My nails have always been weak and prone to breakage, but after using this kit, they look healthier and stronger than ever before. The nail buffer is fantastic; it leaves my nails looking smooth and shiny. The cuticle serum is also amazing, and it has helped me get rid of hangnails and dry cuticles. The best part is that this kit is natural and safe; I don't have to worry about harsh chemicals damaging my nails.

How to use

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 cuticle

Saved my hands and nails

Do you have splitting peeling nails and haggard cuticles? Well this kit is the cure. I had used Onsen Secret cuticle cream before and was very pleased with the how creamy and effective the product was. So I decided to give this kit a shot.I love wearing nail polish. But the polish would only last one to two days because of the condition of my nails. It would peel and chip immediately. So I saw this kit and thought I would give it a try. It only takes a small amount of time to make a big impact.One day a week you use the entire kit, using the nail file (with two different grits) to shape the nail. Then you use the 3 stage buffing block to brighten, smooth and shine your nails. After that you use the nail oil or cuticle cream to give dry cuticles a nice coat of moisturizer. And finish of the routine with the anti aging hand cream.You only have to do this 1x a week. Daily maintenance is alternating between the nail oil and cuticle cream 1-2x daily. Your nails will look amazing!And if you are a nail polish lover like me, it creates a beautiful and strong substrate for your polish. My nails are beautiful with or without polish. Just from this simple little kit. I highly recommend.
