It feels like a mixture of oils and oils are good for the lashes. It does not get into my eyes as it is not so runny and it does not sting my eyes as it has no smell. Really like this and have replaced my regular day mascara with this.
I think this eye serum is okay. I have not been consistent enough with it to see results except that I have less eyelash fall off. I like that it does not burn my eyes when I use it. It takes a while to dry on my eyelashes so I can only use it at night.
