Isotretinoin is not recommended for patients with mild acne and topical medication is recommended. Isotretinoin is indicated for nodular cystic acne, acne that has not responded well to other methods of treatment, as well as violaceous acne and coalescent acne. It is generally used for the treatment of severe acne and has some side effects, so it is not recommended for patients with mild acne. For mild acne, topical retinoids such as adapalene and tazarotene are recommended to help dissolve acne and reduce inflammation. Topical benzoyl peroxide can also be used as prescribed to kill Propionibacterium acnes and dissolve acne. For patients with mild acne, they need to go to a regular hospital to consult a doctor and use medication under the doctor’s guidance, not without authorization.
