LASER HAIR REMOVAL
About
What is Diode Laser Hair Removal?
Diode laser hair removal is a popular, non-invasive procedure for reducing unwanted body hair, utilizing a specific wavelength of light to target melanin in the hair follicles. The technology behind diode lasers involves a semiconductor as the active medium, which is efficient for the absorption of melanin, making it particularly effective for hair removal treatments. Laser technicians use diode laser hair removal systems, which emit wavelengths typically ranging between 800 nm to 810 nm — optimal for deep penetration and absorption by the pigment in the hair follicles. This method of hair reduction is widely acknowledged for its efficacy across various skin and hair types.
Provides treatment for a wide range of skin types using adaptable wavelengths
Targets hair pigment with high precision due to direct light emission
Facilitates long-lasting hair reduction outcomes with multiple sessions
Offers a relatively quick process compared to other hair removal techniques
Diode laser technology remains increasingly popular among both patients and clinics due to its balance of effectiveness and safety. Reported success rates in hair reduction after a full treatment course using diode lasers can be as high as 95%.
The benefits of using a diode laser over other types of lasers also include the capability to treat larger body areas rapidly, thanks to larger spot sizes, while maintaining comfort with cooling mechanisms. While at-home diode laser hair removal systems are available, and gaining in popularity, professional treatments are still recommended for comprehensive and safe results.
How Does Diode Laser Target Hair Follicles?
Diode laser technology precisely targets hair follicles through a process designed to disrupt hair growth at the source without damaging surrounding skin. The laser emits a concentrated beam of light absorbed by the melanin in hair follicles, generating heat which damages the follicle and impacts its ability to regrow hair.
The fundamental steps in which a diode laser systematically targets hair follicles during hair removal include:
Emission of Near-Infrared Light: Diode lasers commonly operate at a wavelength of around 800 to 810 nm, which is conducive to deep penetration into the skin where hair follicles are located.
Selective Photothermolysis: The light energy is transformed into thermal energy as the melanin in the hair follicles absorbs the light, leading to heating of the follicle while sparing the surrounding tissue.
Impairment of Follicles: The generated heat damages key structures within the follicles – specifically the hair matrix and the stem cells in the bulge region of the follicle – to inhibit future hair growth.
Treatment Efficiency: Diode lasers are equipped with cooling systems to provide comfort during treatment, allowing higher fluence rates for effective hair reduction. Studies have shown efficacy rates can be as high as 90% hair reduction after several sessions.
