Abstract: The present invention relates to a device and a method for measuring skin changes caused by blue light. A device for measuring skin changes caused by blue light according to one embodiment of the present invention comprises: at least one light source for irradiating light of a blue light band at different light amounts to a plurality of test areas set on a skin area to be tested; and a control unit for detecting a minimum pigmentation point among the test areas and calculating a light amount of the corresponding test area as a minimum pigmentation dose (MPD) for blue light. In addition, the present invention relates to a blue light irradiation device for irradiating a plurality of blue light beams in order to measure skin changes caused by blue light.

Abstract: Embodiments relate to a skin diagnosis system and method based on image analysis using deep learning, containing: a face recognition model that derives shape or location information of a facial structure by recognizing feature points capable of identifying an individual in an acquired face image; a de-identification model that de-identifies a face image on the basis of the shape or location information of the facial structure such that personal information of an analysis target cannot be identified; and a plurality of artificial neural network models for each of at least one item among diagnoses for wrinkles, pigmentation, pores, erythema, and aging.

Abstract: The present invention relates to a wrinkle measurement apparatus and a wrinkle measurement method. The wrinkle measurement apparatus according to one embodiment of the present invention comprises: a surface direction compression part including first and second contact parts arranged at a preset gap while coming into close contact with the skin, so as to compress the skin in the direction of the surface thereof; and a wrinkle measuring part for measuring skin wrinkles in at least two states among pre-compression, mid-compression and post-compression.
