An Efficiency of a Moisturizer Containing Licochalcone A, L-carnitine and 1,2-decanediol With Adapalene Gel in Acne

Study Overview
=================
Brief Summary
-----------------
Acne is an inflammation of sebaceous glands and follicles. Applying topical treatments such as adapalene gel may cause irritant adverse effects. Hence, using a moisturizer is another way to protect or relieve this undesirable event. Moisturizers that have anti-inflammatory property could reduce irritant effects, emergent from using topical treatment and also reduce severity of acne. Research teams chose an adapalene gel to act as topical treatment for curing acne. It has anti-inflammatory and comedolytic effects and has fewer side effects than other groups of topical retinoic acids. However, peeling skin, redness skin, tingling sensation or itching sensation may occur if they are continually used for a long period. Thus, for the purpose of studying the efficacy of moisturizer containing licochalcone A, L-carnitine and 1,2-decanediol in reducing irritant effect of using adapalene gel (Licochalcone A has anti-inflammatory effect, L-carnitine decrease sebum production and 1,2-decanediol has anti-bacterial effect).

Detailed Description
-----------------
The investigators team research with patients by separate patients into 3 groups and compare among each other. In the first group use only adapalene gel, the second group use adapalene gel with moisturizer containing three substances mentioned above, and the last group use adapalene gel with placebo moisturizer. To compare outcomes among 3 groups, the investigators will measure degree of redness, scale, oily face, moist, number of acne, quality of life, and satisfaction after using moisturizer.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Reduction of Undesirable Effects | Undesirable effects were evaluated from skin's condition/signs(erythema, dryness and scaling) are evaluated by dermatologist. (none; mild; moderate; severe) and subject interview/symptoms(stinging/burning and pruritis) are evaluated by participants.(none; mild; moderate; severe). There were assessed at 2nd week, 4th week, and 8th week. The worst score of each parameter which was defined as the worst local tolerance score is demonstrated and compared among 3 groups as shown. | 2nd week, 4th week, and 8th week | 
| Skin Tolerability: Skin Sebum Content and Skin Hydration | Skin tolerability was assessed by measuring the skin surface sebum content, skin hydration with the Sebumeter SM815 and Corneometer CM825, respectively | Skin tolerability was assessed at baseline and week 8. The changes of skin tolerability between baseline and 8th week of the 3 groups were compared. | 
| Skin Tolerability: Transepidermal Water Loss (TEWL) | Skin tolerability was assessed by measuring TEWL with the Tewameter TM300 | Skin tolerability was assessed at baseline and week 8. The changes of skin tolerability between baseline and 8th week of the 3 groups were compared. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Reduction of Severity of Acne | Evaluation from mean counts of inflammatory, noninflammatory, and total acne lesions at baseline, and at 2, 4, and 8 weeks Total acne lesions = inflammatory + noninflammatory acne lesions Reduction of lesions counts are considered to be a better outcome | baseline, 2nd week, 4th week and 8th week | 
| Reduction of Severity of Acne: Acne Severity Index (ASI) | The ASI score was calculated from the number of papules + (2 x pustules) + (comedones/4) Decrease of ASI score are considered to be a better outcome | baseline, 2nd week, 4th week and 8th week |
