I never leave reviews but had to for this! I used Grande Lash in 2020 and loved the length, but had side effects like redness and under-eye fat loss. Other serums didn’t work until Lash By Diyana. I had low hopes, but my lashes are now so long and thick with no negative effects. I’m genuinely so happy I found this and inform everyone I know about this. Thank you so much – I’ll be buying forever, please never stop making it <3
