Skin flaking is a common phenomenon that affects almost everyone at some point in their life. It can be accompanied by itching, crusting, or skin inflammation. Here are some of the most common causes of skin flaking:

Seborrheic Dermatitis

• Occurs primarily in areas of the skin with many sebaceous glands, such as the face and scalp.
• Characterized by an oily, flaky scalp with mildly inflamed, sharply defined, yellowish-red patches.

Psoriasis

• Affects about 2% of the population.
• Marked by sharply defined, red, sometimes itchy, and raised skin lesions covered with silvery-white scales.

Atopic Dermatitis (Eczema)

• A chronic, relapsing skin inflammation.
• Often begins in early childhood.

Ichthyosis Vulgaris

• A rare hereditary skin disease.
• Patients experience dry skin and increased flaking.
• Scales appear like reptile scales, lying side by side.

Diagnosis

The diagnosis of skin flaking is typically made through:

• Physical Examination: Visual inspection of the skin is often decisive in diagnosis.
• Histology: In some cases, a biopsy may be useful for accurately determining the type of flaking.

Additional diagnostic methods may be used depending on the suspected condition:

• Patch Test: In cases of suspected allergic contact dermatitis.
• Blood Tests: To rule out deficiencies or hormonal disorders.
• Trichogram: When scalp diseases are suspected.

Treatment for skin flaking is based on the underlying cause and may include:

• Use of mild, moisturizing skin care products.
• Topical or systemic medications (e.g., corticosteroids, antifungal agents).
• Avoidance of triggering factors.
• For severe cases: Light therapy or systemic immunosuppressants.
