What is the purpose of creating a hairline tip by removing some polish from the free edge?

The purpose of creating a hairline tip by removing some polish from the free edge primarily serves to help prevent polish from chipping. When a thin line of polish is left at the free edge, it reduces the chances of the polish catching on surfaces and promotes a longer-lasting manicure. Removing excess polish can also alleviate tension at the tips of the nails, where chipping is most likely to occur. This practice ensures that the polish adheres better and can withstand daily wear and tear, ultimately leading to a more durable finish. While other options discuss different benefits like appearance or speed, the main focus of this technique directly addresses the longevity of the polish.
