How to deal with dull and rough skin
Skin dullness and roughness may be caused by aging, sun exposure, nutritional imbalance, iron deficiency anemia, hypothyroidism, and other factors. These conditions can be improved according to individual circumstances. It is recommended to visit a hospital promptly and receive treatment under the guidance of a physician.

1. Aging: With age, the skin's metabolic rate slows down, and thickening of the stratum corneum leads to loss of skin luster, resulting in dull and rough skin. It is recommended to perform gentle exfoliation regularly and use products containing vitamin C, alpha hydroxy acids (AHAs), and other ingredients to help promote skin metabolism.
2. Sun exposure: Long-term exposure to ultraviolet radiation can damage collagen and elastic fibers in the skin, leading to skin aging and possible development of pigmentation spots and sunspots. It is recommended to apply sunscreen, wear sun hats and carry umbrellas when going outdoors; maintain skin cleanliness and use skincare products containing antioxidants.
3. Nutritional imbalance: Poor dietary habits and deficiencies in nutrients such as vitamins and minerals can affect skin health, leading to dull and rough skin. It is recommended to adjust dietary habits to ensure adequate intake of proteins, vitamins, minerals, and water; use skincare products containing antioxidant ingredients such as vitamins C and E.
4. Iron deficiency anemia: Iron is an essential component for hemoglobin synthesis. Iron deficiency can cause the skin to appear pale or dull due to oxygen deprivation and may also be accompanied by symptoms such as fatigue, palpitations, and dizziness. It is recommended to take medications such as compound ferrous sulfate granules, iron dextran tablets, and iron sucrose injections under the guidance of a physician to alleviate symptoms.
5. Hypothyroidism: This condition is usually caused by insufficient secretion of thyroid hormones, which affects skin cell metabolism, leading to rough and dull skin. Symptoms may include fatigue, weight gain, constipation, and dry skin. It is recommended to follow medical advice to take medications such as levothyroxine sodium tablets, Yikang capsules, and thyroid tablets to improve symptoms.
In daily life, maintaining good living habits and a positive mindset can also help improve skin condition.
