The Dermathod Clearance C4 Mask is a professional two step carboxy therapy system designed to enhance skin oxygenation, improve microcirculation, and support visible skin clarity. The treatment works by generating carbon dioxide on the skin surface, triggering the Bohr effect and increasing oxygen delivery to the tissues. This physiological response helps brighten dull skin, support detoxification, and improve overall tone and texture.

The system is structured in two separate steps to ensure stability and consistent activation.

Step one is an CO₂ activating gel applied directly to the skin, designed to initiate controlled carbon dioxide release on the skin surface. Step two is an activating sheet mask that seals the gel, sustains the CO₂ reaction, and supports skin balance and comfort following the oxygenation process.

The Clearance C4 Mask is formulated with functional brightening and skin conditioning ingredients, including Tranexamic Acid, Citric Acid, and a Citrus Complex, which work synergistically to support even skin tone, enhance clarity, and reinforce the effects of increased circulation. Hydrating and soothing components help maintain skin comfort throughout the carboxy process and minimise post treatment sensitivity.

Each box contains five complete treatments, making the C4 Mask suitable for professional clinics, structured treatment courses, and controlled skin programmes.
