The usual treatment for acne is a topical gel
containing an acne-fighting ingredient (clindamycin
, erythromycin, adapalene, tretinoin etc). However, these are safe to apply to the face, chest and back not inside the ear. You may require oral antibiotics such as Oxytetracycline 250mg twice daily, if you have moderately severe acne.
Most people outgrow their acne in their early 20s.
