Purpose: The purpose of this study was to examine the overall effects of a natural ingredient Ectoin on moisture content, pore size, and tone of the skin.
Method: Ectoin was used for the production of a foam cleanser, toner, cream, and lotion. Experimental and control groups were provided with cosmetic samples with or without Ectoin, respectively, and instructed to apply them to their face twice a day in the morning and evening over a 4-week period. The data collected in this study were analyzed using the statistical software SPSS 24.0 for Windows.
Results: Regarding oil contents, the control group showed increased oil contents at T- and U-zones, whereas the experimental group showed decreased oil contents at T-zones and increased oil contents at U-zones. Regarding moisture, although moisture contents increased in both the groups after the experiment, the experimental group exhibited a higher increase in moisture content than the control group across all facial areas. The experimental group showed statistically significant increase in moisture content on all facial areas excluding the chin. Regarding transepidermal water loss (TEWL), the control group exhibited increased TEWL values at all facial areas excluding the chin, whereas the experimental group showed decreased TEWL values at all facial areas. Regarding pore sizes, although the control group showed a pattern of alternate increase and decrease in pore sizes, the experimental group exhibited decrease in pore sizes at all facial areas. Regarding pH levels, both groups showed a normal pH range (4.5?6.5) before and after the experiment without any statistically significant changes. Regarding skin tone, the control group showed alternate increase and decrease in melanin, whereas the experimental group showed a statistically significant decrease in melanin on the left and right sides of the face. While both groups showed a reduction in red spots, the experimental group showed a greater extent of reduction in red spots than the control group.
Conclusion: The above results indicate that the cream containing Ectoin as a natural ingredient has a positive effect on skin moisturizing and moisture, and it is confirmed to be a natural moisturizing raw material for cosmetics.
