The Mona SQ-1 is a commercial Q-switched Nd:YAG laser system designed for clinics, medical spas and beauty centers. It treats tattoo removal (dark and some light inks), skin rejuvenation, pigmentation (sun spots, freckles, age spots), hair reduction (especially darker hair on lighter skin), acne and certain acne scars.
No. The Mona SQ-1 is a Q-switched Nd:YAG laser with pulse duration of approximately 8±2 nanoseconds (ns). Picosecond lasers have pulse durations in the picosecond range (<1 ns) and are a different class of device.
The system provides two wavelengths: 1064 nm (best for deeper layers, dark inks like black/blue/green, deep pigmentation and skin rejuvenation) and 532 nm (targets more superficial pigments and lighter tattoo colors such as red/orange and certain superficial pigmentation).
Output energy is adjustable: 1064 nm from 80–1600 mJ and 532 nm from 40–800 mJ. Pulse duration is 8±2 ns and repetition rate is adjustable from 1 to 10 Hz, allowing customization for different indications and skin types.
1064 nm Nd:YAG is generally safer for darker skin types (Fitzpatrick III–VI) because of its deeper penetration and lower melanin absorption. 532 nm is more suited to lighter skin types for superficial pigments. Always perform a test spot and adjust settings based on patient response.
Tattoo removal depends on ink color, depth, density and patient factors. Typical ranges are 4–12+ sessions. Sessions are commonly scheduled 6–12 weeks apart to allow pigment clearance and tissue recovery. Professional assessment is required for an accurate treatment plan.
Common short-term effects include redness, swelling, mild discomfort, pinpoint bleeding, crusting or blistering. Pigment changes (temporary hyper- or hypopigmentation) can occur, especially with inadequate aftercare or in darker skin types. Scarring is uncommon with correct settings and technique. Downtime typically ranges from a few days to a couple of weeks depending on treatment intensity.
Pre-treatment: avoid recent tanning, certain photosensitizing medications, and active infections; perform a patch test if uncertain. Post-treatment: keep the area clean, avoid direct sun exposure, use broad-spectrum sunscreen, follow wound care instructions (cooling, topical ointments if advised), and avoid picking at crusts. Specific protocols should follow manufacturer and clinic guidelines.
Laser energy is delivered through a 7-jointed articulated arm for flexible maneuvering and precise targeting. A 650 nm red guide beam provides an aiming reference so the operator can position the beam accurately before firing.
The system uses a closed-cycle water-to-air heat exchanger to maintain optimal operating temperature and reduce thermal risk during procedures. Standard safety procedures include the use of appropriate eye protection for patient and operator, emergency stop controls, and trained operator protocols. Always follow local laser safety regulations.
Regular maintenance typically includes checking and replacing filters as needed, monitoring and replacing coolant or service of the closed-cycle cooling system per manufacturer instructions, inspecting and tightening the articulated arm and optics, keeping the touch screen and exterior clean, and scheduling periodic professional servicing/calibration. Refer to the supplied service manual for exact intervals.
The Mona SQ-1 should be operated only by licensed and trained professionals (dermatologists, licensed laser technicians or medical personnel) who have completed hands-on training on Nd:YAG Q-switched lasers, patient selection, parameter selection and safety protocols. Local regulations may mandate specific certifications.
Contraindications commonly include pregnancy, active skin infections in the treatment area, recent isotretinoin use (within the timeframe recommended by guidance), uncontrolled medical conditions, and certain photosensitive medications. Also avoid treating over tattoos made of unknown or potentially hazardous pigments (e.g., some household inks). Always perform a medical and medication history and follow contraindication guidance from the manufacturer and local regulations.
