The fragility of blood vessels is linked to their increased permeability, which allows various inflammatory factors to penetrate the skin. This results in a diffuse redness often accompanied by a burning sensation. Vascular skin refers to facial skin that tends to redden easily and is highly reactive to external and internal stimuli.
Couperose skin is considered extremely sensitive. Redness frequently appears around the cheeks, nose, and chin, and can be aggravated by triggers, e.g., coffee, strong tea, alcohol, hot spices, and even hot meals. Redness can also appear when the ambient temperature changes, or when you are emotional or nervous.
Dilated capillaries can occur in any skin type, but the most susceptible to this condition is delicate, thin, and sensitive skin. The depth of the skin’s vascularization is also important.
