Skin quality evaluation tools. (A) The Cutometer, which is a reliable and valid instrument that creates reproducible data, was used for the evaluation of skin elasticity. Each measurement was performed in the center of the area of interest. (B) The Corneometer was used as a tool for analyzing the process of scar humidification over time, and the scar surface areas were measured. (C) The Tewameter was used to measure transepidermal water loss, with the measurement of water evaporation based on diffusion. (D) The Mexameter is a tool used to measure melanin (pigmentation) and redness (erythema). Measurement of the melanin and erythema values is based on a source of light with three specific wavelengths whose radiation is absorbed and diffusely reflected by the skin.
