Smudge-proof eyeliner

I bought the Liquid Define Liner from the brand Pro8 Cheongdam because I heard it is a product frequently used by makeup artists in salons. I purchased the brown shade, and I liked that it is deep enough to be a dark brown. Once set, it stays put for a long time without smudging, even on oily skin. It is resistant to sweat and water, so I can really see why most makeup artists use it. If you are worried about smudging, give this product a try!
