What diseases cause dry flaky skin on face?

Several skin conditions and diseases can cause dry, flaky skin on the face. Here are some common ones:

1. **Eczema (Dermatitis):** Eczema is a chronic skin condition characterized by inflammation, redness, and itching. It can lead to dry, flaky skin, and there are different types of eczema, including atopic dermatitis and contact dermatitis.

2. **Psoriasis:** Psoriasis is an autoimmune condition that accelerates the skin cell turnover rate, resulting in the rapid buildup of cells on the skin's surface. This can lead to red, scaly patches.

3. **Seborrheic Dermatitis:** This condition often affects areas rich in oil glands, such as the face and scalp. It can cause redness, flakiness, and greasy scales, commonly referred to as dandruff when it occurs on the scalp.

4. **Rosacea:** Rosacea is a chronic skin disorder that primarily affects the face, causing redness, flushing, and sometimes, pimple-like bumps. Dry, flaky skin can be a symptom, particularly in the later stages.

5. **Contact Dermatitis:** This condition occurs when the skin comes into contact with an irritant or allergen, leading to inflammation and a rash. It can cause dryness and flakiness on the face.

6. **Tinea (Ringworm):** Tinea is a fungal infection that can affect the skin, including the face. It often presents as a red, circular rash with a raised, scaly border.

7. **Hormonal Changes:** Changes in hormone levels, such as those occurring during puberty, pregnancy, or menopause, can impact the skin's moisture balance, leading to dryness and flakiness.

8. **Autoimmune Diseases:** Certain autoimmune diseases, like lupus, can affect the skin, causing dryness, redness, and rashes on the face.

9. **Ichthyosis:** This is a genetic disorder that results in the skin becoming dry, thick, and scaly. It can affect various parts of the body, including the face.

10. **Malnutrition:** A deficiency in essential nutrients, particularly vitamins and minerals, can lead to dry, flaky skin.

11. **Allergies:** Allergic reactions to certain foods, medications, or skincare products can manifest as skin dryness, redness, and flakiness.

If you are experiencing persistent or severe symptoms of dry, flaky skin on your face, it's essential to consult with a dermatologist or healthcare professional for an accurate diagnosis and appropriate treatment. They can help identify the underlying cause and recommend a suitable course of action based on your specific condition.
