Q-switched Nd:YAG laser for tattoo removal and pigmented lesion treatment
Description
The DEKA Synchro QS4 is an advanced Q-switched Nd:YAG laser platform designed primarily for multicoloured tattoo removal and the treatment of benign dermal and epidermal pigmented lesions. It combines four independently selectable Q-switched wavelengths (1064 nm, 532 nm, 585 nm and 650 nm) to effectively target a wide spectrum of ink colours and chromophores at different depths while minimising damage to surrounding tissue. The system delivers very short pulses on the order of nanoseconds with high peak power, producing a photoacoustic effect that fragments pigment particles which are then cleared by the body. Spot-size flexibility, optimised beam homogeneity and adjustable fluence allow tailoring of treatments according to skin type, pigment colour and lesion depth. The platform is widely used in aesthetic dermatology clinics and is supplied as a floor-standing console with articulated arm and interchangeable handpieces. The specific unit referenced has been serviced in October 2018, not used since, and has a reported lamp shot count of 505,621 shots, which is relevant for assessing remaining lamp life in a pre-owned system.
Bnefits
Four Q-switched wavelengths (1064 nm, 532 nm, 585 nm and 650 nm) in a single platform to treat a broad range of tattoo ink colours and benign pigmented lesions effectively.
High peak-power, ultra-short (approx. 6 ns) Q-switched pulses that generate a photoacoustic effect to fragment pigment with limited thermal diffusion to surrounding tissue.
Effective on multicoloured tattoos, including traditionally difficult colours such as green, light blue and purple, as well as dark and red inks.
Ability to treat both dermal and epidermal pigmented lesions with optimised energy delivery and spot-size selection.
Spot-size flexibility and homogeneous beam profile to improve treatment efficiency, coverage and clinical outcomes.
Designed for safety and minimal risk of scarring or hypopigmentation when used according to recommended parameters and indications.
Fast treatment times and optimised energy release to support high patient throughput in busy aesthetic dermatology practices.
Versatile platform suitable for carbon peel (photoacoustic skin toning) and certain rejuvenation procedures in addition to tattoo and pigmented lesion treatments.
CE-marked medical device manufactured under ISO 9001 and ISO 13485 quality management systems.
Indications
Professional and amateur multicoloured tattoo removal, including dark, red, green, blue and other colours, subject to wavelength availability and ink composition.
Removal or reduction of benign dermal and epidermal pigmented lesions (e.g. lentigines, café-au-lait spots and other benign hyperpigmentations) according to local labelling.
Treatment of residual or traumatic tattoos.
Adjunctive use in carbon peel or photoacoustic skin toning procedures where such use is supported by local protocols and regulations.
Other laser tattoo and pigment-related procedures as specified in the official Synchro QS4 operator’s manual and local regulatory approvals.
Composition
Energy source: Q-switched Nd:YAG laser with additional Q-switched KTP (frequency-doubled), yellow and red laser modules.
Pulse duration: ultra-short Q-switched pulses in the nanosecond range (around 6 ns as stated in promotional materials).
Emission mode: Q-switched, high-peak-power pulsed output designed for photoacoustic pigment fragmentation.
Spot sizes: multiple selectable spot sizes (e.g. approximately 2–6 mm, depending on handpiece configuration) for flexibility in treating different lesion sizes and depths.
Delivery system: articulated arm with interchangeable handpieces appropriate to wavelength and spot size.
Cooling and electronics integrated into a floor-standing console with user interface and safety interlocks.
Electrical supply: standard medical mains power (country-specific voltage and frequency; see operator manual for exact specifications).
Four separate Q-switched laser sources integrated into one system: Nd:YAG 1064 nm, KTP 532 nm, yellow 585 nm and red 650 nm.
Photoacoustic mechanism of action designed to shatter pigment particles while limiting surrounding tissue damage.
Multiple spot sizes and fluence ranges to adapt treatment parameters to ink colour, lesion depth and skin phototype.
Optimised beam homogeneity and energy distribution for consistent results across the treatment area.
Console-based system with touchscreen or similar user interface providing preset and custom treatment parameters.
Packaging
Floor-standing laser console housing the Q-switched laser sources, control electronics and cooling system.
Articulated delivery arm for precise positioning and ergonomic handling during procedures.
Interchangeable handpieces for different wavelengths and spot sizes, as supplied with the chosen configuration.
Footswitch for laser activation in accordance with standard laser safety practice.
Key-operated main switch and emergency stop button on the console.
Manufacturer-supplied operator’s manual, safety documentation and basic accessories.
Laser safety eyewear for patient, operator and assistants tailored to the device’s wavelengths (supplied per distributor or clinic procurement).
For the pre-owned unit referenced: original components as above, subject to confirmation of included handpieces, accessories and documentation by the seller.
Usage
Use only by appropriately trained and licensed medical professionals familiar with Q-switched laser physics, tattoo and pigment removal techniques and applicable regulations.
Before treatment, obtain a full medical history, evaluate skin type, tattoo or lesion characteristics and rule out contraindications; obtain informed consent.
Select the appropriate wavelength based on tattoo ink colour or lesion chromophore (e.g. 1064 nm for dark inks and deeper pigments, 532 nm for red/superficial pigments, 585/650 nm for certain green, blue or resistant colours).
Choose spot size and fluence according to lesion size, depth, skin phototype and clinical guidelines; begin with conservative settings and perform test spots where indicated.
Provide suitable laser safety eyewear for patient and all personnel; display laser warning signs and control room access in compliance with laser safety standards.
Clean the treatment area, remove any topical products and, if necessary, apply topical or local anaesthesia following clinic protocols.
Position the handpiece perpendicular to the skin at the recommended distance; ensure proper coupling and avoid overlapping pulses excessively beyond recommended parameters.
Monitor tissue response (e.g. whitening, mild pinpoint bleeding) and adjust parameters within safe limits to optimise clinical effect while minimising risk of adverse events.
After treatment, apply appropriate post-laser care (cooling, topical soothing products, non-occlusive dressings if needed) and instruct the patient on wound care, sun avoidance and photoprotection.
Schedule follow-up sessions as needed; intervals are commonly several weeks apart to allow sufficient time for pigment clearance and tissue recovery.
For the pre-owned device described (serviced October 2018, unused since, lamp shot count 505,621), verify full functional status, lamp life, calibration and safety checks via qualified technical service before clinical use.
Contraindications
Active infection, dermatitis or open wounds in the intended treatment area.
Known photosensitivity disorders or use of photosensitising medications that significantly increase the risk of adverse reactions.
History of abnormal scarring, such as keloids or hypertrophic scars, without careful risk–benefit assessment.
Recent intense sun exposure or tanning of the treatment area, which increases the risk of dyspigmentation.
Uncontrolled systemic diseases (e.g. poorly controlled diabetes, bleeding disorders) that may impair healing or increase risk of complications.
Pregnancy or breastfeeding where elective aesthetic laser procedures are discouraged by local policy or regulatory labelling.
Inability or unwillingness to comply with aftercare instructions, especially strict photoprotection.
Any other contraindications or warnings specified in the official DEKA Synchro QS4 operator’s manual and local regulatory information.
Adverse Effects
Transient pain or discomfort during treatment, often described as snapping or stinging sensations.
Erythema, oedema and mild to moderate inflammation in the treated area immediately following the procedure.
Crusting, blistering or superficial erosions, particularly at higher fluences or on sensitive skin.
Temporary changes in skin pigmentation such as post-inflammatory hyperpigmentation or hypopigmentation, especially in darker phototypes or after sun exposure.
Risk of infection (bacterial, viral or fungal) if treated areas are not properly cared for during healing.
Rare risk of scarring, textural changes or persistent dyschromia, particularly with inappropriate parameter selection or inadequate aftercare.
Purpura or pinpoint bleeding in certain treatment settings.
Eye injury if appropriate wavelength-specific protective eyewear and laser safety protocols are not strictly followed.
Storage Conditions
Install and store the device in a clean, dry, temperature-controlled clinical environment within the operating conditions specified in the operator’s manual (typically standard indoor room temperature and non-condensing humidity).
Position the floor-standing console on a stable, level surface; lock castors when the system is in use or parked.
Protect the articulated arm, handpieces and optics from dust, mechanical shock and contamination; use protective covers when the system is not in use.
Disconnect from mains power during extended periods of non-use or when performing maintenance, in accordance with manufacturer recommendations.
Follow all additional storage, transport and environmental conditions specified in official DEKA documentation, including limitations on vibration, impact and exposure to corrosive or flammable atmospheres.
Duration
Typical treatment sessions for small to medium tattoos or pigmented lesions range from approximately 10 to 30 minutes, depending on lesion size, number of passes, wavelengths used and patient preparation.
Onset
Initial lightening of tattoos or pigmented lesions is often visible after the first session once post-treatment erythema and crusting settle, typically over 1\u20133 weeks; progressive clearance generally occurs over multiple sessions spaced several weeks apart as fragmented pigment is cleared by the body.
