This study examined the effectiveness of micro-current stimulation (MCS) to improve the facial skin qualities by performing clinical test. The MCS is generally known that provide healing response in the damaged tissue and pain relief through activating the adenosine triphosphate (ATP) and protein synthesis. In here, we can hypothesize that the improvement of facial skin qualities may occur due to MCS, since the induction of micro-current from outside may enhance the cellular activity according to ATP activation. From the clinical test, our results showed that a variety of evaluating categories, which is able to assess the skin qualities, significantly enhanced due to stimulation of micro-current after 7 and 14 days. Therefore, we can estimate that MCS in human facial skin may be effective to improve the skin qualities.

In this paper, we propose a method about reducing facial blemishes using Morphological Operation. First, we detect skin region using pixel data of RGB's each channel image. we create histogram of skin region R, G, B channel and save 3 pixel values that are high frequency pixel value in each channel. After than, we find facial blemishes using Black-hat operation. The pixel value of facial blemishes changes average of its pixel value, 8-neighborhood pixel value and high frequency pixel values. And the facial blemishes pixel is blurred with median filter. The result of this test with facial pictures that have facial blemishes, we prove that this system that correct the face skin using reduction facial Blemishes is more efficient method than correct the face skin just using lighting up.
