Thanks for posting on HCM
You are most probably suffering from septic or inflammatory acne (i.e pimples superinfected by bacterial infection). In order to deal with this you will need lotions such as salicylic acid
or benzoyl peroxide
5% associated with oral antibiotics
such as doxycycline or clindamycin (could be applied topically too). You will need to apply them 1-3 times daily for a month. You can also pay a visit to a dermatologist
for proper review and medications.
Hope this helps
