Detailed answer

Weight loss or gain can have an impact on the appearance of dark circles and under-eye bags. When a person loses weight, the loss of subcutaneous fat can make the blood vessels under the eyes more noticeable, resulting in the appearance of dark circles. On the other hand, weight gain can cause fluid retention and inflammation, leading to under-eye bags. Additionally, changes in diet, hydration levels, and overall health associated with weight loss or gain can also affect the skin's elasticity and contribute to the formation of dark circles and under-eye bags.
