老年人常見的皮膚問題有哪些？ 外表和紋理變化 皮膚具有不斷自我再生功能。新細胞形成於底層皮膚，然後緩慢上移。抵達皮膚表層時細胞死亡，每天脫落更新。這種細胞再生過程會隨著衰老而日漸緩慢。「死亡細胞」層滯留在皮膚表層的時間會延長，皮膚因此而顯得黯淡無光。從而引起皮膚粗糙、起鱗。 皮膚的支撐結構和彈性隨年齡增長而減弱。皮膚下垂，皺紋浮現。 老年性紫癜 老年人的皮膚更薄，容易破裂。 血管也容易破裂造成瘀傷，稱為老年性紫癜。 老年性紫癜常見於前臂。這種症狀的原因是玻尿酸的量減少，玻尿酸是一種維持皮膚充盈度（和功能性）的必要物質。 出現這種現象並不代表缺少維他命或患有出血性疾病。 皮膚受傷後會慢慢癒合。 老年性紫癜 乾燥症/乾性濕疹 由於皮膚的油脂成份隨年齡增長而減少，皮膚變得乾燥而容易脫皮。 皮膚乾燥導致發癢。常見為乾燥和緊繃感。 乾燥皮膚的表面粗糙且極易脫落或起鱗。常見於背部上方和四肢，尤其是脛部。有時乾性濕疹出現在乾燥的皮膚區域。表現為邊界模糊的鱗狀圓形紅斑。有時外觀表現奇特，呈現紅色鱗狀裂紋，組成不規則的網狀，如同破裂的瓷器一樣。 皮膚感染/寄生蟲侵襲 細菌感染：乾燥皮膚上的裂紋容易使細菌入侵，造成表皮感染。 疥瘡 疥瘡是一種由疥蟲引起、極癢的皮膚感染疾病。 居住於擁擠環境的老人易受這種寄生蟲侵擾。 有時整個身體都可能結痂和起鱗（挪威疥）。 疥蟲 癬感染 1. 老人的指甲和皮膚常發生癬感染，尤其是足部。 2. 指甲癬感染表現為指甲變色和增厚。 3. 足部癬感染症狀除了起鱗外，還可能泛紅和起水皰。 顏色變化 常表現為外觀似雀斑的棕色斑點。 但是比雀斑更大、更不規則。這些斑點稱為曬斑（肝斑）。有時也稱為老年性雀斑。 這是由日曬造成的皮膚損傷。 如果這些雀斑變大增厚或結痂，應諮詢醫師。必須排除皮膚癌的可能性。 老年性雀斑可以透過冰凍、電燒或塗抹特定化學品的方法輕鬆去除。 老年人的皮膚色素細胞的活性降低，所以膚色可能發黃。 水皰疾病 老人患水皰疾病的原因有很多。 常見的水皰疾病是帶狀皰疹： 這是年幼時所患水痘（帶狀皰疹病毒）再次激活而導致的反應。 表現為頭部或身體一側或某個肢體出現一片水皰。 可能伴隨劇痛。 帶狀皰疹 水皰問題也可能是由於免疫功能紊亂而導致的反應。這種疾病的常見病症是大皰性類天皰瘡，患者的泛紅或正常皮膚上起很多大水皰。這種病症往往需要強效藥物加以抑制。 非癌變皮膚增生 老年人可能患上許多不同類型的良性皮膚增生。包括： 脂漏性角化症（粗糙的棕黑色斑點） 櫻桃狀血管瘤（光滑的紅丘疹）（Campbell-de-Morgan 斑） 皮脂腺增生（脂腺組成的黃色丘疹）。 良性皮膚增生不需要治療，但是癌變增生應儘早去除，以防擴散到其他身體部位。 如有懷疑，請諮詢醫師。您的皮膚科醫師可告知您的皮膚增生是良性還是惡性。 脂漏性角化症 癌變皮膚增生 年輕時期過度日曬的老年人可能患上稱之為日光性角化症的癌前期皮膚增生和基底細胞癌及鱗狀細胞癌等皮膚癌。…

Pathogenesis of melasma (chloasma) (pregnancy mask) remains unknown. Treatment which is effective on the epidermal component of the pigmentation acts by the following mechnisms: inhibition of melanin synthesis blockage of melanosome transker from melanocytes and keratinocytes (niacinamide). Solar eviction and photoprotection are a crucial element in the treatments. The gold standard in the treatment of…
