Purpose: The purpose of this study is to reemphasize the validity of developing a small sized skin-care tool that is convenient to use in common households, and to objectively prove whether an at-home skin-care device with personal mobility can have the positive effects on skin (especially whitening effect) and psychological satisfaction.
Methods: This study required the test subjects to use at least two functions including hypoallergenic peeling function and dead skin cell care for more than once a day. Afterward the changes in skin whitening was measured (changes in skin brightness and tone) and survey responses were collected. The study was conducted for 8 weeks’ period, and the skin color and tone was measured twice, before and after the study. The survey was taken once in a form of 5 point Likert scale.
Result: First, measuring changes in skin tone after the use of the product showed that in 66% in age group of 18 to 19, and 83% in age group of over 20, the product was effective. So, in total 79% experienced increase in brightness of the skin. Among the 29% of the subjects that showed decrease in skin tone using the toolkit, some admitted that there was an error during self-measurement process, and some expressed that with naked eyes the skin appears to be brighter after using the product. This may be due to changes in colors of the skin that was not part of the measurement. Secondly, in the survey assessing the psychological satisfaction from using the product, test subjects gave 79% to 100% positive responses.
Conclusion: The study confirmed that an at-home skin-care device has a positive effect on the user’s skin beauty (especially whitening effect) and psychological satisfaction of the user.
