In various embodiments, a method for determining a homogeneity of complexion is provided. The method may include provision of a digital image on which skin is portrayed and which is parameterized in a color space which is defined by a parameter set in which one of the parameters is a hue, identifying and/or defining at least one skin examination area in the transformed image, calculating a hue distribution in the at least one skin examination area, and determining at least one homogeneity value for the complexion based on the calculated hue distribution.

A system with a deformable membrane for speckle mitigation. In some embodiments, the system includes a laser for producing laser light; a photodetector for detecting the laser light after interaction of the laser light with a sample; and a silicon deformable membrane, for modulating the phase of the laser light.

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 includes touch-points or a wave that transmit the tapping motion to skin in contact with the textured 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.

Example aspects of a volatile organic compound detection device, a wearable health monitoring device, and a method of monitoring a user's health are disclosed.
