Almost too good?
I have short and straight eyelashes. This is the only booster that’s worked for me. A little too well, actually, because my lashes have been able to reach my glasses. To remedy this I tend to use it slightly less often.

This stuff WORKS!
This stuff works wonders! Unfortunately I didn’t think to take a before picture when I started using it, so you’ll have to take my word for it. But after using it consistently, I started noticing a visible difference in the length and volume of my lashes.I’ve continued using it regularly and have now reached a point where I don’t need to apply it every day anymore. My lashes have maintained their length and fullness, so using it a few times a week is enough to keep them looking long and strong.I’m still using the same tube from when I first started, and it seems like it will last quite a while—especially since I’m no longer applying it daily.I’ve received many compliments on my lashes recently, which really confirms the results. Before using this, I’d say my lashes were more on the medium to shorter side. Now, I’m convinced this product truly makes a difference.It also doesn’t irritate my eyes like some other lash serums I’ve tried.It’s not the most affordable option, but it does work. I’d definitely recommend it if you’re looking for noticeable improvements in length and volume with minimal irritation.
