Avoid filing too deeply into the corners of the nails to prevent what?

Filing too deeply into the corners of the nails can lead to ingrown nails. Ingrown nails occur when the edges of the nail begin to grow into the surrounding skin, which can cause pain, inflammation, and even infection. This situation is often exacerbated by improper nail care techniques, such as aggressive filing.

Maintaining the proper shape and smoothness of the nail without digging too deep into the corners helps to ensure that the nail grows outward rather than curving into the skin. This practice is essential for preventing discomfort and promoting healthy nail growth. While brittle, chipped, and weak nails can also stem from improper nail care, the specific concern regarding filing too deeply is primarily related to the risk of developing ingrown nails.
