Which factors contribute to skin aging?

1. Daily hydration and exposure to sunlight

2. Poor diet and smoking

3. Regular exercise and hydration

4. Consuming antioxidants and sun protection

The correct answer is: Poor diet and smoking

The correct answer focuses on poor diet and smoking as significant factors that contribute to skin aging. A poor diet lacking essential nutrients can deprive the skin of the vitamins and minerals necessary for maintaining its elasticity, hydration, and overall health. Nutritional deficiencies can lead to a breakdown of collagen and elastin, which are crucial for youthful skin. Smoking is another critical contributor; it introduces harmful chemicals into the body, including toxins that can impair blood circulation. This reduced blood flow diminishes the skin's ability to regenerate and repair itself. Additionally, smoking accelerates oxidative stress in the body, leading to premature aging and increased wrinkle formation. Daily hydration and exposure to sunlight can influence skin health, but excessive sun exposure without protection is notably detrimental. While a poor diet and smoking actively weaken the skin's integrity, other lifestyle choices like regular exercise and antioxidants can support skin health rather than contribute to aging.
