This is so bizarre! I have PCOS so I get AWFUL acne all over my body the day of my menstrual cycle. Well todays the day and there is 0 acne. Can fasting really prevent acne!?? Because the last 2 days my skin has been clearer than ever
Didn’t think skin could clear so quickly without any ointment .. and to not develop any acne today of all days is unusual .
Fasting reduces sebum production, a compound vital to keep skin healthy but which also has the drawback of producing acne for a lot of us.
Edit: Sources“Some studies found a strong relationship between a fasting type diet and acne in human adults and young subjects. In fact, during the period of caloric restriction, sebum level was found to be reduced by 40%, which influenced the degree of acne severity [64,65]”

I moved to a new state and my skin freaked out and I then had bad acne for about two years—nothing helped. Then I did a four-day fast and my skin completely cleared and stayed cleared for six months!! Obvious ymmv but it was the best unexpected side effect!
