One of the things I have tried on my face to clear my acne was Phillips Milk of Magnesia. I applied this substance to my face every night and would let it harden. I would wait for 30 minutes then wash it off my face with lukewarm water. I applied a moisturizer to my face afterwards. I did this for 3 days and started to notice my skin was becoming really dry and irritated. My skin was a little red and swollen because I had to wash my face little longer due to the unwillingness of the milk of magnesia to come off my face. I continued this process for the rest of the week and things continued to get worse. I stopped using this liquid in hopes that my skin would calm down. My skin did calm down, but my acne was still present. I tried milk of magnesia one more time to see if I had given up too soon. I applied the liquid this time only on individual pimples. It definitely worked much better this way. I would definitely recommend Phillips Milk of Magnesia as a spot treatment for acne.
