How often should I use this mask and what's the correct way to apply it?

Apply the mask to clean, dry skin 1–3 times per week. Spread an even layer over the face, avoiding the eye area and lips. Leave it on for 15–20 minutes — this contact time lets the snail secretion filtrate's glycosaminoglycans, allantoin, and glycoproteins work on the skin surface. Rinse thoroughly with lukewarm water and follow with your usual toner, serum, and moisturizer.

If your skin feels comfortable, you can use it up to three times weekly. If you notice any tightness or sensitivity, drop back to once a week. The mask is richer than a daily cream, so it doesn't replace your daytime or nighttime moisturizer — it supplements them on the days you use it. Morning or evening both work; some people prefer evening so the skin can recover overnight.

Store the tube at room temperature with the cap closed. The 177 ml size gives roughly 20–30 applications depending on how thickly you apply it. If the texture or smell changes noticeably, discard it.
