I've tried this before but I wouldn't recommend it.
I bought it a long time ago, but I forgot to mention it in my previous posts.
I fell for the advertising too, I was younger & stupid so I bought the duo & used them & never saw a difference whatsoever.
It smells weird & it's oily!
It'll also make your face yellow afterwards if you use too much.
However, I uh, didn't give it enough time to truly see results & I'm not sure if I was doing right, but still, I wouldn't recommend it.
Anything that promises stuff like that are usually scams & I regret that I didn't realize that when I first got some but my acne was worse back then so I wanted to try it.
I honestly can't say whether it would have worked for me or not, but I doubt it.
I can't test it out again b/c I threw it away when I cleaned out my cabinet.
But whatever you decide to do, do it only if you really want to & if you can afford it.
Not that this stuff is that expensive, but there should be better stuff out there than this.
Just my opinion though.
The reason this probably wasn't in other posts is b/c it most likely sounds like a scam & promises too much so I guess lots of people simply wouldn't bother w/ it.
Good luck in whatever you decide = )
