Yes girrrrl! I have too. I noticed I would get multiple little annoying pimples closer to my period, but then after my period had passed, the acne remained on. my. face. It was in specific areas too like on the left side of my cheek, and right on my forehead in between my eyebrows.
I looked it up, specifically where my acne was at, and it said some of the causes of acne in those areas was from a high-fat diet. I've been doing Keto for a while, so I was a little shocked to be getting acne so late in the game, but what I did was continue to drink more water, and I added only a small portion carbs to the mix (my fat consumption was pretty high, and carbs were very low), and my skin did clear up a month later.

First month of keto, i had a few facial pimples and im 65! Just figured it was my body adjusting to macro changes.

I started January 4th. 2-3 weeks in I got an early period (I'm on the pill) and pert near bled out. With that I got two very large, very painful cystic pimples on my face. One close to my nostril and one big ol sucker dead center of my chin. That was weeks ago and it's still healing! I just needed braces and head gear to complete the look. Fingers crossed this next period isn't so brutal.
