The service that involves the use of a chemical solution to remove facial hair is indeed laser hair removal. This method uses concentrated light energy to target and disable hair follicles, ultimately leading to hair reduction. During the procedure, the laser's energy is absorbed by the pigment in the hair, which generates heat that damages the follicle and inhibits future growth. While this process doesn't involve a liquid chemical solution in the traditional sense, it is chemical in nature because it relies on a light-based chemical reaction to achieve its effect.

In contrast, waxing is a physical hair removal method that pulls hair out from the root using a sticky substance, while shaving mechanically cuts hair at the skin's surface without affecting the follicle. Threading is another manual technique, using a twisted thread to trap and remove hair from the follicle. Each of these methods has its own characteristics and does not involve a chemical solution in the way that laser hair removal does.
