Do you use eyelash serum?

I bought this product because I heard it's good to apply eyelash serums consistently. Maybe it's because it's summer, but I've been skipping my basic skincare routine, so my skin feels weaker overall. I was also concerned about my hair, so I ended up buying an eyelash serum. I've tried several brands before but ended up throwing them away after using them a few times, so I'm determined to use this one for a longer period.
