Skin aging is caused by several factors:

1. Sun Exposure: UV rays break down collagen and elastin, leading to wrinkles, age spots, and sagging.
2. Collagen and Elastin Loss: As we age, these proteins decrease, causing skin to lose firmness.
3. Slower Skin Cell Turnover: Reduced skin cell production results in dull, thinner skin.
4. Less Hyaluronic Acid: Reduced moisture retention leads to dryness and loss of plumpness.
5. Environmental Factors: Pollution, smoke, and harsh weather damage the skin and cause wrinkles.
6. Lifestyle Choices: Smoking and alcohol dehydrate the skin and reduce elasticity.
7. Hormonal Changes: Hormonal fluctuations, especially during menopause, decrease collagen production.
8. Genetics: Your genes influence how your skin ages.
9. Repetitive Facial Movements: Constant facial expressions create permanent lines.
10. Diet: A poor diet can accelerate wrinkles and sagging.
11. Stress: Increased cortisol levels from stress break down collagen, causing skin damage.
