16-Week Randomized Split-Face Efficacy Study of Cosmetic Formulations in Photoaged Pigmented Skin Subjects

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to determine the efficacy of seven different formulations currently marketed and commercially available cosmetic products on skin tone evenness, post-inflammatory hyperpigmentation, and discrete pigmentation in females of Fitzpatrick skin types IV-VI.

Detailed Description
-----------------
This is a single site, double-blind randomized, split face, efficacy study. All subjects will receive a cleanser, Day Cream/sunscreen, and two treatment products. The treatment products will be applied in a split face fashion including behind the ear. Local volunteer subjects will be enrolled such that a total of eighty-four (84) subjects will complete the study; with 24 subjects completing in each treatment. Each subject will receive a cleanser, Day Cream/sunscreen and two treatment products as per the randomization. Subjects will use the cleanser twice daily, Day Cream/sunscreen in the morning, and the treatment products as specified after cleansing in the evening, for a period of 16 weeks. Clinical assessments, non-invasive instrument measurements and photographs will be completed at baseline and weeks 4, 8, 12, and 16. Biopsies will be taken at baseline and Week 16.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Skin Tone Unevenness | Using a 0-9 scale where 0= even tone and 9=severe blotchy hyperpigmentation. Subjects will be recruited with mild to moderate skin tone unevenness. The goal is to show improvements by dermatologist assessments and photography | Every 4 weeks up to 16 weeks | 
| Skin Firming | Using a non-invasive clinical instrument (Cutometer) skin elasticity will be measure of the facial cheek | Every 4 weeks up to 16 weeks | 
| Skin Moisture | Using a non-invasive clinical instrument (SkiCon) skin conductance will be measure of the facial cheek | Every 4 weeks up to 16 weeks | 
| Skin Oiliness | Using a non-invasive clinical instrument (Sebumeter) skin conductance will be measure of the facial cheek | Every 4 weeks up to 16 weeks |
