Seborrheic dermatitis is a skin condition that can cause red, scaly patches to form on the scalp, face, and other oily areas of the body. It's thought to be caused by a combination of genetics and immunology, as well as an overgrowth of a type of yeast that's found naturally on the skin.
There are a number of potential causes of seborrheic dermatitis around the mouth, including:
- Dry skin: This is one of the most common causes of seborrheic dermatitis around the mouth. When the skin is dry, it's more prone to irritation and inflammation.
- Allergies: Allergic reactions can also cause seborrheic dermatitis around the mouth. This is usually due to an allergy to something in skincare products, cosmetics, or even food.
- Sensitivity to weather: Changes in weather can also trigger seborrheic dermatitis around the mouth. For example, cold, dry air in winter can make the condition worse.
