Technology

Ultrasound (incl. focused) · general tech evidence D

Ultrasound energy focused at a set depth under the skin to create heat

Dose transparency · None (0/3)

FrequencyNot disclosed

Output / energyNot disclosed

Focal depthNot disclosed

Undisclosed values are never estimated; “Not disclosed” is itself information for comparison.

Evidence

Ultrasound (incl. focused) D — Clinic focused ultrasound (HIFU/MFU) is well studied, but we found no controlled studies of low-power home devices.

Product grade (studies of this model only): A ≥2 independent RCTs (30+ each) · B one RCT or two controlled studies · C uncontrolled, small or maker-linked. Without them the technology grade is shown, except for multi-function devices and LED without published wavelengths. Without a published dose, study results cannot be assumed to apply to this product.

Actual output is not published, so the technology evidence cannot be assumed to apply to this product. Multi-function device studies are never reused as evidence for a single technology.

Clinical studies

Studies of this model

No public product-level study found. We will add any public study the maker points to.

Marketing claim vs evidence

ClaimManufacturer claim“Produces collagen”

EvidenceNo public study found

Measured resultNone

Independent replicationUnknown

Mechanism vs result

Mechanism shownYes

Biological effect shownPartial

Visible cosmetic result shownUnknown

“Same principle as the clinic” does not mean the same effect; the energy delivered differs.

Outcome susceptibility to placebo / natural variation

High

This does not mean the product has no effect. It shows how easily the reported result could be influenced by expectation, time, swelling, hydration or measurement conditions.

No study compared against a control, so reported change cannot be separated from the factors below.

Natural skin variation · Hydration · Swelling · Lighting · Camera angle · Make-up · Weight change · Sleep · Menstrual cycle · Skincare used alongside · Massage effect

Before / after reliability

Unknown

A: controlled conditions + objective device measurement + blinded assessment · B: mostly controlled · C: partly · D: large lighting/angle differences · F: marketing image. Only photos checked for lighting, camera, angle, expression and distance are graded; photos alone never confirm an effect.

Owner answers are user reports, not findings. Verified and unverified answers are separated; under 10 responses only counts are shown, under 30 a small-sample note is added.

Treatment burden

Session time not confirmed from official instructions or a study protocol.

Must you keep using it to maintain results?Unknown

Consumable lock-inUnknown

If the effect is small, this time is a cost too. Maintenance needs are shown only when sourced.

Pricing

Retail price₩1,590,000Launch price

Estimated markupNot shown — no BOM or factory-cost basis

Launch price, January 2023; current price may differ · 2023-01-10

“Estimated markup” is used only with a real BOM or factory-cost basis. This product has none, so no number is invented. The price premium above is a ratio of real retail prices.
