Is a slimmer nose a surprising side effect of clear skin? A viral trend on TikTok suggests Roaccutane, a powerful acne medication, can subtly reshape the nose. The claim gained traction when model Kendall Jenner recently discussed her teenage experience with the drug, fueling speculation that it altered her facial features. But can an acne treatment really change your bone structure?

Thousands are sharing “before-and-after” photos on TikTok, attributing a noticeably thinner nose to Roaccutane treatment. Comments like “My nose was wide, now it is thin,” “I thought it was weight loss but no,” and “It’s really a free rhinoplasty” are common. Jenner herself alluded to the effect in the podcast In Your Dreams With Owen Thiele, stating her anti-acne treatment as a teenager made her nose thinner.
An Exaggerated Inflammatory Reaction
Professor Anne Dompmartin, dermatologist and head of the dermatology-venereology department at Caen University Hospital, firmly dismisses the claim. “It’s false information,” she states. Medically, Roaccutane—derived from vitamin A—is well-understood. It works by regulating skin renewal and reducing sebum production. “It has a role on the sebaceous glands of the face, but not on the volume,” she specifies. A shrinking effect might be perceived if a large cyst reduces in size as inflammation subsides, but the drug doesn’t alter the underlying nasal structure. “It’s like when you have a small abscess on your arm, when the inflammation disappears, your arm is not smaller.”
So, where does this impression of a slimmer nose come from? Professor Dompmartin explains it’s likely due to improvements in skin condition. “When you have acne, you have skin too oily. Roaccutane will dry out the skin, which reduces sebum production and improves inflammation, so on this point the appearance changes. But it has no action on the bone or cartilaginous structure. It never changed the shape of any organ. Neither the nose, nor the shoulders, nor the cheeks, nor the chin. Never.”
Social media presentation also plays a role. “There is a way to take photos,” recalls the dermatologist. Factors like lighting, angle, distance, and makeup can significantly influence how a face appears in images.
An Unusual Location for Acne
Professor Dompmartin also points out that Jenner’s reported acne location is atypical. “Serious acne often occurs on the mandibles, lower jaw, neck, back, legs but less frequently on the nose.” She also questions the severity of the skin issues presented in Jenner’s photos. “This woman has no acne scars anywhere. In my opinion, she has a fine nose by nature.”
Treatment Requires Medical Supervision
Beyond the misinformation, Professor Dompmartin stresses the importance of responsible medication use. Roaccutane is a prescription drug for severe acne and “This treatment generally lasts 6 to 8 months and requires strict medical supervision,” she emphasizes. It’s not suitable for everyone, and alternative treatments should be explored with a healthcare professional first.
