產品功效:植物鞘氨醇為角質層中的主要成分,具有防禦阻止細菌入侵及避免水分散失的重要功效。植物鞘氨醇具有多種生理學的功能,例如可以恢復皮膚基本的彈力結構、消炎功能、抗菌功能及控製細胞生長和分化功能,同時也能促進神經醯胺的合成,進而延緩皮膚的老化現象。本產品與動植物來源的植物鞘氨醇不相同,是由酵母菌經過醱酵製成,因而不含有害因素,故使用安全,且因結構與人體皮膚的鞘磷脂相近,所以容易被吸收利用。植物鞘氨醇強效的抗菌及抗發炎的效果特別適合應用於治療粉刺問題肌膚,此外本產品植物鞘氨醇具有類固醇與抗生素的功效,卻沒有類固醇及抗生素的副作用,因此韓國多應用在幼兒用異位性皮膚炎產品中,能有效治療皮膚的搔癢和炎症。另外,因為植物鞘氨醇可以恢復皮膚的基本結構及其抗菌性強,所以可促進治療皮膚、傷口癒合的過程,亦適合敏感脆弱的肌膚。

實驗研究:消炎功效:植物鞘氨醇藉由抑製(蛋白激酶C)PKC酵素活性來達到消炎作用。另外,實驗研究顯示0.2%的植物鞘氨醇可有效控製發炎指標interleukin-1α,效果可媲美藥用類固醇(dexamethasone)。治療粉刺:實驗證實植物鞘氨醇對多種微生物都有極強的抑製作用。0.1%的植物鞘氨醇就可有效的抑製痤瘡桿菌,解決粉刺部位肌膚的問題!

【Phytosphingosine】

Rating: BEST
Benefits: Anti-Aging, Hydration
Categories: Emollient

Phytosphigosine is a long-chain, complex fatty alcohol that is found naturally in skin’s upper layers. It’s an essential part of maintaining skin’s natural moisturizing factor (NMF) for overall skin health. It’s also a base component of certain ceramides, which serve as part of skin’s structure.

Phytosphigosine in topical skin care products helps replenish skin’s barrier for a more youthful look and feel. Recent studies also show that phytospingosine can have a calming effect on skin, helping reduce redness and sensitivity.

Since this ingredient occurs naturally in skin and is essential for its healthy appearance, it is considered safe as used in cosmetics, where concentrations rarely exceed 1%. Indeed, amounts as low as 0.05% are considered effective.

One interesting note of trivia: the name phytosphingosine is derived from the term sphingoid, which was coined in 1884 by chemist J. L. W. Thudichum. The way the molecules of this substance lined up reminded him of the riddle of the mythological Sphinx.
