New cosmetics? Different water? Hormonal changes? Sensitivities or allergies to laundry detergent, foods products? Did you go on or off the birth control pill or start any medications? So frustrating. I still breakout and it doesnt seem like I will ever have flawless skin like some people so I sympathize. Get some sulfur masks and salicylic acid products. DON'T PICK. (I wish I could take my own advice!)
Good luck.
