Of course they won't work. You're just wasting money on them.
I have to respectfully disagree. I am able to reduce my acne by 95% with supplements along with some diet tweaks, consistent exercise, and moderate sun exposure. I think it's better to say that MOST supplements do not work. If you research deeper into this topic you'll find that with every isolated nutrient, vitamin, compound, etc, comes a list of co-nutrients that it depletes if taken alone. The difficulty in finding success with supplements is compounded by the fact that there is little regulation in the industry for what actually goes into the bottle. At the same time, you have to wade through seas of unsupported articles about "hollistic" health. You also can't overlook that there are multiple forms of each vitamin which have completley different profiles. It's a personal voyage to try to treat yourself but I think its worth it.
