This is a rich cream formula that is especially effective on areas that suffer from the severest dry skin - hands, feet, knees, elbows and cutical areas. It is specially formulated with magnesium ascorbyl phosphate (stabilized vitamin C) and with the amino acid, L-ergothioneine, to meet the particular needs of mature skin. These two ingredients have been shown to boost the cell's ability to utilize ATP which is the primary energy source for all cellular metabolism. With this formula, skin cells receive an extra energy boost that helps them utilize the gamma-Linolenic Acid present in borage oil. If used on a regular basis, the effect is cumulative and will result in long term improvement.
