Causes

• A dermatologist might diagnose red skin discoloration as a symptom of rosacea, acne, a hormone imbalance, eczema or a variety of different rashes. If the red skin is itchy and/or dry, it could be a seasonal condition (i.e., weather-related).
  
  

Rosacea

• Rosacea, which involves inflammation of the skin on the face, typically affects the cheek area; however, when it carries over to the nose, it is called rhinophyma. Rosacea can be aggravated by certain foods as well as alcohol.
  
  

Acne

• Inflammatory acne can cause red skin since--unlike non-inflammatory which consists of blackheads and and whiteheads--it is characterized by pustules, papules, nodules and cysts. Like the name, inflammatory acne can give the skin an inflamed or red appearance.
  
  

Hormonal Imbalance

• Hormonal imbalances can also be the culprit of red skin discoloration. Hormonal imbalances can cause acne (e.g., think of teenagers) as well as other sort of skin problems. A hormonal imbalance can cause women to grow excessive facial hair, which can cause pore blockage, ingrown hairs and bumps--leading to red skin.
  
  

Eczema

• Eczema is chronic, itchy skin that leads to inflammation of the skin, leaving it red in appearance. Doctors aren't exactly sure what causes eczema, which usually occurs in children and carries on into adulthood, but they believe that it has something to do with the immune system.
  
  

Allergies / Rashes

• Rashes can occur on the skin as a result of an allergic reaction to a variety of different things. Why a rash occurs can be the symptom of a reaction to a pollutant, a household cleaner, a food or medication allergy, plants, pollen or a number of other reasons.
