What is Skin Redness?

Redness is a persistent or recurrent skin concern presenting as dilated or dysfunctional superficial blood vessels, commonly affecting the face, neck, and sun-exposed areas. Causes range from UV exposure, genetics, and natural ageing to hormonal fluctuations, skin trauma, and environmental and lifestyle triggers. Common forms include diffuse redness, visibly dilated capillaries, post-injury redness, and rosacea.

Rosacea Subtypes

Rosacea subtypes diagram
  • UV radiation – UVA and UVB progressively damage superficial vessels, causing visible dilation and dysfunction over time.
  • Genetics – certain genes determine how strongly the immune system and vessels respond to triggers, driving chronic inflammation and persistent redness in predisposed individuals.
  • Natural Ageing – vessel walls thin and lose elasticity with age, becoming permanently dilated and visible beneath the skin.
  • Hormones – fluctuations during menopause, pregnancy, or from certain medications disrupt vascular control, increasing sensitivity and flushing.
  • Skin Trauma – prolonged inflammation from acne, picking, or burns triggers localised immune dysregulation, disrupting vessel healing and causing persistent redness.
  • Environmental & Lifestyle Triggers – temperature extremes, alcohol, stress, and certain skincare products overstimulate superficial vessels, particularly in predisposed skin.
