Placebo Controlled Efficacy Evaluation of the Hydrolyzed Collagen Peptide In Adult Females

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate the contribution of hydrolized collagen products to elasticity, hydration and roughness of the skin of female volunteers. Safety and tolerability of the product is the other objective of this placebo-controlled, randomized study.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change on skin elasticity | Measurement of elasticity based on the stress/deformation method through skin suction by using an instrument specifically developed for assign skin health. | 3 months | 
| Change on skin hydration | Measurement is based on the hydration of the stratum corneum through the capacitive method by using an instrument specifically developed for assign skin health. | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change on skin roughness | Measurement is based on capturing skin images by using an instrument specifically developed for assign skin health. | 3 monhs |
