Rosacea, Redness & Veins

Rosacea's exact cause isn't fully understood, but it's linked to blood vessel abnormalities, an overactive immune response, and genetics. Common triggers include sun exposure, heat, spicy food, alcohol, stress, and certain skincare ingredients, though triggers vary a lot from person to person.

Broken capillaries and persistent redness can also occur without a rosacea diagnosis, often from sun damage, temperature extremes, or naturally thin, fair skin.
