Fotona Laser Hair Removal
The Fotona laser system is renowned for its versatility and effectiveness in various dermatological treatments, including hair removal. It utilizes a range of laser technologies to provide precise and effective hair reduction.
The Nd:YAG laser operates at a wavelength of 1064 nm, which is in the near-infrared spectrum. This wavelength is selectively absorbed by melanin, the pigment found in the hair shaft and hair follicle. The 1064 nm wavelength penetrates deeper into the skin. It can reach the deeper layers of the dermis where hair follicles are located, making it effective for targeting hair follicles even in individuals with darker skin.
Selective Photothermolysis
The laser energy is selectively absorbed by the melanin in the hair shaft and the hair follicle. This absorption converts the laser light into heat, raising the temperature of the hair follicle to a critical level. Selective photothermolysis means that the laser is specifically absorbed by the melanin in the hair follicle while sparing the surrounding tissues, thus minimizing damage to the skin.
Long-Pulsed Duration for Effective Targeting
The long-pulsed Nd:YAG laser emits laser energy in pulses with durations that can range from milliseconds (ms) to several hundred milliseconds. The longer pulse duration allows the laser energy to be delivered slowly and steadily. This extended delivery time ensures that the heat is concentrated in the hair shaft and follicle long enough to cause thermal damage to the follicle while protecting the surrounding skin from overheating. This is especially important for treating thicker and deeper hair, as longer pulses allow the laser to penetrate more deeply and sustain the heat required to destroy the hair follicle.
Thermal Damage to Hair Follicles
The absorbed heat damages the hair follicle’s structure, specifically targeting the bulb and bulge areas of the follicle, which are crucial for hair growth. The heat effectively coagulates the proteins within the follicle cells and disrupts the blood supply to the hair follicle, leading to follicular necrosis (destruction of the hair follicle).
The Long Pulsed Nd:YAG laser is particularly effective for hair removal. It penetrates deeply into the skin to target the melanin in hair follicles, providing effective hair reduction while minimizing damage to the surrounding skin. It is suitable for all skin types, including darker skin tones. By using the Long Pulsed Nd:YAG laser in the Fotona 4D system, effective and safe hair removal can be achieved with a focus on comfort and long-term results.

Safe for All Skin Types:
The long pulsed Nd:YAG laser is suitable for a wide range of skin types and hair colors.
How does it work?
Targeting Hair Follicles
The laser emits a wavelength of 1064 nm, which penetrates the skin and is absorbed by the melanin in hair follicles. The energy from the laser heats up the melanin and the surrounding follicle, leading to the destruction of the follicle’s ability to grow hair.
Thermal Damage
The long pulse duration allows for sufficient thermal damage to the hair follicle without causing excessive damage to the surrounding skin. This thermal effect disables the follicle, leading to permanent hair reduction.
Safety Across Skin Types
The Nd:YAG laser is effective on all skin types, including darker skin tones, due to its longer wavelength, which reduces the risk of pigmentation changes and burns.
Cooling Systems
Advanced cooling systems, often integrated into the Fotona laser, help to protect the skin and enhance comfort during the treatment by cooling the surface of the skin while the laser targets deeper layers.
People who seek for permanent hair reduction can opt for Fotona Laser Hair Removal treatment.
Session Duration
Each treatment session typically lasts between 15 to 60 minutes, depending on the area being treated.
Treatment Frequency
Hair removal usually requires multiple sessions, often spaced 4 to 6 weeks apart, to effectively target hair in different growth cycles.
Number of Sessions
Most patients require 4 to 8 sessions for optimal results, but this can vary based on individual factors such as hair density, color, and the treatment area.
