Fine lines and wrinkles are visible signs of aging that develop as the skin loses its natural elasticity and firmness. Typically forming around the eyes, mouth, and forehead, they are caused by repetitive facial expressions, decreased collagen production, and exposure to environmental stressors. While these lines are a normal part of the aging process, they tend to deepen with time, gradually diminishing the skin’s smooth, youthful look. Proper skincare and targeted treatments can help reduce their appearance and support skin health.
