.
Doxycycline 100 mg daily for a month. Benzoyl peroxide
gel in the morning and tretinoin
cream at night will be good.
Also use salicyclic acid face wash. Do not pick on acne. Or they will leave marks or scars.
Scars can be treated with laser or dermaroller
Please let me know if you have any queries.
