Well, it gets me the cooling feeling as soon as I put the masks on my cheeks like I put some plaster.
It explained that I can feel the cooling after 5 minutes, but I get it as soon as i put it.
It could be a little sticky in the very middle of summer, but the essence is tooooo enough to put it for an hour.
It recommend to put some cream in the last step, but it is enough for me tho. (but it recommend it so i put some on my face lol) It feel moisture even the day after.
