My lashes look so long!

I just got my fLASH Amplifying Eyelash Serum and it's already making a difference! I saw results in just under a month, my lashes look amazing. Shipping was super fast, arrived in 4 days. I'm telling all my friends about this, you have to try it!

Consistent results, good price

I've ordered the fLASH Amplifying Eyelash Serum a few times now. This last one was just as good as the others. Packaging is always secure, and it arrived in 6 days to Seattle. My lashes look fuller after a few weeks, which is why I keep coming back.

hey, was thinking about trying the fLASH serum, but I have pretty sensitive eyes. Anyone know if their serum is okay for that?

A Amber 4 months ago
Yeah, they actually have a specific one for sensitive eyes. I use it and haven't had any issues, and my eyes get irritated by everything.

I think their regular one is supposed to be pretty gentle too, but if you're really worried, just go for the 'Sensitive Eyes Lash Serum.' It's clearly labeled on their site.

Anyone know how long shipping usually takes for Flashcosmetics? I'm in New York and need it kinda fast.

P Phil Lindqvist 4 months ago
Shipping was pretty quick for me to California, like less than a week. Dunno about NY specifically though.

They ship worldwide, so NY shouldn't be an issue. You can usually find tracking info in your email after you order to see the exact ETA.
