Losing weight is not directly linked to reducing crow's feet. Crow's feet are primarily caused by the natural ageing process, where the skin loses elasticity and collagen, leading to fine lines and wrinkles around the eyes. While maintaining a healthy weight can improve overall skin health, it does not specifically target or reduce crow's feet. Instead, treatments like Botox, dermal fillers, and skin resurfacing techniques are more effective in addressing these wrinkles.
