How often can I use this mask, and where does it fit in my regular skincare routine?

The mask is designed for intermittent, targeted use — 1 to 2 times per week is sufficient for most people. Using it more often does not increase the temporary benefit and may lead to unnecessary product waste or irritation from repeated occlusion. Ideal timing: after cleansing and toning, before any serums or moisturisers. The essence left on the skin acts as a light hydrating layer; once massaged in, apply your usual serum (e.g., hyaluronic acid, niacinamide) followed by moisturiser and, in the morning, sunscreen. If you use retinol or strong acids (AHA/BHA) in your evening routine, schedule the mask on a non-active night to avoid compounding sensitivity. There is no need to "prep" the skin with extra steps — a clean, damp face is enough. Store unopened sachets at room temperature, away from direct sunlight; do not refrigerate, as cold can alter the emulsion texture. Once opened, use immediately — the mask cannot be resealed or saved for later.
