As clindamycin is an antibiotic, you’ll need a prescription to buy it at your local pharmacy. There are some other acne treatments like salicylic acid, lactic acid, topical retinoids and alpha hydroxy acids that are available over the counter.
Acne treatment depends on your skin type, the kind of acne you have and the severity of your acne. Getting a treatment without consulting your doctor may sometimes give you severe side effects. Always take advice from a doctor as they’ll assess the condition of your acne and prescribe treatment that’s right for you.
