The Science Behind the 808nm Wavelength
The 808nm wavelength is in the near-infrared spectrum and has an optimal absorption rate in melanin, the pigment found in hair follicles. It penetrates deeper into the dermis than other wavelengths, reaching the bulge, bulb, and papilla of the hair follicle while ensuring minimal impact on surrounding tissues.
Why 808nm is Ideal for Hair Removal:
- High Melanin Absorption: Effectively targets the melanin in the hair follicle while minimizing absorption in surrounding skin.
- Deep Penetration: Reaches the hair root more effectively than shorter wavelengths, ensuring permanent hair reduction.
- Reduced Skin Damage: Unlike IPL (Intense Pulsed Light) or shorter laser wavelengths, 808nm limits damage to surrounding tissues, making it safe for all skin types.
- Faster Treatment Time: The combination of high peak power and efficient cooling systems allows for quicker treatments with minimal discomfort.
How Laser Hair Removal Works
Laser hair removal using an 808nm diode laser follows a simple yet effective process:
1. Selective Photothermolysis
- The laser emits a controlled 808nm wavelength, which is absorbed by the melanin in the hair.
- This generates heat that destroys the follicle, preventing future hair growth while leaving surrounding skin unharmed.
2. Follicle Disruption
- The heat damages the follicle’s ability to produce hair by targeting the hair bulb and bulge (the two key areas responsible for regrowth).
- Over multiple sessions, hair growth is significantly reduced, with long-term results achieved.
3. Cooling Mechanism for Comfort
- Advanced diode laser devices, such as the TrioPro from AVANTA Medical, incorporate DualChill technology to enhance patient comfort and prevent burns.
- Cooling tips and sapphire contact cooling ensure pain-free treatments, even on sensitive skin.

Frequently Asked Questions (FAQ)
How many sessions are needed for optimal results?
Most patients require 6-8 sessions spaced 4-6 weeks apart to achieve permanent hair reduction. The number of sessions varies based on hair type, color, and treatment area.
Is 808nm diode laser hair removal painful?
No, thanks to advanced cooling technology, treatments are generally pain-free or cause minimal discomfort, similar to a warm sensation on the skin.
Does it work on all hair colors?
The 808nm wavelength is most effective on dark, coarse hair due to its higher melanin content. Lighter hair may require alternative laser treatments.
Is the 808nm diode laser safe for darker skin tones?
Yes! Unlike shorter wavelengths (like 755nm), 808nm penetrates deeper without excessive absorption in melanin, reducing the risk of hyperpigmentation or burns.
Can it be used on all body areas?
Yes! The 808nm diode laser is suitable for the face, arms, legs, bikini line, back, and underarms.
