I have severe folliculitis and I’ve had it since I was 8. Could Accutane cure my butt acne, hyperpigmentation, and scars?

acne can be "cured" with accutane but pigmentation and scarring needs lasers and skincare, for the buttock we have everyone use our body acne package + vivatia foam (on emeragecosmetics.com see link).  I suggest seeing a very well trained dermatologist.
Acne requires a combination approach to get long term improvement.  For all patients on isotretinoin, we require them to be on skin care such as vitamin C, glycolic cream, kojic acid serums in the morning and retinols and salicylic acid at night.   All of our patients get clear+brilliant non ablative laser along with a microsecond YAG laser such as aerolase or laser genesis and microneedling with PRP or microneelding RF like intensif or fractora monthly to help improve breakouts, speed the healing process, and improve scarring and facial redness while on the isotretinoin/accutane.  LED light therapy, cosmelan/enlighten peels, salt facial or dermalinfusion can be done as well to speed up the improvement. I sugges tyou go to an expert who combines skin care, lasers, microneedling, PRP, and facials while on oral medications for acne.  Best, Dr. Emer.

Thank you for your question. Accutane is effective in treating difficult or stubborn cystic acne, but does not treating any scars or hyperpigmentation. I highly recommend you consult with a board certified dermatologist to have your skin evaluated and to discuss appropriate treatment options that best suits your skin. Take care and good luck.
