ABSTRACT

Acne rosacea is an inflammatory skin disease with a multifactorial etiology. The characteristics of the disease include hyperreactivity of the blood vessels, mediated by the nervous system. Erythema and telangiectasias develop under the influence of several factors. In the course of acne rosacea there occur papules, pustules, and nodules. Dietary acne triggers include products associated with heat, alcohol, capsaicin, and cinnamaldehyde. In addition, researchers demonstrated an association between UV radiation and rosacea exacerbation. Opinions on the effects of alcohol and nicotine on rosacea remain divided, and further research is needed. Studies suggest an association between obesity and rosacea; in addition, patients with rosacea often have coexisting risk factors for cardiovascular disease. Numerous studies emphasize the influence of external factors such as diet, UV radiation, alcohol, and smoking on the course and pathophysiology of rosacea. The multifactorial etiology includes neurovascular dysregulation, impaired immune response, and dysregulation of the skin microbiome. Various food substances can regulate rosacea's course by activating the relevant receptors.
