Facial redness occurs when the tiniest blood vessels on your face – the capillaries – expand. When they widen, more blood flows through them, which gives the skin a red appearance. Understanding the causes of facial redness can help to reduce its impact: Skincare products – Some products contain ingredients that can deprive skin of its natural oils and cause it to become red and reactive. Opt for mild formulations that are specifically designed for sensitive skin. Sudden temperature changes – These can cause the blood vessels in your skin to expand and flush with blood, leading to redness. Protect your skin by using a broad spectrum sunscreen every day and wear a scarf around the lower part of your face to protect it in cold weather. Spicy food and alcohol – ‘Hot’ spices can trigger irritation, as can too much alcohol. Try to limit your alcohol intake and avoid spices when cooking or eating out.
