The one I actually use is the Ultra Acne +Marks Wash and Mask. Probably the same thing listed here, being as how companies tend to change their packaging and names over and over. See it every day in the job I have, and it's the same thing but with more words added. I only use it once a week or so as a mask because otherwise it would seriously dry my face out. But I love that it's thick enough to be used as a mask, and I like that it feels like it's working the second it touches my face. Afterwards, my skin feels a little tight but squeaky clean. Effectiveness Tingly, warm sensation lets me know it's doing it's job and afterwards my skin feels clean and smooth. Ease of Application It is thick, but not so thick that it doesn't spread well. Perfect thickness. Convenience It takes a little to get it off. I can't just splash water on my face to get it off, otherwise I would be wasting a lot of time and water. To get it off quicker, I have to use a wash cloth and every couple of swipes, I have to rinse out the wash cloth. Side Effects It will dry your skin out in a hurry if you use it every day.
