Skin redness is a widespread problem and can have many causes. One of the most common causes is a reaction to external factors such as cold, heat, cosmetic treatments, cleaning products, or food. This reaction can lead to skin irritation, which manifests as redness, itching, and/or pimples. Another cause of skin redness is excessive sun exposure, which leads to sunburn. Redness without an identifiable trigger, especially when combined with symptoms like itching or burning, may indicate a skin condition. Below is a summary of the most common causes of persistent redness and how to support your skin with proper care.
Sensitive skin
Signs
- Diffuse red patches on the skin
- The facial skin feels tight
- Redness is associated with a burning and heat sensation.
- Persistent itching
- Skin prone to intolerances or allergies
The reason sensitive skin is prone to irritation is a compromised skin barrier. This barrier is the skin's natural defense mechanism, designed to protect it from external influences. Triggers for a weakened barrier can vary. Genetic factors and psychological stress can make the skin more vulnerable. Stress can even lead to rashes. Other contributing factors include hormonal changes, improper skincare, over-treating the skin, and environmental stressors (UV radiation and urban pollution).
Proper care: Use special products for sensitive skin; it is important to strengthen the skin barrier and reduce redness.
Avoid: Products containing alcohol, scrubs with abrasive particles, strong heat or cold, UV rays
Couperose
Signs
- Red veins are visible on the cheeks and nose.
- Extensive skin reddening on the face, neck and décolleté
- The complexion appears uneven and restless.
- The skin is prone to irritation.
- Often in combination with dry skin
Visible veins and red cheeks become more common on the face from the age of 30 onwards. This is due to a hereditary weakness of the connective tissue. The redness often occurs on fair, pale, and sensitive facial skin. As with many skin problems, lifestyle can negatively affect the complexion and exacerbate dilated blood vessels and redness. Those with couperose should avoid spicy food, regular sauna visits, and excessive consumption of alcohol, tobacco, and coffee.
Tip: Redness can be well covered with a green primer or camouflage makeup and provides a good base for makeup.
Proper care: Special products that stabilize and soothe the skin, improve the elasticity of dilated blood vessels and support connective tissue.
Couperose can also develop into the chronic inflammatory skin disease rosacea. This must be diagnosed and treated by a dermatologist.
