Dr Schröder: Perioral dermatitis (POD) 101
What is rosacea? Our founder Kristina has an on/off relationship with rosacea, so we jumped at the chance to get the 101 on this common skin disease affecting girls, boys, women and men of various ages. Here, MD and dermatology specialist Marika Schröder guides us through the what and why of rosacea.
Marika Schröder (MS): Rosacea is more common among women but a lot of men suffer from it as well. It affects only the face, and typically occurs at 30 to 50 years of age. A sudden blotchy facial flush is a typical first symptom of rosacea, which also causes redness, swelling and over time might lead to permanently dilated blood vessels. A rosacea flush usually occurs longer than physiological blushing. Rosacea is not curable, but treatment usually improves symptoms.
Rosacea is divided into four subtypes, and patients may have more than one.
MS: Rosacea is diagnosed based on the patient’s medical history and clinical picture. The symptoms might be only red pimples as in acne. Visible capillaries on the cheeks and/or nose are common but not mandatory, and sometimes also on the forehead. Redness may come and go, often in the form of flushing on cheeks, forehead and nose. Sometimes patients experience strong subjective symptoms such as tightness in the skin as well as a burning sensation.
MS: Rosacea is an internal diseases, with a multitude of underlying causes. It’s often genetic, and a large number of cases might be found in the patient’s immediate family. The root cause for rosacea is unknown, but as said, there may be a genetic component. Hot drinks, alcohol, strong spices, sunlight and sauna may all aggravate flush symptoms. Cortisone ointments for treating e.g. eczema and psoriasis may trigger rosacea-like symptoms on the face. For rosacea, maintenance treatment can prevent exacerbation.
MS: Treatment is chosen according to the patient’s subtype and severity of the disease.
For rosacea, the same oral treatments apply as for acne, i,e, in the case of more severe forms, oral antibiotics, isotretinoin and contraceptive pills are prescribed. Topical treatments differ; topical ivermectin, azelaic acid creams and brimonidine have shown results.
MS: As a general guideline, products which don’t clog pores or irritate skin. For rosacea, it’s also especially important to use sunscreen.
