I just love doing foot mask peeling! This was so easy to use. I was skeptical of its effectiveness after watching some videos about it. I followed a suggestion given of massaging the cream onto the feet while wearing the plastic sock. I chose to wear my regular sock on over the plastic ones for a better experience of walking around the house during the 90 minutes wait time. Skin peeling was evident after a few days and very much after a week. I chose to use a loofah to scrub peeling skin off after a week. I do not recall when my feet last felt so smooth. I suggest that if you plan on doing this process in preparation for a special event or vacation, do it at least 2 weeks in advance to give plenty of time for peeling to be done. I highly recommend Melzu. I was surprised for such a major effect from so little work. It's one of those great things that come in small package.
