Full Body Laser Hair Removal & Tattoo Removal Machine – 6Bar+FAC to 10Bar+FAC | ZENI

Full-Body Diode Laser Hair Removal

The diode handpiece targets melanin in the hair follicle across large body areas — legs, backs, chests, arms and bikini lines. Clinical data in Fitzpatrick IV–VI skin shows 57.9% mean hair reduction in the underarm and 56.7% in the chin after three sessions, with 100% patient satisfaction and no cases of keloid formation, scarring, infection or pigmentary changes[reference:14]. The 4–6 wavelength configuration allows operators to tailor treatment across different skin types and hair colors. The three-tier Bar/FAC matrix (6Bar+FAC, 10Bar, 10Bar+FAC) supports scalable coverage, from moderate-volume clinics to higher-throughput practices.

Picosecond Tattoo Removal

The dedicated picosecond handpiece delivers ultra-short pulses that shatter tattoo ink through a photoacoustic effect. Clinical comparisons demonstrate superior clearance versus nanosecond systems: 1064nm picosecond laser achieves 78.1% excellent clearance versus 54.4% for Q-switched nanosecond (p=0.029), with a median of 3 sessions versus 4 (p=0.020)[reference:15]. In the blue/black tattoo subgroup, picosecond 1064nm achieved 80% excellent clearance[reference:16]. A vacuum-assisted multimodal picosecond protocol reported mean pigment clearance exceeding 90% after a mean of 3.19 sessions, with no severe long-term adverse events[reference:17].

Pigment Removal & Skin Rejuvenation

The picosecond handpiece also addresses benign pigmented lesions, freckles, sun spots and uneven skin tone. The photoacoustic mechanism breaks pigment particles into smaller fragments for immune clearance. Depending on the wavelength configuration included with the selected package, the platform can support pigment-focused and skin rejuvenation protocols alongside hair and tattoo removal.

Scalable Treatment Capacity

The three-configuration matrix allows a clinic to choose the power tier that matches its actual volume. 6Bar+FAC is the entry point for clinics building their hair removal service. 10Bar is the choice for higher raw power where FAC is not required. 10Bar+FAC is the balanced option for clinics that need more power than 6Bar without sacrificing FAC beam collimation.

The Three Configurations Explained

6Bar+FAC is the entry configuration with FAC collimation for efficient energy delivery. 10Bar increases total power without FAC lenses, suitable for clinics prioritising raw output. 10Bar+FAC combines the higher Bar count with FAC collimation, maintaining approximately 89% fiber coupling efficiency while delivering more power than the 6Bar base[reference:18].

FAC Technology and Alignment Precision

FAC (Fast Axis Collimation) lenses collimate the fast axis of each laser bar, focusing the beam for efficient fiber coupling. Experimental data shows coupling efficiency can reach 89% with properly aligned FAC optics, and a 4μm displacement error can reduce efficiency by 78.5% — which is why the FAC-equipped configurations (6Bar+FAC, 10Bar+FAC) are worth considering over the non-FAC 10Bar option for clinics that prioritise energy efficiency and spot uniformity[reference:19][reference:20].

Picosecond Laser Mechanism

Picosecond lasers deliver pulses in the trillionths of a second, creating a photoacoustic pressure wave that shatters tattoo ink and pigment particles into smaller fragments. This mechanical fragmentation allows the body’s immune system to clear the particles more efficiently than purely photothermal nanosecond systems, which is why clinical comparisons consistently show higher excellent clearance rates and fewer sessions for picosecond lasers.

Per-handle output power, specific 4- and 6-wavelength combinations, picosecond wavelength options, pulse duration, spot size, screen size, cooling system, dimensions, weight and voltage should be confirmed in the model-specific specification sheet for the selected Bar/FAC configuration.

What are the three Bar/FAC configurations, and which should I choose?

The options are 6Bar+FAC (entry with FAC), 10Bar (higher power without FAC), and 10Bar+FAC (balanced power with FAC collimation). Choose 6Bar+FAC if you are building your hair removal service; 10Bar if raw power is the priority and FAC is not essential; 10Bar+FAC if you need more power than the base while maintaining the ~89% coupling efficiency that FAC provides.

What clinical evidence supports the hair removal and tattoo removal applications?

For hair removal: 808nm diode laser achieves 57.9% mean hair reduction after three sessions in Fitzpatrick IV–VI skin, with 100% patient satisfaction and no long-term complications[reference:21]. For tattoo removal: 1064nm picosecond laser achieves 78.1% excellent clearance versus 54.4% for nanosecond systems, with fewer median sessions (3 vs. 4, p=0.020)[reference:22]; in the blue/black tattoo subgroup, picosecond 1064nm achieved 80% excellent clearance[reference:23].

Why does FAC matter, and which configurations include it?

FAC lenses collimate the fast axis of each laser bar, improving fiber coupling efficiency to approximately 89%[reference:24]. A 4μm misalignment can reduce coupling efficiency by 78.5%[reference:25]. The 6Bar+FAC and 10Bar+FAC configurations include FAC; the 10Bar configuration does not.

How does this differ from ZENI’s other 5000W 2-in-1 models?

This model is deliberately focused on the 6Bar+FAC to 10Bar+FAC range — it does not offer a 16Bar flagship tier. For clinics where full-body hair removal is the core service and tattoo removal is complementary, this three-tier matrix covers the realistic power range without the cost of headroom that may never be used. Other models in the series offer 16Bar options, TEC cooling, or multi-tip configurations for more specialised needs.

What should I request with the quotation?

Ask for the model-specific specification sheet covering the selected Bar/FAC configuration, the specific wavelengths in the 4- and 6-wavelength options, picosecond wavelength configuration, per-handle output power, pulse duration, spot size, screen size, cooling system, dimensions, weight and voltage.
