The mask is quite thin. Good fit and adhesion. The slit is approximately 3 cm long and can be torn out. The essence has a transparent colour and a jelly-like feel. It has a pleasant smell, yet it is not overpowering.
When the mask was removed after 15 minutes, it was practically dry. However, there is still a lot of essence on my face that hasn't been absorbed yet. I continue massaging until all of the essence has gone.
My skin is plump and soft. My pores appear to be more refined. There was no brightening observed. I awoke with soft skin. Even though I used the K94 mask in an air-conditioned room, my skin remained hydrated after 24 hours. I also noticed my skin appears to be brighter (after 24 hours).
