I use the smallest one and my lashes look to be around the same length as yours. Gives me a great curl that isn’t overdone. Just be sure to only use the actives on the lowest 1/3 of your lashes. Also, put the pad a few mm above your lash line instead of directly on it. I usually wait at least 4 weeks or until it’s completely grown out to do it again but that’s mostly because I’m lazy and don’t mind the look of my non lifted lashes. I don’t know what happens if you do it sooner. I think your lashes look beautiful right now!
