K7 Q‑Switched Nd:YAG Tattoo Removal Machine | Lefis

Intense pulsed light uses a broadband intense pulsed light source (here SPT 485–950 nm) rather than a single wavelength like many laser devices. The K7’s OPT-DP/SHR mode shapes and controls the pulse (“optimal pulse technology”) to deliver energy more evenly during ipl treatment/ipl therapy, helping reduce skin irritation while targeting unwanted hair, sun-related dark spots, and certain pigmented lesions.

SHR combines elements of laser hair removal with intense pulsed light technology in fast, sweeping passes (“In-Motion”). Energy at 485–950 nm is absorbed by melanin in dark hair, heating follicles through multiple low-fluence shots to gradually disable hair growth over treatment sessions with improved comfort on the treatment area.

Yes. The device integrates a Q-Switched Nd:YAG handpiece (1064/532 nm) for tattoo removal. 1064 nm targets darker inks (black/dark blue) deeper in tattooed skin, while 532 nm helps with brighter tones (reds/oranges). The Q-switch creates short, high-peak pulses that fragment ink pigment into smaller particles, which are then cleared naturally over multiple sessions.

The page indicates the K7 is “cleared for skin types I–VI and tanned skin.” In practice, parameters must be individualized—lower fluence, longer pulse width (here 1–40 ms), careful spot size (e.g., 8×40 mm or 10×50 mm), and strict sun exposure control are recommended, especially for darker skin to minimize side effects like skin discoloration.

With proper settings and treatment plan, IPL can provide dramatic lightening of age spots/solar lentigines, reduce the appearance of certain pigmented lesions, and improve overall tone. Most patients need more treatments spaced a few weeks apart; results vary by skin condition, depth of pigment, and aftercare (sun protection).

Typical, temporary effects include mild redness, warmth, or edema; occasionally very mild bleeding/mild bleeding or pinpoint crusting can occur after laser tattoo removal on dense pigment. Follow aftercare for the treated area (cooling, gentle skin care, avoid heat and sun exposure, apply sunscreen) and report any unusual reaction or allergic reaction to your healthcare provider.

Sensation varies (often compared to a rubber band snap). Many clinics use contact cooling and can apply a topical cream/local anesthetic for comfort on unwanted tattoo sites or small tattoos with dense pigment. The K7’s cooling (air + water + radiator + semiconductor) helps maintain comfort and protect skin cells surrounding the affected area.

Tattoo removal (Nd:YAG 1064/532 nm): depends on color mix, density, depth, and location; most tattoos require multiple sessions with time between visits for the body to clear fragmented particles. Hair removal (SHR 485–950 nm): typically a series across the growth cycle provides the best reduction; fewer sessions may be possible on lighter areas, but outcomes depend on skin types, skin tone, and hair thickness.

Avoid tanning and heavy sun exposure, stop over-the-counter photosensitizing skin care (per clinic guidance), and share your medical history and current meds with your healthcare provider. Arrive with clean skin—no makeup or active chemical peels on the treatment area—so energy is absorbed by the target (melanin or tattoo ink) rather than surface products.

SPT (485–950 nm) for IPL/SHR, Q-Switched Nd:YAG 1064/532 nm for tattoos Energy: SPT 1–50 J/cm²; Q-switch up to 1500 mJ (per page) Pulse width 1–40 ms, optimized for comfort and controlled heating 8×40 mm / 10×50 mm spot sizes for flexible coverage Multi-stage cooling (air + water + radiator + semiconductor) These support even delivery, reduce overheating risk, and help achieve targeted results on diverse skin types.
