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.
