Acne Rosacea is a chronic disease involving the central face including the cheeks, chin, nose, and central forehead. There are various combinations of flushing, redness, apparent vessels under the skin surface, edema, papules, pustules, ocular changes, and deep inflammation of the nose.
These symptoms may be temporary and each may occur independently. One or more of the features may be present. There are remissions and exacerbations. The causes and mechanism of development are unknown and there are no tissue or serum markers.
Acne Rosacea is common with a prevalence as high as 10% in some populations. It appears to be more common in people with fair skin. Acne Rosacea may occur at any age but most patients are over 30.
Acne Rosacea has been divided into four types. Progression from one subtype to another may occur. It is important to treat Acne Rosacea to prevent development of disease.
what is Rosacea
Rosacea is a common chronic inflammatory disorder of the hair follicles, sebaceous glands and vasculature of the face. The role of Demodex mite in the pathogenesis of Rosacea is controversial.
Rosacea sufferers have recurrent flushing, exacerbated by heat (shower, hot drinks), spicy foods, sunlight, cold, alcohol, and stress. They have sensitive skin, and may complain of dry and gritty eyes.
The peak incidence of Rosacea is 30—50 yr; Females being more affected than Males.
Rosacea sufferers may develop erythema, telangiectases, papules, and pustules of central face; there are no comedones in contrast to acne. Sebaceous hyperplasia, seborrheic dermatitis and facial lymphedema are also more common.
There are 4 Major Subtypes of Rosacea:
Erythematotelangiectatic, papulopustular, ocular, and phymatous.
Chronic inflammation may progress to rhinophyma (enlarged nose; in males). Ocular involvement is also common (e.g., gritty, conjunctival injection, styes, photophobia).
Investigations include clinical diagnosis; uncommonly, skin biopsy is indicated to rule out lupus or sarcoidosis.
Similar conditions that needs to be differentiated from Rosacea are: Acne, lupus erythematosus, perioral dermatitis, sarcoidosis, seborrheic dermatitis.
Treatment of Rosacea is based on severity and subtype.
Lifestyle modification:
Avoid triggers; sun protection and avoidance; facial massage for lymphedema.
Topical antibiotics:
Metronidazole 0.75% gel or 1% cream bid.
Sodium sulfacetamide lotion 10% bid.
Oral antibiotics (moderate to severe cases with inflammatory papulopustular component):
Tetracycline 500 mg po bid
Minocycline 100 mg po od—bid.
Doxycycline 20 mg po bid (subantimicrobial dose therapy) or 100 mg po qd–bid.
Isotretinoin (low dose); less commonly, topical retinoids may be used.
Laser therapy (e.g., PDL, IPL) for telangiectases and ablative laser (e.g., CO2) for rhinophyma.
Camouflage makeup (e.g., Dermablend, Covermark) for erythema.
Ophthalmologist to assess for ocular Rosacea (blepharitis, conjunctivitis, episcleritis).
