Study of the Efficacy and Tolerance of Light Therapy in Sensitive Skin

Study Overview
=================
Brief Summary
-----------------
Light-emitting diode (LED) light therapy is increasingly used successfully and without adverse effects in diabetic leg ulcer, chronic low back pain, chronic myofacial pain in the neck and in several dermatoses such as acne, Psoriasis, alopecia areata and skin rejuvenation. A Korean study conducted in 2013 suggested its effectiveness in patients with sensitive skin in connection with rosacea, acne, eczema. The objective of the study is to perform a study in subjects with a sensitive skin without associated dermatosis.

Detailed Description
-----------------
The objective of the study is to evaluate the efficacy of light-emitting diode therapy in subjects with sensitive skin and to assess pain improvement, evaluation of improvement in pruritus and evaluation of treatment tolerance.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Efficacy of light therapy | The improvement of sensitive skin symptoms will be measured by the Sensiscale scale | 2 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessment of pain improvement | Pain improvement will be done by self-evaluation of the patients, using a visual analog scale | 2 months | 
| Assessment of improvement in pruritus | The improvement of pruritus will be done by self-evaluation of the patients, using a visual analog scale | 2 months | 
| Assessment of the tolerance | At the end of the study, patients will be questioned about the possible occurrence of side effects listed in the patient's notebook during the 8 weeks of treatment. | 2 months |
