I didnt see any acne with beast, but I believe that it is kind of like hair loss. Those that are prone to it will tend to see that side come out more often.
The only side I had with beast was some minor back pumps, but I took several cycle supports. From liver support, lipid stabil, taurine to help with back pumps, and some others.
It seems those that have the worst sides are also those that are the least prepared for their cycles.
