The Investigators will assess two secondary outcome measures: (1) Histological improvement in skin structure. Skin biopsies from the treated extensor forearm will be taken at study initiation and at the end of the six month study period. These biopsies will be evaluated for: (a) epidermal thickness; (b) fibrillin expression and; (c) pro-collagen I expression. (2) Tolerance and irritancy. Tolerance and irritation assessments will be made by recording the occurrence and severity of signs of erythema and scaling. Safety will be evaluated by recording all adverse events experienced by subjects. Any subject exhibiting adverse events of sufficient severity will be withdrawn from the trial. Completion or withdrawal of subjects from the trial will be noted on the end of study form. All subjects will be monitored for the occurrence of serious adverse events up to, and including, 28 days after their involvement with this study.
