We're seeing these go mostly to smaller med-spas and dermatology practices that already do microneedling or chemicla peels and want to add something for post-procedure recovery or maintenance — the ultrasonic vibration at 300 million per second is basically mechanical agitation at a frequency that doesn't heat tissue teh way RF does, so it's safe for sensitive or post-laser skin.
It runs on 110V or 220V without a transformer, which is handy if you're traveling to trade shows or have multiple clinic locations, and automatic shut-off kicks in after about 15 minutes of continuous use — we've had a few units come back because users didn't realize it was a timed safety feature and thought it was broken.
What you get in the box is the handpiece with a standard flat probe, a neck strap, and a power cord — no gel or spare probes, so you'll need to order those seprately (usually 2-4 weeks lead time on replacement probes, depending on stock).
The scar reduction thing works better on newer hypertrophic scars than on old atrophic ones, actually — the mechanical vibration seems to help soften collagen bundles, but for deep ice-pick acne scars you'd still want subcision or TCA cross, this is more of an adjunct.
Also, the treatment time per area is 5 to 15 minutes, and we've found that most buyers go with the 10-minute setting for the face — any longer and the gel starts to dry out and you lose coupling effiency, which the COA won't tell you but a quick test with a patch of skin will.
We can start with a single unit for testing, but bulk orders of 10+ get better per-unit pricing.
Stocked items ship within 3-5 business days. Custom packaging adds about 2 weeks.
Yes, the WD-169A comes with CE certification. FDA documentation is available on request.
The frequency is fixed for optimal performance, but you control treatment time from 5 to 15 minutes per area to tailor intensity.
The unit is packed in a 30x25x20 cm box weighing about 2.5 kg. We can share exact dimensions with your shipping address for a quote.
