Filing from the outer edge towards the center is the recommended technique for filing natural nails because it helps to prevent splitting and damage to the nail. This method maintains the integrity of the nail by minimizing stress at the edges, which can lead to breakage if filed incorrectly. By starting at the outer edge and working inward, the nail technician can create a smoother, more polished look without compromising the overall structure of the nail. This technique also allows for better control of the filing process, helping to achieve a uniform shape and reduce the risk of over-filing.

Other filing techniques, such as filing from the center towards the outer edge or using a circular motion, can increase the chances of damaging the nail by creating stress on the tips or by introducing unevenness. Filing in a straight line from tip to base may not provide the necessary shaping and can lead to sharp edges that could snag or break. Therefore, the outer-edge-to-center technique is favored for its effectiveness in promoting nail health and achieving an aesthetically pleasing appearance.
