Does my face have some kind of infection after IPL? (Photos)

this is likely a contact allergy and needs proper dermatological treatment.
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.

I would definitely return to your dermatologist as I would say this is not a normal reaction from IPL. You might have had an allergy to a numbing cream they used, or even a post procedure cream. Best to be seen. It definitely looks like some form of contact dermatitis. "This answer has been solicited without seeing this patient and
