matte. The texture is smooth and creamy and glides on very easily. If you apply a heavy coat it takes some time to dry Bur if you have applied a thin coat it dries off quick and then its smudge proof. It is waterproof. I don’t know about 36H because I have never worn makeup for that long but as you can see I wore it for 10 hours and it didn’t budge at all. I really like this gel liner; it does what it says… I don’t have any complains about this product but it would have been nice if the brush was an angled brush.
Hope you found this review helpful, Have a nice day
