Study of Moisture Content on Various Skin Sites in Different Seasons in Indian Population
Background and Aim: Skin moisture reflects the health and good functionality of the skin, so analysis of variation in skin moisture in baseline individuals may be useful. Results and interpretations of this kind of studies may be useful for the management of common cutaneous disorders associated with decreased skin surface moisture and in the field of cosmetology. Therefore, in the present study, we aimed to measure the variations in skin moisture level with regard to different seasons and skin sites in both genders of healthy Indian volunteers. Methods: Study was conducted on 600 (100 in each season) healthy Indian volunteers of age between 5 and 75 years. Skin moisture level was measured on the forehead, right ocular region, right cheek, right arm, and right palm by digital moisture monitor instrument from skin care company. The measurements were performed for one particular day of different seasons. All readings were measured in percentage. On the day of study, all individuals were placed in controlled environment. Results: Moisture level was found to be decreased in aging skin. Results varied with sites showing higher moisture in the right palm and lowest in the ocular region. Males were hydrated better than females, and temporal variation without uniform pattern was seen. Most differences were small and insignificant. Conclusion: Variation in moisture content will be helpful in quantitative evaluation of absorption, and action of various topical drugs and vehicles in normal individuals. It is also helpful in the field of cosmetology and developing new skin care product which may normalize skin physiology in diseased state.
