Customer Reviews
Still my favorite lash serum!
Anyone else been using fLASH for years? I swear by their lash serum, my lashes are so much fuller and longer. I've tried other brands like Latisse but this one works just as well without irritating my sensitive eyes. Always grabbing their deals through email, it's usually like 20% off which makes a difference.
Serum delivered quickly
I ordered the fLASH Amplifying Eyelash Serum. Shipping was free and it arrived in about 6 days to my place in Ohio. The product itself was well-packaged. I've been using it for a couple weeks now and haven't had any irritation, which is good because my eyes can be sensitive. It applies easily with the brush. So far, so good on the lash front.
Decent product, slow support
I bought the Lash and Brow Duo. The serums seem good quality; I've used them for a while now and started seeing results with my lashes. The packaging was fine, and the free shipping was a plus. However, I had a question about application and it took customer service almost 48 hours to get back to me, which felt a bit slow. Overall, a solid experience but communication could be faster.
My lashes look amazing
Oh my goodness, I am so happy with my fLASH Amplifying Eyelash Serum! My lashes look so much longer and fuller after just a few weeks. I seriously can't believe the difference. I'm telling all my friends about this. I will absolutely buy from Flashcosmetics again!
Easy to order
Got the Sensitive Eyes Lash Serum. The website was easy to use and it shipped out pretty fast. No problems with delivery, it just showed up when they said it would. Happy with it.
Good value serum
I was looking for a lash serum that wouldn't break the bank. I got the fLASH Amplifying Eyelash Serum during a bundle deal, which saved me a decent amount. Felt like a smart purchase for the quality.

How long does shipping usually take to New York? Trying to decide if I should order it before a trip.
Hey, thinking of trying the eyelash serum. Anyone know if it actually works for sensitive eyes? I've had issues with other brands.
