Core mechanism:
The laser hair removal device uses a single-wavelength focused beam (commonly 755nm/808nm/1064nm) to selectively act on melanin in the hair follicle, destroying the hair papilla through photothermal effects and inhibiting hair regrowth.
l Precision: The more concentrated the wavelength, the stronger the targeting of the hair follicle, avoiding damage to the surrounding skin.
l Depth: Different wavelengths have different penetration depths.
Differences from IPL:
Features | Laser hair removal device | IPL hair removal device |
Light source | Single wavelength, high focus | Wide-spectrum light, with a wide range of wavelengths |
Effect | Longer-lasting, suitable for coarse and hard hair | Use more frequently, effective for fine and soft hair |
The sensation of pain | Stronger (requires ice point technique for relief) | Milder |
Modern high-end laser hair removal devices achieve personalized hair removal through the following technologies:
l Optical sensor: Automatically detect skin color (Fitzpatrick grading), adjust energy to avoid burning dark skin.
l Hair color sensing: Recognizes melanin concentration and automatically disables low-efficiency wavelengths for light hair (gold, red).
l Multiple levels of energy (e.g. 5-20 j /cm²) : Adapt to different parts (low for the face, high for the bikini area).
l Multi-wavelength switching:
¢ 755nm (Alexander Laser) : Best for fair skin + dark hair.
¢ 808nm (diode laser) : Balanced effect and safety, versatile.
¢ 1064nm (Nd:YAG laser) : Designed for darker skin tones, it penetrates deep but requires higher energy.
l Contact cooling heads (0-10 ° C) lower epidermal temperature, reduce pain and redness, and enhance comfort.
l Small area mode (lip, armpit) : High-precision single flash.
l Large area mode (legs, back) : Continuous fast flashes save time.
l Best effect: Dark, coarse hair (black/brown) + light to medium skin tone (Fitzpatrick I-IV).
l Caution:
¢ For darker skin tones (V-VI type), a 1064nm wavelength instrument is required; otherwise, it is prone to pigmentation.
¢ People with white/gold/red hair, pregnant women, scar-prone skin, or photosensitive conditions.
l Initial stage: once every 4-6 weeks for 3-6 times (hair growth cycle affects effect).
l Maintenance phase: 1-2 consolidation sessions per year.
l Expected results: More than 90% hair reduction, with the remaining hair becoming thinner and softer.
