大家好,這是小弟在美保版的第二篇文章,還是跟保濕有關喔。

挑選保養品時,一翻到背面,是否成分總讓人眼花撩亂?
今天要介紹的主要研究來自印度: Moisturizers: The slippery road,投稿於 Indian
Journal of Dermatology 。並且以另一篇加拿大團隊研究Moisturizers: What They
Are and a Practical Approach to Product Selection為輔,為大家介紹保濕成分。
保濕成分百百種,但其實可以分成三大類,分別是濕潤劑、鎖水劑和潤膚劑,在這邊幫大
家列出幾個常見的成分,其中某些成分同時屬於兩種分類,一起來看看吧。
濕潤劑(Humectant)
潤濕劑可以把水分從真皮層帶往表皮層,也能吸附外在環境的水分。以下列出幾個較常見
的潤濕劑成分,有些正是上一篇所介紹天然保濕因子的成分喔!
Glycerin 甘油
Alpha hydroxy acid 果酸
Na-PCA 吡咯烷酮羧酸鈉
Hyaluronic acid 玻尿酸
Urea 尿素
Panthenol 泛醇
Aluminum lactate/ Sodium lactate 乳酸鋁/乳酸鈉
Gelatine 明膠
Sorbitol 山梨糖醇
鎖水劑(Occlusive)
當濕潤劑把水分帶到角質層後,若沒有適當的保護是不是很快就蒸發了呢?此時鎖水劑就
要登場了,鎖水劑大部分都是油性成分,能把潤濕潤劑吸收到水份牢牢保護在角質層中,
減緩水分蒸發,以下是成見成分:
Mineral oil 礦物油
Paraffin 石蠟
Petrolatum 凡士林
Stearic acid 硬脂酸
Lecithin 卵磷脂
Cholesterol 膽固醇
Carnauba 巴西棕櫚
Lanolin 羊毛脂
Stearyl stearate 硬脂酸十八醇脂
潤膚劑(Emollient)
潤膚劑可以填補角質細胞間的空隙,讓皮膚更有彈性、更柔軟、更平滑,潤膚劑在使用完
0.5-1小時內會發揮作用,且可持續達將近4小時,以下是常見成分:
Squalene 角鯊烯
Ceramide 神經醯胺
Petrolatum 凡士林
Collagen 膠原蛋白
Castor oil 蓖麻油
到底上述的保濕成分還有什麼其他功效呢?
1. 不用說,當然是讓角質層補水,降低經皮水分散失。
2. 抗發炎: 很多保濕劑可以抑制促炎性前列腺素,有舒緩皮膚發炎的功用。
若美保板的朋友們有想更深入了解哪個特定成分,歡迎在底下推文,小弟會找大部分人有
興趣的成分再做深入介紹。
