Rosacea: Why does this skin condition affect women more than men?

Approximately 415 million people worldwide are affected by rosacea . This skin condition is characterized by several symptoms, the most common of which is a widespread and diffuse redness on the face, specifically on the forehead, nose, cheeks, and chin, due to the high vascularization of these areas. While rosacea can affect all skin tones, it is particularly noticeable on lighter skin.

Rosacea is a progressive and chronic dermatosis, and tends to operate in cycles. Individuals affected by this dermatological disorder thus see their symptoms manifest for several weeks before disappearing, then reappearing, sometimes more intensely. Over time, rosacea can progress, and, in addition to causing redness, it can lead to the appearance of red pus-filled bumps, a significant thickening of the skin, or even a damage to the eyes.

Research continues to determine the precise causes of this dermatological disorder. However, certain factors have been identified as potential triggers for rosacea flare-ups. These include genetic predisposition, parasitic colonization, heat, sunlight, stress, or certain foods that exacerbate the symptoms of this disease. These various elements, apart from heredity, act by activating nociceptive and inflammatory receptors present in the epidermis.
