I've been using Kiehl's Blue Astringent Herbal Lotion for over 10 years now and the formula has never disappointed. Whenever there is any sort of blemish or pimple on my face I simply dip a cue-tip in this astringent and dab it on the blemish. Redness and bumps go away and stay away! I recommend using the cue-tip method as it makes my Blue Astringent last over a year!
