I want laser treatment for underarms hair, but am afraid that it will harm my sweat glands. Can sweat glands be destroyed after laser hair removal?

If you are worried about harm to your sweat glands during laser hair reduction, you should know how laser hair removal works first.Laser hair removal targets the melanin pigment in the hair follicle, which absorbs the laser energy, heats up, and is destroyed. This also destroys the stem cells in the follicle leading to restriction in hair growth. Hair follicles are associated with sebaceous or oil glands in many parts of the body, which are occasionally affected by laser energy. However, sweat glands are not associated with hair follicles and are located deeper in the skin. Therefore, laser energy doesnot reach them and has minimal effect on them.It is sometimes possible to experience temporary changes in sweat production immediately after the procedure, as the skin may be temporarily irritated and inflamed. This may lead to increased sweating or decreased sweating in the treated area for a short period of time. However, these changes are usually temporary and resolve on their own within a few days to weeks.Thus, laser hair removal should not have any significant impact on the sweat glands in your underarms. Any changes in sweat production are usually temporary and resolve on their own. However, it is essential to consult an experienced and qualified dermatologist before undergoing the procedure, to understand and minimize the risk of potential side effects.
