laser hair removal can removal the most hairs even your olive skin tone.
but your age is a problem, All laser hair removal clinics require a parent or legal guardian’s consent to perform the procedure on a child under 18 years of age.

Teens should also understand that several visits might be required to remove all the unwanted hair. Four visits are the average, but it might take less depending on the amount of hair that needs to be removed, and the color of the patient’s hair and skin.

Another thing to consider for teens is whether or not they tan their body frequently, either in the sunlight or a tanning facility. A tanned body does not react to laser hair removal positively in many cases. The reason? Tanned skin can prevent some of the laser energy from reaching the hair follicles because the darker the skin, the more light energy it absorbs. When the skin absorbs much of the light, the hair follicles are deprived of the light, and the skin might also be burned during the procedure, causing discomfort. Before the procedure, teens should avoid tanning for as long as possible by wearing strong sunscreen while outdoors.
