Fine lines and wrinkles are visible signs of aging that occur as the skin loses elasticity and collagen over time. They often appear around the eyes, mouth, and forehead due to repeated facial expressions, sun exposure, and natural aging. These lines can make skin appear less smooth and youthful. While they are a natural part of the aging process, many individuals seek treatments to soften their appearance and rejuvenate their skin. With the right approach, smoother and firmer skin can be achieved.
