Nail trimming

Cut the edge

The visible plaque is made up of keratinized cells. It is produced by the matrix located at the base of the nail, then advances above the nail bed. The cut acts at the other end, on the free part.

In a small study of healthy young adults, average growth was about 3.5 millimeters per month in the hands and 1.6 in the feet. Above all, they explain why a brand often has to advance for weeks or months before it can be completely cut.

A regular edge is less snagging

A sharp corner or small crack can catch on fabric and cause a tear further into the plate. Shortening reasonably and smoothing the edge reduces these snagging opportunities.

On the feet, the edge of the nail is in contact with the skin and is also subject to pressure from shoes. Digging the sides or cutting excessively short can encourage an ingrown toenail. A straight cut helps maintain an accessible edge, but an already painful nail is not treated simply by repeating this action with more force.

The cuticle is a protection

The cuticle forms a junction between the plate and the fold of skin located at its base. It helps protect the space beneath this fold from external aggression. Repeatedly tearing it out, cutting it or pushing it back can alter this protection and promote inflammation around the nail, called paronychia.

The plaque itself does not have the sensitivity of skin, but the tissue around and beneath it is alive. This is why a cut of the free edge is normally painless, whereas a cut too short, deep cleaning or a little skin torn off can hurt and bleed.

The limits of cosmetic maintenance

A new or evolving dark band, separation, marked thickening, or persistent pain should be evaluated. Cutting and polishing cannot establish the cause.

Biting your nails or constantly manipulating their edges can also cause lesions. Letting the tissues recover, reducing repetitive movements and protecting the skin is more important than seeking a perfect shape immediately. If the habit is difficult to control, professional help can complement practical daily adjustments.
