Fine lines and wrinkles form as collagen and elastin levels decline, reducing the skin’s ability to stay firm and smooth. Over time, repetitive facial expressions, sun exposure, and environmental stressors contribute to creases and folds on the skin. While fine lines are superficial and often appear first, deeper wrinkles develop as skin loses elasticity. By restoring hydration, stimulating collagen, and relaxing facial muscles, modern aesthetic treatments can smooth wrinkles and refresh the skin’s appearance.
