I break out right before im about to have my period so a good blemish zapper is a necessity. I was pleasantly surprised at how well this blemish stick works! I put it on before bed, and the morning after the blemish I tested it on had definitely shrunken in size. The smell is not particularly good but when it comes to my pimples, smell is the last of my worries (i just want those hideous pimples gone!) I definitely recommend this!
