Initial Breakout. Good Or Bad?

So over a week ago now, i began taking a liver purifier supplement named Milk Thistle. It comes in tablet form and i take 3 every day. About 3 or 4 days after taking them, i began breaking out, in areas which i hadn't had acne for a very long time! And im trying to stay positive about it all, because along with the milk thistle, i am also taking Oxy Powder, which is a powerful colon cleansing supplement, and if you ask my toilet, that seems to be working just fine. But what im scared about is, what if this Milk Thistle isnt the cause of my new acne forming everywhere! And forming fast! I mean i havent changed nothing about my diet etc so surely it must be that? Is having an initial breakout a good sign? And how long before it starts to heal? Another thing is, i never used to get whiteheads, but ever since i started taking this supplement, boom! whiteheads forming everywhere! So im hoping this milk thistle and oxy is working, and flushing the toxins out my body, thats why they are showing up all over on my face. Fingers crossed!
