[Rosacea-the updated S2k guideline].

Rosacea is a common chronic inflammatory dermatosis of the face, clinically characterized by erythema, telangiectasia, papules, pustules, and rhinophyma. In January 2022, the updated guideline on rosacea was published. Groundbreaking innovations include the new clinical classification according to phenotypes, extended diagnostic and therapeutic recommendations for ocular rosacea and implications of the gut microbiome on rosacea. Furthermore, the guideline encompasses a new chapter on the psychosocial aspects of rosacea and detailed recommendations for approved and off-label therapies.
