What technique is used to remove unwanted hair accompanied by a topical anesthetic?

Laser hair removal is a technique that effectively addresses unwanted hair by utilizing concentrated light to target hair follicles. The application of a topical anesthetic is common in this method to enhance patient comfort during the procedure, as the laser can produce sensations similar to a snapping rubber band on the skin. The topical anesthetic numbs the area to minimize discomfort, making the overall experience more tolerable for the individual undergoing the treatment.

In contrast, waxing is a method that removes hair from the root using a sticky substance but does not typically incorporate a topical anesthetic, as the procedure involves pulling hair out against the direction of growth, which can be painful. Epilating also removes hair from the root but is primarily associated with using an epilator device, and like waxing, it generally does not involve the use of a topical anesthetic. Shaving simply trims the hair at the skin's surface and does not require any anesthetic since it does not cause the same level of discomfort as the other techniques mentioned.
