Scar-Free Tattoo Removal (Deep Acoustic Wave™)

Deep Acoustic Wave™ (DAW) is LINLINE’s method for scar-free tattoo removal on the MULTILINE™ base unit. Instead of relying on a single, high-energy shot, DAW delivers nanosecond pulse-trains and uses a multi-wavelength palette (540, 694, 755, 1079 nm) to fragment ink layer-by-layer—opening a “dye-free gateway” so subsequent pulses reach deeper pigment with minimal trauma to skin.

Why DAW is different

Pulse-train physics, not single shots. Classic Q-switched methods use single pulses; DAW uses a sequence of nanosecond pulses where each pulse fragments the exposed layer so the next pulse penetrates deeper. This layer-by-layer approach helps clear dense, professional tattoos more efficiently and reduces thermal load on surrounding tissue.
Multi-wavelength selectivity for every color. On MULTILINE™, the clinician can switch to the optimal wavelength for each ink family—540 nm (warm reds/oranges), 694 nm (dark blues/greens), 755 nm (greens/teals/blues), 1079 nm (black/navy). The palette covers most multicolor designs.
Designed for scar-free outcomes. Nanosecond pulses generate photoacoustic effects that disrupt pigment while keeping heat diffusion short—minimizing collateral injury and helping preserve natural pigmentation.
Compared with other laser methods, DAW avoids overheating and mechanical skin injury linked to scarring. Pulse-trains with precise timing/power control enable deep action while keeping thermal/mechanical damage in check—a route to fewer sessions with lower PIH risk in suitable cases.

What a session is like

Feel: brief “snaps” as pulses pass; most clients tolerate DAW without anesthesia. Skin is not ablated; the goal is to act on ink, not healthy tissue.
Aftercare: you can usually resume normal activities immediately. Your clinician may suggest basic photoprotection to limit PIH risk while the skin settles.
Between sessions: fragmented particles are gradually cleared; you’ll see progressive lightening as treatment continues.

Practitioner essentials

Emitters & wavelengths (MULTILINE™): Nd:YAP/KTP 540/1079 nm, Ruby 694 nm, Alexandrite 755 nm (all Q-switched). This spread lets you match ink absorption and depth.
Pulse format: nanosecond pulses delivered in trains (timing and power adjusted for color/density)—enables layer-by-layer fragmentation and deeper reach.
Typical parameters (ranges): 3–6/8 mm spots; 4–30 J/cm² by color & zone; repetition up to ~5–10 Hz (see device presets).

Indications & areas

Professional & amateur tattoos, monochrome or multicolor, on body and face (observe standard safety for periorbital regions).
Black/navy outlines respond especially well to 1079 nm; greens/teals/blues to 755/694 nm; reds/oranges to 540 nm.

Results & course planning

Faster clearance by design. DAW’s layer-by-layer fragmentation is specifically described as leading to faster tattoo removal than other methods.
Sessions: number and spacing depend on ink density, colors, depth, location (professional vs amateur). Expect a series; visible lightening after each visit.
Goal: complete or near-complete clearance with preserved skin texture and natural pigmentation.

Benefits at a glance

For patients

Scar-free intent: method is designed to remove ink without harming skin, preserving texture and natural color.
Fewer, gentler passes: pulse-train strategy aims for faster clearance with less trauma.
Color-smart: multiple wavelengths mean better matching to your tattoo’s palette.

For practitioners

Controllable selectivity: adjust pulse timing/power and wavelength per color/depth.
Platform simplicity: run all DAW wavelengths on one MULTILINE™ base unit; switch emitters as needed.
Patient-friendly profile: the low scarring risk profile of Q-switched lasers with the efficiency of layer-by-layer fragmentation.

Key takeaway

Deep Acoustic Wave™ uses nanosecond pulse-trains and color-matched wavelengths to break ink layer-by-layer, creating a dye-free pathway to deeper pigment while protecting skin—a modern route to scar-free tattoo removal on the MULTILINE™ platform.
