I will tell you right now that this is a machine that best skin lightening cream, and I am reluctant even to mention it because it will sound self-serving. But honest to God, I have used this device almost every day for fourteen years, and I truly feel it has arrested the aging process on my face. The Face Master uses a micro current that pumps up the muscles under the skin to hold up the structure and, thus, keep the skin from sagging. My partner in this venture, Dr. Peter Hanson, likens aging skin to an old barn with a sagging roof. If you were just to replace the shingles, the roof would still be sagging.
