白柳樹的葉子是花的，白中帶綠，早春時還帶淡粉色，所以又叫Dappled Willow。到了秋天，葉子轉黃色，隨即掉落。冬天時，枝莖會轉紅色，所以說，一年四季都有顏色，難怪受歡迎。
Dermaveil 為白柳 (Salix alba L.) 之外皮萃取。 外皮中主要的成分已知為酚苷(salicin, salicortin, acetyl salicin, picein,等)、兒茶素及類黃酮。
楊素, 為一種柳樹及山楊中 大量含有的酚苷。它是阿司匹林的原料，為藥史上最重要的發現。
Salicin 是 Dermaveil 中的活性物質之一，在人體中被認為先轉換為 saligenin (salicyl alcohol) 然後變成水楊酸，水楊酸一般用來作為脫落劑。若 salicin 逐漸轉變為水楊酸，其能表現出溫和脫落活性。在乾燥或粗糙肌膚，老舊角質細胞聚積，使皮膚透明 感降低並使膚質變差。在這樣的皮膚，細胞不是正常的成熟。移去老舊角質細胞能夠促進 皮膚透明度且同時活化表皮角質細胞
白柳樹皮-White willow bark
The leaves of the white willow are greenish-white with flowers. In early spring, it was also light pink. So it is called Dapple Willow.In autumn, the leaves turn yellow and fall randomly. The stem turns red in winter. It has colors all year round, so it is very popular.
Dermaveil is extracted from the rind of Salix alba L. The main component of the outer skin of the tree are phenolglycoside(salicin, salicortin, acetyl salicin, picein…etc), catechins, flavonoids.
Yang Su,one of the willow and poplar contains much phenolglycoside, It is the raw materal of aspirin. It is the most important discovery in the history of medicine.
Salicin is one of the active substances of Dermaveil. In the human body it is considerred to be converted into saligenin (salicyl alcohol)
and become to salicylic acid. can show mildness and shedding activity.The aged keratinocytes gather on dry and rough skin.Remove of old karatinocytes can promote skin transparency and activate epidermal keratinocytes.
