Detoxing is probably what it is. Hormones are stored in fat so more are being released into your blood. Stick with it though. I always had skin problems. They got worse when I first started LCing but after about a while my skin became flawless. This was amazing for me as I always, always since i was 11 had at least 2 spots on my face at any time.

Stick with it, believe me it will help your skin.
