Anti-cellulite leggings: what consumer tests and studies really say
Short answer: as far as we know, neither 60 Millions de consommateurs nor UFC-Que Choisir, the two big French consumer magazines, has published a test of anti-cellulite leggings. Both tested creams, with results well below the promises. Studies on compression garments show a modest, short-lived smoothing effect, not cellulite disappearing. Here is what consumer tests and studies really say, with sources.
We sell anti-cellulite leggings, so it makes sense to check what we write here: every key claim links to its source.
The short answer
As far as we know, as of 8 October 2026, neither 60 Millions de consommateurs nor UFC-Que Choisir, the two big French consumer magazines, has published a test of anti-cellulite leggings. Both have tested anti-cellulite creams: UFC-Que Choisir found no real improvement, and 60 Millions pointed to the gap between the promises and the effects. Neither has taken a position on leggings, for or against. If a brand says its legging was "tested by a consumer magazine", ask for the issue number.
Why French sources? Leonie & Co is a French brand, and these are the closest published consumer tests to the subject that we found. If a consumer association in your country publishes a test, that is the first source to read.
60 Millions de consommateurs: a report on cellulite, no legging test
We searched the 60 Millions de consommateurs website for the French words for legging, tights, cosmetotextile, shapewear and slimming garment. No article or comparative test covers an anti-cellulite textile.
What the magazine did publish is a report titled "Cellulite : des armes (un peu) efficaces" (cellulite: weapons that work, a little), posted on 25 May 2022, with a test of 9 slimming creams in the June 2022 issue. The report reviews diet, supplements, skin-rolling massage, exercise, radiofrequency and cryolipolysis. It does not mention any garment.
Two points from that report are worth remembering:
- On creams, the magazine points to the gap between what manufacturers promise and what actually happens.
- The only massage it considers validated by studies is manual lymphatic drainage, and its effects do not last.
UFC-Que Choisir: 9 creams tested in 2018, no leggings
In April 2018, Que Choisir tested 9 anti-cellulite creams from major brands. The protocol was rigorous: 30 women, two applications a day for a month, double blind, with a dermatologist, thermography and a tape measure. The verdict of the investigation: no real improvement, and differences in thigh circumference of 2.5 mm at most.
Que Choisir has not tested leggings. Its ingredient database does include an entry for a slimming legging with microencapsulated active ingredients, but it analyses the composition (the allergens), not whether the legging works.
The same 2018 report advises avoiding "clothes that are too tight" when cellulite is linked to poor circulation. That advice applies to our leggings too: a legging that is too small squeezes where it should support. Take your true size, and if in doubt, go one size up.
Which anti-cellulite leggings work best according to tests?
We have not found any independent test that would let us say so today. Looking for a consumer magazine's verdict is still the right instinct: anti-cellulite leggings are sold with strong promises, and a neutral opinion is worth more than a product page. Without such a test, three independent sources exist: checks by the French consumer authority, advertising rules and scientific studies.
What the authorities and advertising rules say
The DGCCRF, the French consumer protection authority, inspected so-called technical textiles in 2021. These checks covered all such textiles, not anti-cellulite leggings specifically. In its investigation "Textiles techniques : entre innovation et surenchère" (technical textiles: between innovation and overclaiming), published on 3 June 2022, 36% of the 67 businesses inspected had irregularities. The rule it restates is simple: a technical property can only be claimed if it rests on verifiable scientific evidence.
French advertising rules, set by the ARPP, the advertising industry's self-regulatory body in France (ARPP "Produits cosmétiques" recommendation), accept the word "anti-cellulite" when it refers to how the skin looks: smoother, firmer. They forbid promising weight loss, or claiming to prevent or treat cellulite. That is the rule we follow in our articles: "smooths the look of the skin", not "eliminates cellulite".
What studies say about garments and cellulite
Studies exist, but they are few and small.
| Study | What was tested | What was observed | Limitations |
|---|---|---|---|
| Bagatin et al., 2013 | Compression tights worn by 30 women | Slight effect on the look of cellulite, better quality of life | No group without compression |
| Kiely et al., 2023 | Compression garment worn for 4 weeks by 18 women | Higher satisfaction, slightly less water under the skin, weight unchanged | No control group, link with the manufacturer |
| Luebberding et al., 2015 | Review of 67 studies on all treatments | No clear evidence of good efficacy, whatever the treatment | Few studies look at garments |
What comes up from one study to the next: a modest, short-lived smoothing effect, and women who feel more comfortable in their bodies. No study shows weight loss or cellulite disappearing. And no independent study has yet been published on 3D-knit leggings without active ingredients, like ours.
How to judge an anti-cellulite legging without an official test
Until you find an independent test, here are the questions to ask any brand, ours included:
- What exactly does it promise? "Smooths the look of the skin while worn" is honest. "Melts cellulite away" or "-3 cm in 15 days" is not, unless there is published evidence.
- Which technology? A textured knit that massages and holds, graduated compression, or microcapsules of active ingredients that wear off over the washes. These are not the same products.
- Which sizes? A legging that is too tight is uncomfortable and counterproductive. Check the size guide and the range on offer.
- Which reviews, and where? A rating on an independent platform such as Trustpilot, with the number of reviews and the negative reviews visible, is worth more than stars on the product page.
- What are the return conditions? How long you have, and who pays for the return.
To read anti-cellulite leggings reviews with these criteria in mind, we compared seven brands in our comparison of anti-cellulite leggings. And we explain what a legging can and cannot do in do anti-cellulite leggings work?
Our 3D legging relies on a textured knit that gently massages the skin with every movement, light compression and a shaping effect, from S to 5XL. It smooths the look of the skin while you wear it and makes your legs feel lighter. It does not make cellulite disappear.
Frequently asked questions
Has any consumer magazine tested anti-cellulite leggings?
Not in France, as far as we know. As of 8 October 2026, neither 60 Millions de consommateurs nor UFC-Que Choisir, the two big French consumer magazines, had published a test of anti-cellulite leggings. The 60 Millions report on cellulite of 25 May 2022 covers creams, exercise and in-clinic techniques, and does not mention any garment.
Do anti-cellulite leggings work according to tests?
As far as we know, neither of these French consumer magazines has published a test of them to date. The few scientific studies, on 18 to 30 women, show a modest, short-lived smoothing effect and greater satisfaction. None shows cellulite disappearing or weight loss.
What do doctors think of anti-cellulite leggings?
Reviews of the medical literature (Luebberding et al. 2015, Gabriel et al. 2023) conclude that no cellulite treatment has clearly demonstrated efficacy, garments included, and that the improvements observed are short-lived. A legging can improve comfort and how your legs look. It is not a treatment.
How long do you need to wear an anti-cellulite legging to see an effect?
The shaping effect shows as soon as you put it on, since the legging holds the tissue, and it does not last once you take it off. Studies followed women for about 4 weeks of daily wear and saw only modest changes. Be wary of promises of measurable results in a few days.
What is the difference between graduated compression and 3D knit?
Graduated compression is tighter at the ankle than at the thigh to help blood flow back up the veins, like a compression stocking. 3D knit is a textured knit that gently massages the skin with every movement and visually smooths the silhouette, with softer compression. The first is mainly for heavy legs, the second for comfort and appearance.
Do anti-cellulite leggings help you lose weight?
No. No study shows weight loss with a legging, and advertising rules forbid promising it. It can make your silhouette look slimmer while you wear it by holding the tissue, which is a visual effect.
How do you spot a good-quality anti-cellulite legging?
Look for measured, verifiable promises, clearly explained technology, a wide size range with an accurate size guide, reviews on an independent platform with the negative reviews visible, and clear return conditions. Also check in the reviews whether it keeps its shape after repeated washing.
In short
60 Millions de consommateurs and UFC-Que Choisir have not tested anti-cellulite leggings. They tested creams, with results well below the promises. Studies on garments show a modest, short-lived smoothing effect and women who feel more at ease, nothing more. A good anti-cellulite legging is therefore a comfortable garment that improves how your legs look, not a treatment. Choose it on criteria you can check.
