Why You’ll Love It
This face mask is made with a serum rich in bicarbonate ions, created by the neutral bicarbonate bath additive brand "BARTH." It features a separate formulation that requires mixing just before use. The BARTH powder dissolves in the serum in the bag, generating bicarbonate ions. The serum, containing fresh bicarbonate ions, tightens and refines skin texture. [Key Features] Firms and radiates with a serum rich in bicarbonate ions. The serum's neutral pH generates bicarbonate ions. The bicarbonate ions are fully dissolved in the serum, eliminating any crackling sensation. The serum, rich in bicarbonate ions and containing organic moisturizing ingredients (lavender flower extract, sage leaf extract, and rosehip fruit extract), penetrates deep into the stratum corneum, leaving skin firm and radiant. Free of nine synthetic fragrances, alcohol, glycerin, mineral oil, parabens, silicone, synthetic colorants, UV absorbers, and animal-derived ingredients. The face mask is made with 100% pure cotton sheets.
How to Work It Into Your Routine
It takes about 3 minutes for bicarbonate ions to be generated. It is recommended to prepare it before washing your face. Fold the bag in half and press firmly on the serum side to transfer the serum to the BARTH powder and face mask side. Once the serum has flowed into the face mask, gently shake the bag and leave it for about 3 minutes. Once the serum and powder have mixed, bicarbonate is generated and the bag has expanded slightly, gently massage it to thoroughly absorb the serum into the face mask. Place the face mask on your skin after washing your face. Leave it for 5-10 minutes, then remove the mask and gently massage any remaining serum into your skin with your palms. After use, proceed with your usual skincare routine.
