Yes you can as it provides the same effect too!

Cavilla Lash Serum can be applied using "eyeliner" method. Just line the roots of your lashes with our serum will do.

There might be 2 reasons: 1) Serum might have gotten into your eyes when you blink. And there is EPM in the serum, hence it cause redness. Avoid applying it into your eyes. 2) Start controlling the amount of serum that you are applying, as the serum helps to promote blood circulation hence then thin skin around the eyes are sensitive towards it.
