There is first the seduction of a phrase. A thinner nose. Clearer skin. On TikTok, the narrative settles in like many others, between confessional tone, before-and-after and a quick promise. Then reality returns, heavy, medical, regulatory. On March 12, 2026, the ANSM warned about the promotion of isotretinoin-based medicines for unauthorized cosmetic uses. The health authority reminds that these treatments are intended for severe acne when other options have failed, that they do not change the shape of the nose and that they expose users to serious accutane side effects and isotrétinoin risks.
The Rumor Of A Fixed Face Without Surgery
The power of this sequence lies in its simplicity. In the videos, no elaborate demonstration is needed. Just a close-up of a face, a memory of a treatment, a comment launched like a confidence. The promise is all the more effective because it seems modest. It is not about proclaiming a complete transformation, but rather making a slight correction to reality. It’s a facial detail, precisely that sensitive point where so many complexes settle.
According to several press articles published on March 12 and 13, 2026, the rumor amplified. It was fueled by personal testimonials, but also comparative photos and a catchy formula. That formula evoked a sort of free rhinoplasty. The success of these contents comes not only from their virality. It comes from their apparent sincerity. Internet users tell what they believe they saw on their own face. In the economy of social networks, this type of narrative often counts as proof.
This mechanism gained even more visibility when Kendall Jenner’s name was associated with the theory. According to press reports, the celebrity suggested that an Accutane-type treatment based on isotrétinoin could have slimmed the nose. This sequence served as an amplifier. Yet it brings no scientific validation. It mainly shows the cultural weight of a famous voice in creating an ordinary belief.
What The ANSM Says About Isotrétinoin
Substantively, the agency’s message is clear. The products involved include Roaccutane 0.05% gel as well as Isotrétinoïne Acnétrait, Contracné, Curacné and Procuta capsules, brand names of isotrétinoin. According to the ANSM, these medicines are currently being promoted on social networks for cosmetic purposes, outside their authorized therapeutic indications.
The authority makes a central point: these medicines do not change the shape of the nose. On the contrary, they can alter skin quality. The impression of a more refined face, relayed in several articles, could at best be a temporary visual effect. This is linked to skin drying, chapped lips and nosebleeds. Furthermore, a reduction in inflammation or a decrease in sebum can also be the cause. In short, some interpret a lasting transformation of the nose, but this does not correspond to a bony change. According to the authorities and specialists’ explanations cited in the press, there is no change in the cartilage.
The ANSM also reminds that the sale and promotion of medicines on the internet without authorization are illegal. This reminder is not a procedural detail. It marks a boundary. On one side, a regulated medicine, subject to prescription rules. On the other, digital circulation blurs uses, reduces precautions and transforms care into a product of projection.
A Potent Drug, Far From A Simple Beauty Gesture
The other, more serious issue lies in the very nature of isotrétinoïne. This treatment is not trivial. According to the ANSM, it can cause serious accutane permanent side effects and isotrétinoin adverse effects, which may persist after discontinuation, including at low doses. The agency notably cites psychiatric disorders. Roaccutane, depression and mood disorders are among the risks reported during treatment or after its cessation.
It also reminds of the high teratogenic risk in case of pregnancy. On this point, caution must remain absolute. In case of isotrétinoin and pregnancy, the risk of birth defects remains major. Known teratogenicity and the absolute contraindication during pregnancy require maximum vigilance. Contraception must be in place before treatment begins, continued during its course and maintained until one month after stopping. The ANSM also mentions other risks, notably sun exposure under isotrétinoin, liver damage, skin problems with significant dryness or possible acne worsening, visual disturbances, muscle and joint pain, as well as intestinal disorders, including constipation.
Public messaging here reiterates something elementary: a medicine prescribed for a severe condition does not become less dangerous because it is filmed in a trendy format. Social networks tend to flatten the hierarchy of objects. A cream, a filter, a supplement, a medicine: everything can end up in the same feed. But not everything carries the same weight or the same risk.
Why The Face Becomes A Ground For Belief
This affair says a lot about our time. The face has become a territory of continuous surveillance. It is observed, retouched, commented on, compared. Platforms have intensified this tension by turning every detail into a subject of debate: skin texture, the line of the nose, facial contour, dark circles, radiance. In this climate, the promise of a discreet improvement seems irresistible.
The success of the slim-nose theory is therefore not only medically false according to the ANSM. It is socially understandable. It responds to a fatigue with the imperfect face. It also matches a culture of constant optimization, where products are expected to do more than what they are supposed to do.
The novelty is that this belief no longer passes only through classic advertising. It spreads through close-range narratives. One person tells their case. Another confirms. A celebrity suggests she observed the same effect. And little by little, the idea acquires the status of evidence. It is not proof that convinces. It is repetition.
The phenomenon goes beyond France. In Switzerland, RTS already noted on July 29, 2025, a new wave of Roaccutane popularity on TikTok and social networks, with associated health concerns. In other words, the French episode does not come out of nowhere. It is part of a transnational circulation of aesthetic narratives around an old, powerful and tightly regulated medicine.
The Return Of The Medical Boundary
Who can prescribe Roaccutane? Only dermatologists can start it. Faced with this trivialization, the ANSM re-establishes a clear line. Only dermatologists can initiate oral isotrétinoin treatment, within the framework of severe acne forms resistant to other treatments. Monitoring must be strict. For women of childbearing age, the initial prescription includes a care agreement. Each renewal is limited to one month.
This regulatory reminder has a broader significance than it appears. It reaffirms that a medicine is not a symbolic language meant to correct diffuse dissatisfaction. It is a therapeutic tool, handled within a precise framework, for an expected benefit that must remain greater than the risk.
The era often blurs this boundary. Well-being meets performance. Care meets appearance. Medicine meets narrative. The March 2026 alert reminds that limits still exist, and they are not bureaucratic whims: they are built around patient safety.
At bottom, this sequence tells less about a medicine than about a climate. It shows how a society fascinated by image can re-enchant a heavy product by turning it into an aesthetic shortcut. It also shows that official health messaging, often judged cold or late, remains indispensable. Indeed, it is crucial when viral false common sense takes over. Between the promise of a thinner nose and the reality of a risky treatment, the gap is immense. It is in that gap that a very concrete part of public health is being played today.
Baby and Roaccutane: a major risk of birth defects during pregnancy remains one of the most decisive reminders of this health alert.
