Step 1: File

Before using the nail buffer, we recommend using a nail file to shape the tips of your nails. It gives you a more complete look. Best practice for nail file: Start at the outer edge of one nail. Hold the file at a 45-90 degree angle against the nail edge and sweep the file towards the center of the nail. Avoid rubbing the file back and forth to prevent the nail from splitting. Repeat this movement as needed

Step 2: Buff

Use the buffer with clean, dry hands. Hold the block by its sides between your thumb and finger. (Avoid touching the white pads if possible. The oils in your skin can stain them and lessen the life of the pads.) Use slight pressure to slide the surface of the pad along your nail for about 5-10 seconds. Finish each step on all your nails before moving to the next step.

Step 3: Condition

Use the Cuticle Conditioner Serum for 2 consecutive weeks daily then 3 times a week. Dispense a small amount onto the nail bed of each finger. Then massage the serum into each of your nail beds, while you gently push the skin back down with your thumb. & How  


  • You will not need to use the block as often on your toenails. They naturally grow slower and are also less exposed to harmful substances.
  • Keeping your buffer in its wrapper, or in a protective bag will keep it clean and extend the life of the pads.
  • Convenient, Small, compact size is easily carried in a bag or stored in a drawer
  • Mess-free
  • Replaceable Pads for extended life
  • No harsh chemicals

Happy with this!

These photos are about 10 months apart. I have been biting my nails for years, and the picture on the left was taken Feb 2022 after I stopped biting them cold turkey. I found out I was going to be on TV and my hands would be in close-up shots, and the possible embarrassment of bitten fingernails overrode the compulsion to chew them! I’m also allergic to a lot of glues and nail products, so I couldn’t just go get a set of acrylics, and I have eczema on my hands that sometimes flares and can flake.I decided I wanted to find something to help my nails grow as well as make them shiny without having to paint them. I have used the buffer and cuticle cream maybe once a week, sometimes less frequently, but after finding the pic on the left while looking for something else in my camera roll I wanted to have a comparison picture from now, December 2022. I will definitely purchase more of this!
