Undisclosed values are never estimated; “Not disclosed” is itself information for comparison.
Evidence
RF (radiofrequency) B — Home RF has a randomised split-face controlled trial (2022, 12 weeks, cosmetic on the other side) and an intraindividual controlled trial (2024) reporting wrinkle and dermal-thickness improvement. Output, temperature and protocol differ by device, so results do not transfer to a given product as-is.
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.

Mechanism vs result
Mechanism shownYes
Biological effect shownPartial
Visible cosmetic result shownPartial
“It heats tissue” is not “a visible lift is proven”. Home devices run far below clinic power for safety.
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.

Cost per studied protocol
No study of this model, so no cost per studied protocol is shown.
Cost per result is compared directly only between studies with the same endpoint, measurement method and duration. Ratios across different studies are not computed.
BUYING GUIDE
What to check before buying
RF (radiofrequency)
Output and temperature control matter most; gels and other consumables drive running cost.
FrequencyRF devices differ in frequency and electrode design.
Temperature controlA temperature sensor and cut-off are safety features.
Gel and consumable costCheck whether only a proprietary gel works and what a year costs.
Treatment timeMultiply time per area by sessions per week.
Safety contraindicationsCheck implants, pregnancy and other contraindications in the manual.
Protocol evidenceSee whether the product’s instructions match a studied protocol.
