What causes rough skin on the chest area?

Rough skin on the chest area may be caused by multiple factors: 1. Dryness is one of the main causes. Especially when the air humidity is low or irritating cleansing products are used frequently, the skin tends to lose moisture and oils, becoming dry and rough. 2. Prolonged exposure to sunlight without sun protection can damage the skin with ultraviolet radiation, causing it to become rough. 3. Poor nutrition and deficiencies in vitamins and minerals may also affect skin health, leading to roughness. Additionally, certain skin conditions such as eczema and psoriasis can also make the skin rough. To improve rough chest skin, it is recommended to keep the skin moisturized by using hydrating products; avoid prolonged sun exposure and take proper sun protection measures; and maintain a balanced diet to ensure sufficient nutrient intake. If symptoms persist or worsen, prompt medical attention is advised.
