I use this mask once maybe twice a week. When I first put it on, I was expecting a very heavy mask, like the clay type ones I normally buy. However, this was different. It had a soft silky feel to it. I was still able to some what smile and move my face. So I didn't feel like I was frozen in facial time. When it came time to rinse it off, I had no problems with residue. It came off perfectly and left my skin feeling smooth and moisturized.
