Laser hair removal serves to progressively and permanently reduce hair growth by directly targeting the hair follicle.
⚙️ How it works
The principle is that of selective photothermolysis:
- The laser emits light with a specific wavelength.
- The light is absorbed by the melanin in the hair.
- The light energy is transformed into heat.
- The heat damages the hair bulb without damaging the surrounding skin.
- The result is a progressive reduction in regrowth, resulting in finer, sparser, or even completely absent hair.
🎯 What it actually does
✔ Destroys the follicle in its growth phase (anagen)
✔ Slows regrowth
✔ Reduces ingrown hairs and folliculitis
✔ Improves skin quality over time
📆 Why do multiple sessions need to be done?
Not all hairs are in the same growth phase.
The laser is only effective on hair in the anagen phase, so multiple sessions are needed to target all follicles at the right time.
🌿 Benefits over traditional methods
- Longer-lasting results compared to waxing or shaving
- Less irritation
- Smoother skin
- Long-term savings
🔹 Diode Laser
The diode laser is one of the most widely used technologies in beauty salons and medical-aesthetic practices for:
- Progressively permanent hair removal
- Skin photostimulation
- Treatments for light and dark skin (depending on the wavelength)
⚙️ How it works
- It emits a wavelength generally around 800–810 nm, selective for the melanin present in the hair bulb.
- The heat generated destroys the follicle in the growth phase (anagen), progressively reducing regrowth.
✅ Advantages
- Excellent balance between efficacy and safety
- Suitable for many skin types
- Relatively quick treatments
- Established and reliable technology
🌿 Diode laser and photostimulation
With specific parameters and lower power levels, it can also be used for:
- Collagen stimulation
- Improvement of skin texture
- Anti-aging treatments
🔹 Fiber Optic Laser (Fiber Laser)
The fiber optic laser is a more recent technological development. It uses a fiber source that allows for greater energy stability and beam precision.
It also often operates around 808 nm, but with more efficient energy transmission.
⚙️ How it works
The energy is generated and transported through an internal optical fiber, ensuring:
- A more stable beam
- Less dispersion
- More efficient cooling
✅ Advantages
- Longer handpiece life
- Reduced maintenance costs
- Greater client comfort
- High power with precise control
🌿 Fiber Photostimulation
Thanks to the precision of the beam, it can be used for:
- Tissue biostimulation
- Light vascular treatments
- Improved skin elasticity
