The 1064 nm Nd:YAG FRAC3 ® method is optimized to deliver high intensity laser pulses in extremely short times of less than 2 ms, sufficiently short to destroy most hair types while avoiding unnecessary damage to the epidermis. Due to the relativelly low absorbtion in melanin, Nd:YAG laser treatments can be used safely and effectively even with darker skin types.
The Nd:YAG laser source has the depth of pene- tration necessary to reach and destroy even the deepest hair follicles and can successfully be used on all body areas.
Fotona’s Nd:YAG laser energy is absorbed selectively by the hair bulb and hair matrix, thus destroying the hair follicle. The FRAC3 ® pulse produces a three-dimensional fractional pattern within the epidermis and dermis, with energy being absorbed predominantly at the sites of small skin imperfections before heat is transferred to the surrounding non-target structures.
Laser parameters can be adjusted quickly and easily according to your patient's skin type, hair thickness, hair color as well as depth of hair follicles. Nd:YAG FRAC3 ® pulses should be administered with a slight overlap covering the entire treatment surface. Apply cooling to maximize comfort during the treatment.
Special post-treatment care is not required. Follicles treated in the anagen phase should fall out in approximately 2-3 weeks. Observe if new growth is present and repeat the treatment if needed. The treatment schedule will depend on each individual’s hair growth cycle.
One of the challenges when performing laser hair removal is the relatively low absorption of laser light in the treated hair, especially when the hair is blond and/or the skin is dark. Using the Avalanche FRAC3 ® procedure, low energy FRAC3 ® laser pulses are delivered to the same skin area several times during the same session, causing a gradual increase in absorption of the laser energy in the hair. This leads to effective hair removal even at lower
aser parameters than those required when single-pass hair removal is performed, making the treatment much more comfortable, often eliminating the need for cooling.
Using the Avalanche FRAC3® procedure, hair temperature is gradually increased with a sequence of low-energy pulses delivered to the same hair, effectivelly destroying the hair while maximizing treatment comfort.
Compared to the standard laser hair removal treatment concept, which requires medium-to-long laser pulse durations (LP, 15 – 50 ms), Fotona's short FRAC3 ® pulse, ideally 0.3 – 1.6 ms long exhibits the lowest hair damage thresholds, making this treatment more comfortable to the patient.
Measured dependence of the hair damage threshold. Hair removal is much more effective at FRAC3® laser pulse conditions, while keeping the epidermis safe.
The Fotona Dynamis/Spectro Line provides the optimal pulse profile, speed and power for quick and efficient hair removal using super-short FRAC3 ® pulses as well as standard long pulses. To treat large body areas of various shapes, SOE (Scanner Optimized Efficacy) technology can be used to quickly fill the entire treatment area with uniform energy at high laser pulse power densities, providing fast, precise, consistent and comfortable FRAC3 ® laser treatments. The result is a safer, uniform laser treatment without hot spots or energy loss.
