For sensitive, thin, or reactive skin, once every 7–10 days is a safe starting frequency. Skin that tolerates the mask well without tightness or irritation can gradually increase to twice weekly, but daily use is not recommended — even gentle clay removes surface lipids that need time to replenish. Apply on clean, slightly damp skin after your regular cleanser; this helps the paste spread evenly and reduces friction.
Immediately after rinsing, while skin is still damp, apply a hydrating toner or essence, then a serum if you use one, and finish with a moisturizer. Avoid leave-on exfoliants (AHA/BHA), retinoids, or vitamin C on the same evening — the skin's barrier is temporarily more permeable post-mask. On non-mask days, keep the routine simple and barrier-focused. If you use the clay on the body (décolleté, back, shoulders), the same frequency guidelines apply; body skin is generally thicker but can still become dry with overuse.
Store the powder in its original pouch or an airtight container, away from humidity and direct sunlight. The 100 g pack has no water content, so shelf life is long (typically 24–36 months from production) if kept dry. Discard if you notice clumping that doesn't break up, an off smell, or discoloration beyond the natural red hue.
