Methods and apparatuses are disclosed for modifying images of skin so as to reduce or enhance the appearance of component pigments, such as melanin and hemoglobin. A diffuse reflectance image of skin, such as a cross-polarized contact dermoscopy image, which conveys information regarding subsurface features of the skin, is processed so as to extract pigment distribution information, which is then used to correct the diffuse reflectance image, such as by reducing the appearance of melanin to allow better visualization of hemoglobin-related structures, such as vasculature. Alternatively, the diffuse reflectance image can be corrected so as to reduce the appearance of hemoglobin to allow better visualization of melanin-related structures.

Provided is a spectrum processing apparatus for removing noise, caused by a change in temperature, from a spectrum. The spectrum processing apparatus includes: a temperature modulator configured to perform modulation of a temperature of an object; a spectrometer configured to obtain a first spectrum based on the temperature of the object that is changed by the modulation; and a spectrum processor configured to extract a temperature change vector based on the first spectrum, and to correct a second spectrum based on the extracted temperature change vector.

Provided is an adhesive tape for collecting skin indigenous microorganisms, the adhesive tape being capable of providing improved collection yields of skin indigenous microorganisms on a skin surface. This adhesive tape is for collecting skin indigenous microorganisms, is used to collect skin indigenous microorganism on a skin surface, and comprises a base material and an adhesive layer provided on at least a portion of a surface of the base material, wherein the adhesive layer contains an adhesive, and the adhesive contains a rubber adhesive. The adhesive tape has an adhesive strength of 10.0 N or more when a 12 mm-wide test piece thereof is pressure-bonded to a Bakelite plate by one reciprocation of a 2 kg roller and then measured for adhesive strength at a pulling speed of 300 mm/min and a pulling angle of 90° according to JIS Z 0237: 2009, and the adhesive tape has a peel strength of 0.25 N or more when a 12 mm-wide test piece thereof is measured using a silicone-treated fine paper sheet as a release sheet and measured for peel strength at a pulling speed of 300 mm/min and a pulling angle of 180° according to JIS Z 0237: 2009.

The present disclosure relates to optical methods and devices based on pulsate behavior of blood and optical absorption spectroscopy to measure the level of water and/or other substances or compounds, such as an alcohol or lipid, in the blood and the tissues surrounding blood vessels and arteries.

An information processing apparatus includes a memory and at least one processor. In the memory, a program is stored. The processor is configured to execute the program stored in the memory, and generate prescription data for skincare of a skin based on history data of an index value representing change in blood flow before and after treatment. The index value is calculated based on a first skin image and a second skin image. The first skin image is obtained by imaging the skin before a blood flow enhancement treatment, and the second skin image is obtained by imaging the skin after the blood flow enhancement treatment.

An example computer-implemented method for analyzing skin of a user comprises requesting, via a graphical user interface (GUI), visual media including a face of the user, processing the visual media to generate information for each of a plurality of skin conditions of the face of the user and the information comprises a score per each of a plurality of zones of the face of the user per each of the plurality of skin conditions of the face of the user, mapping the score to a severity level associated with the plurality of skin conditions, and for each of the plurality of skin conditions, the GUI overlaying computer graphics at locations onto the visual media corresponding to the plurality of zones of the face of the user. The computer graphics are depicted with a color associated with the severity level for the skin condition at each of the locations.

A method of determining a cosmetic skin attribute of a person is provided. The method includes obtaining a color channel image of a person's skin, analyzing the color channel image with a computer using entropy statistics to obtain an entropy value, and then determining a cosmetic skin attribute for the person based on the entropy value.

Methods and apparatus for detection of tissue damage in users using a PPE device for an extended period of time are disclosed.

A skin cleanser includes a surface, such as a silicone surface, with at least one textured portion for transmitting vibrational tapping to the skin. The skin cleanser includes at least one oscillating motor for generating the tapping motion to the skin. The textured portion in touch-points or a wave that transmit the tapping motion to skin in contact with the to portions. The touch-points may include thicker and thinner formations of the touch-points to provide firmer or softer vibrations to the skin. The touch-points are within about 0.5 to 2.5 mm in diameter. One configuration includes multiple oscillating motors configured to provide different vibration frequencies at around 50-300 Hertz and operable simultaneously.
