I've used those tablets for one month long ago. It really didn't do much.
To answer your question--- a lil fact---
Although it is approved by the FDA, homeopathic products are not put to the same standards as prescribed or OTC drugs. So-- homeopathic products aren't required to be proven effective in order to be marketed.
But i guess it wouldn't hurt to just give it a try. I really didn't see much improvement in my acne. Hope this helps!
