Cutaneous ageing is the deterioration of the skin due to a combination of circumstances (age, exposure to ultraviolet light, smoking, etc.). It manifests itself by the appearance of wrinkles, discolouration of the skin -either lightening or darkening-, dryness, dilated or broken small blood vessels near the surface of the skin (telangiectasia), cutaneous atrophy, irregular thinning of the skin, elastosis (flaccidity), grooves, age spots and other expressions.
