The study will start after researcher has been granted the Ethic Committee Approval. The process of subject recruitment and clinical data collection will take place at the Outpatient Department (OPD) while photograph taking and skin measurement will take place at Laser Center and Bioengineering Department, respectively. All bioengineering instruments will be operated under the climate controlled environment; i.e, at temperature 20+/-2 degree Celsius and 50+/-2 % of relative humidity. A subject must get acclimatized to the ambient atmosphere for at least 30 minutes. The clinical data, skin barrier function, the quality of life, subject's satisfaction scale will be collected at the first day (D0, as baseline) and 4th week after finishing the test product (Wk4).
