Our Solar Fill In will take 7 steps: Step 1: Remove old nail polish. Step 2: Trim your nails by using nail scissors or nail clippers. Step 3: Buff the surface of your nails, use a soft nail file to make the surface of your nails slightly rougher and less shiny. Step 4: Use a cuticle pusher to push back your cuticles.
