INFLUENCE OF SUNSCREEN PROTECTION FACTOR ON MOISTURE, OIL, AND PH OF THE SKIN

Using sunscreens with a different sun protection factor (SPF) has been advocated by many health care practitioners as a means to protect the skin from damage caused by ultraviolet (UV) radiation from sunlight. There is a need to better understand the changes that occur in the skin's Biophysical parameters following the application of sunscreen products. The main objective of this study was to know the influence of sunscreen with various SPF on some skin biophysical parameters. In the present study, we investigated the effects of sunscreen on skin moisture, oil, and pH in 20 subjects. Skin conditions such as moisture, oil, and pH were measured and compared before and after the application of sunscreen. Statistically significant differences were observed in skin moisture and pH. There were also inter-individual differences but, with respect to gender differences, only skin pH was significantly different. According to the study results, applying sunscreen with SPF 50 on the skin was found to have a better profile of biophysical parameters than the sunscreens of low SPFs. Therefore, it can be concluded that a chemical sunscreen with SPF 50 is probably the optimal level to protect the skin from the damage of exposure to the sun's UV rays
