Didn't dry out skin but wasn't immediately effective. I prefer a more natural brand for my blemish control bc this formula wasn't as fast acting as I would have liked. Mks is good for some aspects of skincare but for toners I wouldn't say it's the best. To conclude this review, I'd have to say that unless you're looking for a drying method to clear skin of acne the I would recommend choosing a different brand. The price doesn't exactly make sense when comparing it to the effectiveness. In my opnion.
