| Résumé : |
Age spots, also Lentigo senilis, are small, localised, sharply circumscribed sites of hyperpigmentation of the skin. Contrary to freckles, which are due to an UV-induced increased, but reversible production of melanin, lentigines are caused by local hyperplasia (cell proliferation) at the basal layer of the epidermis. Melasma, another symptom of hyperpigmentation and of aesthetic concern to Asian population is characterised by diffuse patches of brownish colour, often induced by hormonal imbalance ('pregnancy masks') and sometimes reversible. |
