Applying: It is extremely light. It feels like I'm washing my eyes with water and there's hardly any irritation. Even if a little product get in my eyes, it feels like nothing. There's absolutely no oily substance left over leaving no residue.
Effectiveness: It gets off almost all my eye makeup off with ease. Dab some on a cotton ball, gently rub it over your eyelids, clean up the excess with q-tips, and you're done.
Final Thoughts: I highly recommend this product to anyone with sensitive eyes. Although it is priced at $18, this is a splurge I will be willing to spend. It is highly effective and non-greasy making every penny worth it.
