I put it on a few spots (not really pimples) on my face. After a minute of putting it on it stung a lot but apparently it means that it is working. The scent is over powering and it smells, but it goes after about 5 minutes. I had only one actual pimple and I applied it to that too. It made the pimple go down a little but it made the white head bigger. I can't really say whether it worked or not since I have only used it once.
This was the very first mascara I ever tried and it is very good! It makes my lashes look longer and also gives them volume. It's very easy to apply and doesn't clump. I honestly don't know what people are talking about when they say it doesn't make a difference.
