Brief Summary:
Photoaged or chronically sun-exposed skin is characterised by a number of clinical features including fine and coarse wrinkles. The pathogenesis of wrinkle formation has yet to be determined fully but recent work suggests that ultraviolet radiation-induced reduction in dermal fibrillin (in the form of fibrillin-rich microfibrils) is important. Using an extended in vivo patch test assay, it has been identified that skin care products - currently marketed by CG Skin Ltd - increase the deposition of these microfibrils in photoaged dermis and hence have the potential to repair photoaged skin. The Investigators now propose to examine the efficacy of the product in randomized, placebo-controlled clinical trial.
Detailed Description:
Subjects who satisfy the inclusion/exclusion criteria and who have given their written, witnessed, informed consent will be admitted to the studies. Subjects will be clinically assessed (fine wrinkling, coarse wrinkling, mottled hyperpigmentation, sallowness) and clinical photographs taken prior to instruction on the use of the allocated cream by the study Investigator (product or placebo). Product will be applied daily to the entire face and dorsum of hands, including the wrists and extensor forearm, for six months. Successive follow-up visits (3 visits over a 6-month period) will be made to assess efficacy and safety. Subjects will be randomly allocated to self-treatment with either product or placebo cream using a computer generated code (Research Randomizer; www.randomizer.org).
The primary outcome measure will be treatment efficacy; this will be assessed by the study Investigators as changes in the clinical parameters of photoaging (fine wrinkles, coarse wrinkles, mottled hyperpigmentation, sallowness).
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 Any subject exhibiting adverse events of sufficient severity will be withdrawn from the trial.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.
The trial will be conducted according to the recommendations of ICH GCP and those of the Declaration of Helsinki, only after approval of the study has been obtained from the relevant Research Ethics Committee.
