What is the hair removal technique that uses laser light to destroy hair bulbs and follicles?

The technique that uses laser light to destroy hair bulbs and follicles is known as photothermolysis. This method relies on the principle of selective photothermolysis, where specific wavelengths of light are absorbed by the melanin in the hair follicles. The energy from the laser is then converted into heat, which damages the hair follicles enough to inhibit future hair growth. This makes photothermolysis an effective and widely used method for laser hair removal.

Other techniques, while related to hair removal, utilize different mechanisms. For instance, electrolysis involves using an electric current to destroy hair follicles individually, rather than employing laser light. Thermolysis, also known as shortwave diathermy, uses radiofrequency energy to produce heat for hair removal and is typically less common than electrolysis and laser methods. Laser ablation, on the other hand, generally refers to the process of removing or vaporizing tissue using laser energy and is not specific to hair removal techniques.

Thus, photothermolysis is distinct in its use of laser technology specifically designed to target hair follicles, making it the correct choice for this question on laser hair removal methods.
