I AM IN LOVEEEE!! These biogel pads are probably the easiest to work with! I’ve worked with the hydrogel pads and those are horrible they don’t stick a lot of client have reactions to the hydrogel and they big and bulky! I just started using these after going to a lash salon and asking them what under eye gel pads they use lol they told me and the rest is history. There’s no need for tape for extra security for bottom lashes like it’s needed for the hydrogel. Once you stick these gel pads on they STAY and if you have to re apply them for client comfort they do NOT lose there tackiness I LOVE LOVE LOVE THEM !
