For the first time ever, I was excited to try an acne spot treatment that contained sulfur, since I've only heard nothing but great things about that specific ingredient. Despite many of the raving reviews, it just didn't work for me. I have hormonal adult moderate acne, and even then I still have pimples every week that never seem to go away. Nothing has worked for me and I thought why not try one more product. Right before bedtime, as per the instructions, I dipped the cotton swab in the separated solution, I didn't shake it before, I then proceeded to dab it on each pimple. It stung the tiniest bit but nothing to stress over. In about 5 minutes or so I noticed a little white dust coming off. When I look in the mirror, I notice that the product was dried up and was coming off my face. I didn't touch it and went to sleep. In the morning, I didn't notice any difference, in fact, one of my pimples turned bigger and redder. I was so disappointed but despite that I continued using the product but alas, no difference. Also, it dries up quickly in the bottle, after a month of use with a frequency of three times a week. Not repurchasing.
