When it comes you have to take treatment. And treatment is given based on severity of acne. For mild cases, topical antibiotics like clindamycin, azithromycin, retinoids like tretinoin are given. For moderate degree, oral antibiotics like azithromycin, doxycycline, topical creams like clindamycin, tretinoin, adaplene, benzyl peroxide are given. In severe cases, oral retinoids like isotretinoin are given. This given long term relief. But has its side effects like increased dryness (you can use moisturiser), alters cholestrol, teratogenic.
