3 - A duly looking skin
Dead cells accumulation leads to an irregular and rough skin. Due to the harsh surface, the light will not be reflected homogeneously, revealing a duly and grayly skin.
This phenomenon is mainly observed in friction areas (elbows, knees, and heels).
Medium to darker tones are special and require particular attention. An appropriate treatment is necessary, as well as UV protection to avoid redness and dark spots.
