During a full back laser hair removal session, a handheld laser device is used to emit precise and controlled pulses of light. This light is absorbed by the melanin in the hair follicles, generating heat that damages the follicles and prevents or delays future hair growth.

The benefits of full back laser hair removal include long-lasting results, reduced hair density, and the potential elimination of ingrown hairs. The number of sessions required varies depending on individual factors such as hair color, skin tone, and the hair growth cycle.
