Introduction

According to Go to external Internet siterosacea.org:

Rosacea is a chronic skin disorder of the central face (cheeks, nose, chin, forehead) that affects over 16 million Americans.

It presents with flushing, red-faced, acne-like inflammatory bumps and pimples, pustules, or visible blood vessels (telangiectasia or "spider-veins"). The nose may grow swollen and bumpy (rhinophyma). Rosacia may also affect the eyes (ocular rosacea), causing irritation, watering, or bloodshot appearance.

In rare cases, rosacea signs and symptoms may also develop beyond the face, most commonly on the neck, chest, scalp or ears.

This disorder tends to come and go, and tends to progress in severity over time.

The cause of rosacea is unknown [and probably multifactorial]. Although there is no cure, its signs and symptoms can be controlled by [individualized] medical interventions and lifestyle changes.

Please see conventional, complementary, and alternative medical treatments for important background information regarding the different types of medical treatments discussed on this page. Naturopathic, Complementary, and Alternative treatments that may be considered include:


Epidemiology

Rosacea affects about 16 million individuals in the United States. The prevalance in women is greater than in men, but may be more severe in men. The incidence increases with age [Raedler2015  🕮 ].

Ocular rosacea, which affects the eyes, may be a component of about 58% of all cases Go to external Internet siteMedscape

According to Go to external Internet siteMedscape, rosacea is sometimes called the "curse of the Celts" because it most commonly associated with fair haired/skinned people of Celtic descent.


Pathophysiology

Etiology

Although the National Rosacea Society states that the cause of rosacea is unknown Go to external Internet siterosacea.org, there is evidence that the cause may be probably multifactorial. In particular the following possible causes have scientific support:

  • An inflammatory disorder in the context of an altered immune response [Raedler2015  🕮 ].
  • A gastrointestinal infection with Helicobacter pylori Go to external Internet siteMedscape.
  • Psychogenic factors
  • Immunologic reactions to infestation with the mite Demodex folliculorum and Demodex brevis living in facial skin pores Go to external Internet siteMedscape.
  • Microcirculatory disturbances Go to external Internet siteMedscape.

Diagnosis

According to Go to external Internet siterosacea.org:

Rosacea can vary substantially from one individual to another, and in most cases some rather than all of the potential signs and symptoms appear. Diagnosis requires at least one diagnostic sign or two major signs of rosacea [Gallo2018  🕮 ]. Various secondary signs and symptoms may also develop but are not diagnostic.

Diagnostic Signs of Rosacea

The presence of either of these signs is diagnostic of rosacea:

  •     Persistent Facial Redness: may resemble a blush or sunburn that does not go away. [Photo courtesy of National Rosacea Society; click to expand, back to shrink.]
    01b-erythema-rosacea

  •     Skin Thickening: The skin may thicken and enlarge from excess tissue, most commonly on the nose (rhinophyma), which in severe cases can lead to inadequate nasal airflow. [Photo courtesy of National Rosacea Society; click to expand, back to shrink.]

Major Signs of Rosacea

The presence of at least two of these signs is diagnostic of rosacea:

  • Flushing: Frequent blushing or flushing, which may be accompanied by a sense of heat, warmth or burning that comes and goes.
  •     Bumps and Pimples: Small red solid bumps (papules) or pus-filled pimples often develop, but unlike acne, blackheads are absent. [Photo courtesy of National Rosacea Society; click to expand, back to shrink.]
    04a-papulopustular-rosacea-500x500

  • Visible Blood Vessels: prominent and visible small blood vessels called telangiectasia occur on the cheeks, nasal bridge, and other areas of the central face.
  • Eye Irritation: The eyes may be irritated and appear watery or bloodshot (ocular rosacea). The eyelids may become red and swollen, and styes are common. Crusts and scale may accumulate around the eyelids or eyelashes. Severe cases can result in corneal damage and loss of visual acuity.

Secondary Signs and Symptoms

These may appear with one or more of the diagnostic or major signs:

  • Burning, Stinging, Itching, or a Feeling of Tightness: may accompany other signs of rosacea or occur independently.
  • Facial swelling: (Edema) or raised red patches (plaques) may accompany other signs of rosacea or occur independently.
  •     Dryness: The central facial skin may be rough, and appear scaly despite otherwise complaints of oily skin. [Photo courtesy of National Rosacea Society; click to expand, back to shrink.]
    03a-erythema-dryness-rosacea

According to Go to external Internet siteMedscape, in February 2002, the National Rosacea Society further identified several clusters of symptoms that commonly occur together:

Erythematotelangiectatic rosacea (ETR)

The main features of ETR are flushing and [transient] central facial erythema. Secondary features are telangiectasia, stinging, burning, roughness, and scaling.

Papulopustular rosacea (PPR)

The main features of PPR are persistent central facial erythema with sporadic transient papules or pustules. Secondary features may include the features of ETR, but telangiectases may be obscured by persistent facial erythema.

Phymatous rosacea (PR)

The main features of PR are thickened, coarse, irregular skin, enlarged pores, tissue hyperplasia, and nodules. Secondary features may include the features of ETR and PPR.

In partcular, PR that affects the nose is called rhinophyma, which mostly affects men.

Ocular rosacea (OR)

Features of OR include a sensation of a foreign-body in the eye, burning or stinging, dryness, itching, photosensitivity, telangiectases of the conjunctiva, and periocular erythema.

Go to external Internet siteMedscape notes that:

  • Persistent redness of the central face is the most common sign of rosacea;
  • The papules and pustules often appear in clusters;
  • The burning or stinging often occurs upon application of sunscreens, moisturizers, or topical medications;
  • The dry, scaly skin (xerosis) may be itchy.
  • "Peripheral location, including the chest, neck, scalp, or back." Dr. Weyrich notes that other sources stipulate that this is a characteristic of acne vulgare and part of the ddx distinguishing against rosacea.

Differential Diagnosis

The diagnosis of rosacea is based on clinical signs and symptoms, rather than laboratory testing [Raedler2015  🕮 ], Go to external Internet siteMedscape, Go to external Internet siteMedscape. The DDX includes:

  • Rosacea: Does not have comedones; usually affects the central third of the face (rarely other areas of the body); adult onset.
  • Acne vulgaris: has comedones (blackheads or whiteheads), common during adolescense, and can affect back and chest. Absense of deep, diffuse erythema or prominent telangiectases.
  • Seborrheic dermatitis: often yellowish, greasy scale around the ears, eyebrows, and scalp; May involve the nasolabial folds, but not the nose.
  • Perioral dermatitis: most common in young women; no flushing/blushing; may have both eczematous and acneiform features.
  • Carcinoid syndrome: does not have papules or pustules. It is associated with the release of vasoactive mediators from a malignant tumor.
  • Lupus erythematosus: symptoms not limited to facial area; does not have pustules.
  • Demodex folliculitis: caused by mites that can be visualized by microscopic examination and confirmed by therepeutic trial of anti-mite agents.
  • Pityrosporum folliculitis: caused by an overgrowth of the yeast Malassezia that can be visualized by microscopic examination and confirmed by therepeutic trial of topical or oral antifungal agents.

Diagnosis is further confounded by the possible concurrent presence of multiple diagnoses.
