Proprietary ACS-Laser™ Technology
How It Works
ACS-Laser™ (Adaptive Coagulation Selectivity) is a real-time pulse modulation algorithm that adjusts three parameters simultaneously:
Pulse Width - Calculated based on hair shaft diameter (50–200 μm) and Thermal Relaxation Time (TRT) of the target follicle
Fluence - Auto-scaled according to Fitzpatrick type (I–II: 40–80 J/cm²; V–VI: 20–40 J/cm²)
Cooling Duration - Pre/post-pulse cooling extends from 200 ms to 1,500 ms for darker skin
Clinical Advantage
Traditional diodes: Operator manually selects 1 of 5–8 preset protocols
SPIRIT-918: System analyzes 17 variables (skin tone sensor, hair density mapping, treatment history) and generates a custom protocol for each 1 cm² zone
Result: 40% reduction in adverse events (hyperpigmentation, burns) vs. fixed-pulse systems in a 12-month multi-center study (n=847 patients, Fitzpatrick IV–VI).
Clinical Indications (FDA-Cleared)
Primary Applications
Permanent hair reduction (all body areas, all hair colors except white/gray)
Pseudofolliculitis barbae (razor bumps, ingrown hairs)
Pilonidal sinus prevention (pre-surgical hair removal)
Hirsutism management (adjunct to hormonal therapy)
Adjunct Dermatological Uses
Acne vulgaris (mild-to-moderate inflammatory acne via sebaceous gland modulation)
Folliculitis decalvans (chronic scalp infection with scarring)
Acne keloidalis nuchae (posterior neck follicular inflammation)
Cosmetic Enhancement
Pre-surgical field preparation (reduces SSI risk by 30% vs. shaving alone)
Post-inflammatory hyperpigmentation (PIH) from follicular trauma
Skin texture refinement (mild collagen remodeling, secondary effect)
Skin Type Compatibility: Fitzpatrick I–VI

SPIRIT-918 Advantage: Integrated melanin sensor (diffuse reflectance spectroscopy) prevents operator error on ambiguous skin tones (e.g., Fitzpatrick III vs. IV).
Safety Architecture
1. Touch-to-Fire Activation
Laser emits only when full handpiece contact detected (capacitive pressure sensor)
Prevents accidental exposure to eyes, bystanders, or operator
2. Motion-Activated Pause
If handpiece moves >2 mm during pulse, emission stops instantly
Eliminates linear burns from operator tremor
3. Thermal Cutoff
If skin temperature exceeds 45°C (measured via IR sensor), system enters 30-second cooldown
Automatically logs event for quality assurance review
4. Redundant Interlocks
Footswitch + handpiece trigger + software confirmation required for each pulse
Complies with IEC 60601-2-22 (medical laser safety standard)

Frequently Asked Questions
Q: Can SPIRIT-918 treat white or gray hair?
A: No. Like all diode lasers, it targets melanin. White/gray hair requires electrolysis or Nd:YAG with carbon lotion (not included).
Q: How does ACS-Laser™ handle tanned patients?
A: Built-in melanin sensor re-assesses skin tone before each session. If tan detected, system reduces fluence by 15–30% automatically.
Q: What happens if I switch from another laser system?
A: We provide protocol conversion charts for transitioning patients mid-treatment (e.g., GentleLase → SPIRIT-918 equivalency).
Q: Is financing available?
A: Yes. Monthly payments from $1,190/month (60 months, $0 down, OAC through CareCredit Medical Capital).
