Been using consistently for two months. I no longer have little gaps between my lashes and they are so much fuller! The retention has been amazing, with minimal lash fallout. I will wait for them to get a little longer before I do a Korean Lash Lift. Love this product!!
I never write reviews but I had to do it with this one! I’ve been struggling with my lashes for so long! I barely had any and they were getting lighter I don’t know why. You can see it in my before picture. This lash serum changed my life! I never had lashes this full and thick! I’ve been using it for 4 months. Thank you Flash Lash!
Sin rímel, la verdad si me crecieron bastante pero mi genética no es de cabello abundante, me crecieron pero no hay más volumen pero me gustaron los resultados
Love this product!! It makes my eyelashes look longer and thicker so I don't have to use as much makeup on my eyes. It really makes them grow too, people think I have fake eyelashes
It exceeded my expectations! Super effective!
My eyelashes were too short and in 4 weeks boom 💥 I love them! 😍
I am 100% satisfied with the product!
Super recommended!⭐️⭐️⭐️⭐️⭐️
Ame! Probé otras marcas de serum, pero Flash hizo un gran cambio en la longitud, y eso que antes no tenía casi nada, es mi 2do tubo y volveré a adquirirlo!
I used this lash serum 2 months and my lashes grew so fast an longe, i love it and want to use it for a long time. In the fotos you can see how my lashes look today and for 2 months ago
Best serum I’ve ever used, the only serum that will work on my lashes. They’re thicker.. longer and there’s more lashes than ever. Also it doesn’t hurt to use everyday which is a bonus. They’re so long and beautiful! Thank you !!
I’ve always worn strip lashes or lash extensions because I had the shortest eyelashes that you couldn’t even tell I had any. This product is truly a game changer. I couldn’t be happier with my lashes! I am in love with them !!! This product truly works, just be patient and consistent and you will see results. I never imagined I would stop wearing strip lashes or getting extensions. I love this product so much!
So great I recommend it to all my friends. I’ve tried many eyelash growing solutions including the ordinary Serum and castor oil. But nothing grew it as well as this serum! I also posted a video in which the results are visible on my tiktok which now has over 4.6 million views! Everyone that comes across Flash eyelash serum loves it!
