according to dr Dana Stern, a world-renowned nail expert and the only board-certified dermatologist in the United States to dedicate her entire practice to nail diagnosis, treatment, and surgery, many nail files and traditional emery boards can be too abrasive for natural nails and can cause microscopic cracks at the nail tip , leading to breakage, damage and premature chipping of the polish.
Emery Boards vs. Glass Files
The difference is illustrated in these enlarged images of two different nails – one using an emery board and the other using Dr. Dana’s newly introduced Precision Glass Nail File ($10).
The precision glass nail file from Dr. Stern features high-performance grit with precision technology to gently shape and contour natural nails for a smooth edge. Even weak or brittle nails can be filed in all directions without damaging the nail.
Other benefits according to Dr. Stern using her glass nail file:
- Longer Lasting Manicure: The glass file by Dr. Dana creates a smooth nail edge that minimizes snags and allows nail polish to adhere better, last longer and have less chipping. In fact, regular use of Precision Glass Nail File seals the nail’s keratin layer to make nails more resistant to chipping, chipping and breaking.
- Stronger natural nails: Regular use of Precision Glass Nail File seals the nail’s keratin layer to make nails more resistant to chipping, chipping and breaking.
Combine the nail file with the nail renewal system from Dr. Dana ($30), which can be used to treat a variety of nail health issues such as dry, brittle, weak, ridged, discolored, peeling, and/or damaged nails.
