Used before special occasions
Many reviewers explicitly save this mask for dates, events, photoshoots or important days because of its immediate depuffing/lifting look, rather than using it as a daily staple.
Low weekly frequency due to price
Multiple reviewers use it only once a week or once every other week, citing cost as the reason for limited frequency despite loving the results.
Applied after cleanser/toner as a treatment step
Reviewers describe applying it after their toner as a booster/treatment step, leaving it on roughly 20-60 minutes until mostly absorbed.
Two-part application (upper face + ear-loop lower band)
The mask is applied in two separate pieces—one for the upper face/eyes and one that hoops around the ears for the jaw/neck—often paired with the included fabric lifting band for extra snugness.
Layered with other numbuzin No.9 products or devices
Some consumers combine it with the No.9 serum/toner line or with at-home lifting devices (e.g., Medicube) as part of a fuller anti-aging routine.
