Abstract

Recently, interests in mask-type skin care devices using light-emitting diodes have been increasing and optical stimuli at certain wavelengths have been known to have various therapeutic effects, such as skin whitening, acne treatment, elasticity and wrinkle improvement by controlling the exposure to wavelengths of light and irradiation time. In particular, light sources of different wavelengths are applied in masks for the purpose of suppressing skin aging, inducing cell proliferation, and alleviating skin inflammation. In this paper, we developed a light-emitting diode control system that is actively used in skin regeneration masks using a microcontroller. Optical stimuli with different manners were applied to skin fibroblast cells in a single or complex wavelengths, and then confirmed how they are effective in the cell differentiation. In addition, we found a specific wavelength that has a positive effect on cell proliferation rates, and confirm the effectiveness of cell proliferation by image processing based quantitative analysis.

최근 발광다이오드를 이용한 마스크 형식의 피부 관리기에 관한 관심이 증가하고 있으며, 특정 파장의 광학적 자극은 노출 광량 및 파장대, 광선 조사 시간을 조절함으로써, 피부 미백, 여드름 치료, 탄력 및 주름 개선 등과 같은 다양한 효과를 보인다고 알려져 왔다. 특히, 피부 노화 억제, 세포증식 유도, 피부의 염증 완화 등을 목적으로 하는 마스크의 경우 각각 다른 파장의 광원이 사용된다. 본 논문에서는 마이크로컨트롤러를 사용하여 피부재생 마스크에 활발하게 사용되는 발광다이오드 제어시스템을 개발하였다. 단일 또는 복합적으로 피부 섬유아세포에 인가하여, 세포의 증식에 어떠한 효과가 있는지 확인한다. 또한, 세포증식률에 긍정적 효과를 보이는 특정 파장대를 찾아 다양한 자극에 기인한 세포증식 효과를 확인하고, 영상처리를 활용한 정량분석법을 제시하여 그 효과를 평가하였다.
