冬季保養：臉跟身體要分開看！5 大關鍵成分一次懂

先說結論：冬天保養不能只靠「保濕」
臉跟身體的皮膚結構不同，需要的保養方式也不同。
想真正改善乾燥、脫皮或敏感，需要：
✔ 補水
✔ 鎖水
✔ 修復
✔ 改善屏障
✔ 選對有效成分

① 臉 vs 身體：冬季需求完全不一樣

臉部皮膚

• 薄、皮脂多、較敏感
• 容易乾燥、刺痛、脫皮
• 適合：質地輕盈、保濕力強、不致痘、不過油的產品

身體皮膚

• 厚、油脂少
• 冬天更容易粗糙、乾裂、癢
• 適合：厚霜、滋潤度高、能長效鎖水的乳液

→ 重點：臉要精準溫和，身體要大量滋潤；清潔和防曬兩者都很重要。

② 冬季必備的 5 大有效成分（含機制、功效、適用族群、注意事項）

1）神經醯胺 Ceramide

作用：補「皮膚磚牆」間的脂質，強化屏障、鎖水。
功效：改善乾燥、脫屑、粗糙，加速受損肌恢復。
適合：乾肌、敏感肌、異位性皮膚、屏障受損者。
博士叮嚀：含量太低效果不佳；搭配膽固醇＋脂肪酸比例更好。

👉 用在：臉 和 身體都很適合，是冬季保濕王者。

2）玻尿酸 Hyaluronic Acid

作用：強效抓水，大分子保表層，小分子補淺層。
功效：使皮膚飽滿、水嫩、平滑，並減少細紋。
適合：所有肌膚（包含油肌、痘肌、敏感肌）。
博士叮嚀：空氣太乾時需搭配乳霜鎖水，不然反而可能變乾。

👉 優點：保濕立即感最強。

3）維他命 B5（泛醇）Panthenol

作用：吸水＋強化屏障＋加速小傷修復。
功效：鎮定、舒緩乾癢紅腫，改善敏感。
適合：敏感肌、乾癢、濕疹、刺激後泛紅、嬰幼兒肌。
博士叮嚀：很安全，但屬輔助型，單靠它不能抗老或美白。

👉 優勢：溫和度高、舒緩力強。

4）外泌體 Exosomes

作用：像細胞「信使」，啟動修復、抗炎、促進膠原蛋白。
功效：提升彈性、水分、幫助術後修護、改善暗沉與細紋。
適合：醫美術後、成熟肌、需要深度修復的人。
博士叮嚀：研究仍少、價格高、保存要求高、產品良莠不齊。

👉 屬進階成分：有效但不適合每個人天天用。

5）胜肽 Peptides

作用：像指令訊號，促進膠原蛋白、放鬆表情紋、提升彈性。
功效：改善細紋、鬆弛、肌膚粗糙；長期使用效果更明顯。
適合：想抗老的 30+、敏感但不能用酸類或 A 醇的人。
博士叮嚀：滲透度有限、見效較慢、需耐心長期使用。

👉 優勢：溫和抗老，不刺激。
