Functional Test for a Drink Powder Alone and Combined Use With a Cosmetic Apparatus

Study Overview
=================
Brief Summary
-----------------
This study is designed to observe human consuming effect of a beauty drink powder and combined use with a cosmetic apparatus. It is a randomized, double-blind, and placebo-control study. The target enrollment of subjects is 160 and 4 arms are included, a placebo control, drink powder alone, cosmetic apparatus alone, and drink powder plus cosmetic apparatus. Effects on skin dullness, skin tone unevenness, skin dryness, skin elasticity, wrinkle and fine line are evaluated. Both objective and subjective methods are used for efficacy evaluation. Data are collected at baseline, week 4, week 8, and week 12 after treatment.

Detailed Description
-----------------
In this study, objective parameters are measured by the instruments as following: VisioScan VC20 is used for skin roughness and wrinkle assessment, chromameter CR-400 is used to assess skin color, skin gloss is assessed by Glossymeter, skin hydration is assessed by Corneometer, TEWL is assessed by Vapometer, and skin elasticity is assessed by Cutometer. VISIA-CR and VISIA-7 are used in skin radiation and wrinkle visualization. Clinical assessment is performed by expert visual grading on Skin evenness Skin radiance Skin elasticity Skin smoothness Skin firmness Skin moisture Skin plumpness

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Participants are assigned to four group during the study: a placebo control group, a beauty drink powder group, a cosmetic apparatus group, and a beauty drink powder + cosmetic apparatus group
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: Placebo control group<br>placebo drink powder without active ingredients, 1 sachet per day with 50 ml water for 12 weeks | Dietary Supplement: Beauty drink powder<br>* Beauty drink powder is designed as a oral beauty product to provide benefits to skin<br>|
| Experimental: Beauty drink powder group<br>Beauty drink powder is the test article provide to participants, 1 sachet per day with 50 ml water for 12 weeks | Dietary Supplement: Beauty drink powder<br>* Beauty drink powder is designed as a oral beauty product to provide benefits to skin<br>|
| Placebo Comparator: cosmetic apparatus group<br>This group is designed for a cosmetic apparatus control group without consumption of placebo or test article. Together with the specified cleanser, the apparatus is used for daily facial cleaning, two times in the morning and evening for 12 weeks. | Device: Cosmetic apparatus<br>* This device is designed to let participants to experience brighter, softer, smoother skin and an energizing facial massage. A synergestic effect when combine with beauty drink powder is expected.<br>|
