Filing the nails from the outside edge toward the center is the recommended technique to avoid nail damage. This method is gentle on the nail structure and minimizes the risk of splitting or tearing. By directing the file toward the center, you support the natural growth of the nail and maintain its strength. This approach also helps to avoid creating weak spots that can lead to breakage.

Using other filing techniques, such as filing back and forth or side to side, can create friction that weakens the nail plate and increases the likelihood of damage. Filing in a circular pattern can also lead to uneven edges and disrupt the nail's integrity. Therefore, the technique of filing from the outside edge toward the center is the safest and most effective way to maintain healthy nails.
