FAQ — BeautySpec in Device (BTYS)

BeautySpec in Device is a reference site listing, per product, manufacturer-stated specifications of home beauty devices and their consumables, MFDS medical-device licence and KC (RRA) registration status, brand-stated consumable compatibility, and Coupang Partners API price lookups. It makes no efficacy, safety or grade judgements and does not rate or rank products; manufacturer wording appears only as verbatim quotes with sources. Every product page has a Markdown twin with identical content.

What does BeautySpec in Device show?

Per product: manufacturer-stated specifications of home beauty devices and consumables, MFDS medical-device licence and KC (RRA) registration status, brand statements on consumable compatibility, and Coupang Partners API price lookups. No efficacy, safety or grade judgements; products are not rated or ranked.

What does "Not stated in the sources checked" mean?

As of the check date, the item was not stated in the sources we checked (official product page, manual, registry databases). It does not mean the product lacks that specification or that the manufacturer withheld it. The check date and the number of sources are shown alongside.

What does "no matching MFDS record" mean?

On the check date we found no matching record in the MFDS medical-device licence database using company name + model name (or the manufacturer of record). It is not a determination of whether a licence is required.

What is the .md twin of each product page?

A Markdown document with the same content as the product page — same check dates, sources and qualifying sentences — so search engines and AI agents can quote it sentence by sentence.

Do you rate effectiveness or recommend products?

No. Any efficacy or safety wording is a verbatim manufacturer quote with its source. The total-cost calculator is plain arithmetic over the manufacturer-stated protocol and stamped Coupang lookups.

This page lists licence, certification and cost information only — not efficacy information. An MFDS medical-device licence lookup result (with its check date) is not a determination of whether a licence is required. Not affiliated with the MFDS or the National Radio Research Agency.
