Lancer lash serum vs Rodan and Fields lash boost?

[Jocelynkb]

I have been using the RF for about 2 years. Not all the time but i go thru phases with it. I love it and it really makes my lashes grow so long. So long they touch my sun glasses and i can feel them moving in the wind. Ha. But has anyone tried the Lancer version? I hear it makes them longer and thicker which the RF does not do. But that it can cause mild irritation. Has anyone tried both and have an opinion and or preference? TIA
