Fine lines and wrinkles are common signs of aging that appear on the skin as small creases or folds, typically around areas like the eyes, mouth, and forehead. They occur as a result of the natural decline in collagen and elastin production, which are essential for maintaining skin’s firmness and elasticity. Factors such as sun exposure, environmental pollution, smoking, and repetitive facial expressions can accelerate the formation of these lines. While fine lines tend to be shallow, wrinkles deepen over time. Regular skincare that includes anti-aging ingredients like retinoids, peptides, and antioxidants can help reduce their appearance and maintain smoother, more youthful-looking skin.
