How do the single-use sachets work — can I save an opened one for later?

The product comes as two 7 ml sachets. Each sachet contains enough mask for one full-face application (and neck if desired). Tear along the perforation, squeeze the contents onto clean fingertips or a small bowl, and apply immediately. The sachet format eliminates the need to dip fingers into a jar, which reduces contamination risk and keeps the texture consistent from first use to second.

Once opened, the sachet cannot be reliably resealed. Kaolin clay begins to dry on air exposure, and the preservative system is calibrated for single-use portions, not for an opened package stored over days. If you only want to treat the T-zone, you can still open a full sachet, use what you need, and discard the remainder — or apply the excess to the neck, chest, or back of hands for the same purifying effect.

Store unopened sachets at room temperature, away from direct sunlight and heat. The cardboard outer packaging protects them from light and mechanical damage. There is no need to refrigerate; cold temperatures can alter the emulsion texture. Check the expiry date printed on the sachet or outer box before use.
