Hi everyone, just a quick question - has anyone had any luck with reasonably-priced lash growth serums?

I used to use the Rodan + Fields one; it worked but it's just too pricey for me to bother with. I'm loving my minimal makeup routine lately, and slightly thicker and longer lashes would perk it up! (and be great when pool season arrives and mascara's not as good an option).

Thanks if you have recos. xx H.
