To me-


Kohl eyeliners tend to be more dark in pigment, softer in texture and tend to be more matte in shade. I also find that Kohl eyeliners are best for achieving a dark smoky smudgy look or to use in the inner rims of the eyes- it doesn't tend to irritate and seems to 'stick' on better.





Regular eyeliner can be several different things. But to compare the two a plain regular eyeliner pencil tend to have more wax, not a dense and doesn't smudge as easy as Kohl and come in a wider range of colors.What is the difference between eyeliner and kohl pencils?
Kohl pencils are softer and roll on smoothly. They are easier to smudge and are used mostly for a bold smokey effect. Where as regular eyeliner can less intense, and are used for natural looks.
