優色林抗色素雙重精華有助於對抗黑色素，黑色素是一種賦予皮膚顏色的天然色素。陽光照射、荷爾蒙影響和老化都會導致黑色素生成增加並引發色素沉澱。
色素沉澱表現為黑斑和老年斑（也稱為曬斑），使皮膚看起來不均勻。優色林抗色素雙重精華液結合了兩種以不同方式發揮作用的精華液：
- Thiamidol：一種專利成分，可從根本解決色素沉澱問題
- 濃縮透明質酸：皮膚保濕物質之一，有助於皮膚吸引和保持水分。輕盈的乳液可減少黑斑並防止其再次出現，同時更新皮膚外觀。兩週後即可看到初步效果，並且隨著定期使用會不斷改善。
每天一次（早上或晚上）塗抹於清潔後的臉部、頸部和上胸部
按下分配器頂部的中間，以確保釋放相同量的兩種精華液。第一次使用產品時，您可能需要按壓三到四次才能看到精華液出現。
