A woman whose skin suddenly broke out in severe acne covering her whole face has shared candid selfies of her condition online. Mariia Bilenka, 22, from Kiev in Ukraine , had clear skin in the autumn of , despite having had trouble with acne as a teenager.

She does not know for sure why her skin broke out so drastically, but believes the stress of moving away from home and starting a new life played a part. There is no evidence stress is a direct cause of acne, but it may influence hormones which are linked to the onset of acne in adult years, and also trigger outbreaks in people who already have bad skin. It was in the worst condition it had ever been in my life.
