Check out the hormonal acne forum. Do you break out before your period, during it, and/or around ovulation? Yep... This is hormonal acne. From my loooong experience you cannot do much to avoid it. Supplements may work. I use saw palmetto and vitex. My pms is better, but i still break out. I would suggest you to find ways of exterminating the scars and red marks faster. Turmeric in a face mask is awsome. Sudocrem on pimple is helping in shrinking. Also vicks if you have more cystic type of pimples.

I always break out before my period and after.

Always on my jawline or my cheek, which goes away once my period is over, but it sucks and there's really nothing you can do

Advil or ibuprofen every day the week before your period!
