Rhinophyma: thickened nose skin in rosacea and its treatment

What is rhinophyma?

The ROSCO panel defines phymatous changes as facial skin thickening from fibrosis, enlarged oil (sebaceous) glands or both. They most often affect the nose, where they can give a bulbous shape, and they are one of the two features that diagnose rosacea on their own.^[1][2] Rhinophyma is the name for this thickening on the nose; the AAD notes that phyma can also form on the chin, forehead, eyelids and ears (AAD treatment page, checked 24 October 2026).

Under the microscope, rhinophyma shows enlarged oil glands, widened follicle openings plugged with keratin, and dense fibrous tissue (fibrosis) in the dermis, usually across the lower two-thirds of the nose.^[3] In the four-subtype classification of the National Rosacea Society, this thickening is the phymatous subtype (phymatous rosacea).^[4] In 2017 the ROSCO panel agreed to move rosacea diagnosis and classification from subtypes to a phenotype-based approach.^[2]

Who gets rhinophyma?

According to the AAD, fewer people with rosacea develop thickened skin, men more often than women, and it can occur when rosacea goes untreated for years (AAD symptoms page, checked 24 October 2026), and the NHS describes thickened skin, mainly on the nose, that usually appears after many years (NHS, checked 24 October 2026).

A 2026 systematic review pooled 149 case reports, case series and observational studies covering 2,720 patients: 58.9% were men, the mean age was 62.9 years and 61% had severe rhinophyma. Older age and male sex were the main risk factors.^[5] A 2026 report of two men, aged 65 and 76, describes rosacea present for more than 10 years and noses that had enlarged over the previous five to seven years.^[6]

Rhinophyma does not always follow obvious rosacea. A 2026 case report notes that it can occur without overt rosacea and that not all rosacea progresses to thickening; its 71-year-old patient had no history of flushing, redness or pustules.^[3]

Rhinophyma treatment by grade

Severity decides the treatment. A 2026 evidence review of studies published from 1990 to 2025 found that tablets such as doxycycline and isotretinoin help mainly in early, inflammatory disease (Clark Grade I), while established, fibrotic rhinophyma (Grades II–IV) generally needs surgery. The review rates the supporting evidence at level III–IV, and prospective comparative studies remain limited.^[7]

Tablets hold the thickening back rather than remove it. The AAD says low-dose doxycycline, a dose too low to act as an antibiotic, can be used long term to prevent further thickening, and that isotretinoin can stop thickened skin from growing thicker but cannot remove what is already there; isotretinoin can cause serious side effects and is not an option for everyone (AAD treatment page). The earlier phyma is treated, the better, because the thicker the skin, the harder treatment becomes. More on these tablets is in rosacea treatment options.

The AAD advises seeing a dermatologist once firm, round bumps or thickening appear on the face, and a rosacea diagnosis visit can then cover any redness and bumps alongside the nose.

Rhinophyma surgery: excision, laser and electrosurgery

For established rhinophyma the review supports partial-thickness sharp excision combined with laser contouring, using CO₂, Er:YAG or newer blue lasers, to improve bleeding control, tissue preservation and the cosmetic result.^[7] The AAD lists surgical removal with a scalpel, laser surgery, radiofrequency and electrosurgery, and advises choosing a dermatologist or dermatologic surgeon experienced in treating thickened rosacea skin (AAD treatment page).

Across the 2,720 pooled patients, scalpel excision (49.0%) and CO₂ laser (37.4%) were the most commonly used treatments.^[5] Electrosurgery applies high-frequency electric current to cut and coagulate tissue. In the 2026 report of two men, one had the thickened tissue removed this way under local anaesthetic, with good control of bleeding.^[6]

Healing after rhinophyma surgery

A wound left this way heals from the gland and follicle remnants in the skin. The case report puts new-skin cover at about 2 to 4 weeks for this technique; its patient went home the same day with advice on gentle face washing, avoiding knocks and sleeping with the head raised.^[3]

The removed tissue goes to the laboratory. The 2026 review calls this histopathological assessment essential because hidden cancers may coexist within rhinophyma tissue,^[7] and the case report names basal cell carcinoma as the most frequent, found incidentally in about 1.4% of one large series and up to 3% in others.^[3]

Thickening can return, particularly after superficial excision, because tissue left deep in the skin can keep growing. Long-term follow-up, sun protection and continued care of the underlying rosacea belong to the plan.^[3]
