What causes skin peeling and flaking?

Skin peeling or flaking may be caused by various factors, primarily including: 1. Dry skin: Prolonged exposure to dry environments or insufficient water intake can cause the skin to become dry and start flaking, sometimes accompanied by itching. 2. Chemical irritation: Using skincare or cleansing products containing irritating ingredients may expose the skin to chemical irritants, leading to peeling and flaking. 3. Poor nutrition: Long-term picky eating or unbalanced diet resulting in inadequate nutrient intake—especially deficiencies in vitamins and proteins—can impair normal skin function and lead to flaking. 4. Skin diseases: Certain dermatological conditions such as eczema and psoriasis can also cause skin flaking, often accompanied by other symptoms like itching and red patches. To address this issue, it is recommended to keep the skin well-moisturized, avoid using irritating products, maintain a balanced diet, and seek medical evaluation and treatment when necessary.
