Hi everyone I am having a heck of a time forming my smile line I feel like a student as I am a cosmo but I know want to focus on nails but don't have much practice...... anyway does the brush we use help that much or is it just the hand that's using it? I feel I did waste my money when I bought my bursh it is from No lift Nails. I am pritty sure it is not firm enough for me to move the white around. Which brush do you use? Thanks alot
