CytoSkin 維C混合精華採用獨有Zymo-C配方，將維他命C以Substrate及Enzyme分開儲存，讓精華只在混合時才釋出新鮮左旋維他命C，避免維他命C因氧化而令功效減弱消失。左旋維他命C是唯一可以被人體吸收及利用的維他命C，具極高的滲透力。除了促進膠原蛋白製造外，其特強抗氧化效果可防止肌膚細胞老化及抵禦紫外線傷害，更能淡化黑色素及抑制其形成，帶來淡斑美白功效。配合熊果素溫和抑制酪氨酸酶，淡斑美白效果更佳。

CytoSkin Zymo-C Vital Complex features a unique Zymo-C formulation that separates Vitamin C into Substrate and Enzyme components, keeping them apart until mixing to prevent oxidation and maintain maximum efficacy. This innovative delivery system ensures the freshest L-Ascorbic Acid is released at the moment of use. L-Ascorbic Acid is the only form of Vitamin C that can be absorbed and utilized by the human body, with exceptional penetration power. It promotes collagen production, provides strong antioxidant protection against cellular aging and UV damage, and effectively lightens pigmentation while inhibiting melanin formation for brighter, more even skin tone.
