“melts fat” — High risk

Updated 2026-08-15 · Risk-term list version 2026-08-15c

Why it is risky

A stronger physiological claim than "burn fat" and one platforms reject on sight.

Sweating more is not the same as burning fat, and this family of phrasing turns a wearing sensation into a physiological effect. It is where shapewear and "sauna" garments get taken down most often.

What to say instead

There is no safe substitute. This is not a wording problem — the thing it promises is something a garment cannot do, so the fix is to delete the sentence, not to find a softer way to say it.

Where this phrasing usually shows up

Across the samples we have scanned, this family shows up in these places, most common first:

• Listing bullets
• Text burned into the main image
• What the creator says on camera
• Packaging and hang-tag copy

The last two are the ones people miss: what the creator says on camera and replies in the comments. Neither lives in your documents, both are visible to the platform, and both are harder to fix after the fact.

Other phrasings in the same family

Fixing one line often introduces another from the same family. The rest of this family:

What the regulator said

These are the regulator’s own words, not our paraphrase. This family has enforcement that matches the category exactly — not general advertising law, but a case about shapewear undergarments.

the law draws a sharp distinction between a suggestion that a certain kind of underwear may help people look or feel better while wearing it vs. an affirmative representation (especially one supposedly supported with scientific evidence) that it will reduce cellulite, shrink hips or thighs, and destroy fat.

This is the silhouette-versus-body line, drawn by the regulator itself: "looks smoother under clothes" sits on one side, "burns fat, takes inches off, clears cellulite" on the other, and the second side needs evidence you can produce. The two phrases actually charged are worth holding your own listing against: "Lose 2 inches off hips and 1 inch off thighs in less than a month . . . without effort" and "caffeine metabolizes and dehydrates fat cells".

the companies are banned from claiming that any garment that contains any drug or cosmetic causes substantial weight or fat loss or a substantial reduction in body size. The companies also are prohibited from making claims that any drug or cosmetic reduces or eliminates cellulite or reduces body fat, unless they are not misleading and can be substantiated by competent and reliable scientific evidence.

The two companies paid $1.3 million and $230,000 respectively for consumer refunds. Note the tail of the order — "unless ... competent and reliable scientific evidence": these claims are not banned outright, they are banned when unsubstantiated. Most cross-border sellers cannot produce evidence at that standard, which is why this list treats them as high risk. That is a risk judgement, not a legal determination.
