This is the second day I have it after a night and I still don't know the cause. Redness at first and now just like this picture, it's really painful but not itchy
Looks like zona zoster, This location may be dangerous, so you should go to a dermatologist..
New cosmetic products? Maybe Contact dermatitis. Apply mupirocin and topical betametazone cream on lesions.
In this kind of lesions painful and without Itching it should be rouled out an herpes infection...
You can change the soap. Use dermadev soap. Wash your face regularly and you can use clindamycin gel phospahte and benzoyl peroxide gel
