Verification of air brush effectiveness using cosmeceutical ingredients

Abstract

BackgroundThe development of the beauty industry has been accelerated by the combination of the basic desire of humans to look beautiful and the trend of the age in which the down-aging phenomenon is caused by an aging society. Previously, therapy, which has been provided by experts, has now expanded and changed its category into everyday home care. Thus, skin care devices became common and widespread. Also, public attention has been focused on functional cosmetics such as whitening and wrinkling improvements of a home care product. However, the results of validation of the effectiveness of functional components and the use of skin care devices are rare.MethodsMiddle-aged women were asked to apply 3 mL of ampule containing niacinamide 2% and adenosine 0.04% to the face twice a day, once in the morning and the other in the evening, for 4 weeks. The control group (C) was asked to apply using hands while the experimental group (E) was asked to apply using airbrush.ResultsThe moisture content of the entire face has increased in all clusters, resulting from a combination of the moisture content of the niacinamide and the increase in the collagen content of the adenosine. L* was increased in all groups, but only E showed significant results. a* was increased in C and showed a significant decrease in E only. b* decreased in group C and increased in group E. The overall size of the wrinkles, the depth of the wrinkles, and the width of the wrinkles showed significant improvements in all groups, with higher rates of improvement in E.ConclusionsThis study produced verification results on whitening effects of niacinamide, wrinkling improvement of adenosine, and the usefulness of air brushes. Previously, dermal absorption studies on soluble ingredients of cosmetics were limited to iontophoresis, while various methods of study design on the dispensing and physical effects of fine particles were expected. It also recommends a research design approach that is practical for home care, rather than approach using a professional program on the usefulness of skin care device.Trial registrationKorea National Institute for Bioethics Policy, P01-201711-13-002, registered 16 November 2017, http://public.irb.or.kr/.
