I began a new routine 3 months ago that kept my face completely clear. In the morning I use Clean & Clear astringent and CeraVe moisturizer, and in the evening, the new part of the routine, I use Purpose gentle cleanser and Sea Breeze astringent. After starting this I was pretty much clear for 3 months, with one occasional pimple every month or so. However, last week, after a long, sleepless night of studying for an exam, I got a pimple on my left cheek. I figured ok, whatever, and dabbed some tea tree oil and moved on. But then I started forming new pimples on each successive day, I even got a pimple in a section of my cheek that never breaks out. Absolutely nothing changed with my diet or anything, what happened? Does my cleanser suddenly not work anymore?
Some people respond terribly to any oil. Check out the user reviews here for "Oil-Cleansing Method". Tea Tree is a strong disinfectant for sure, but you already have that element with your astringent. Using both might be excessive for your skin. Hope that you clear up soon!
