Wrinkles develop when collagen, elastin, and natural skin moisture gradually decline with age. Environmental factors like sun exposure, pollution, stress, smoking, genetics, repetitive facial expressions, and poor sleep accelerate this breakdown. As the skin becomes thinner and less elastic, fine lines, crow’s feet, forehead creases, under-eye wrinkles, and sagging begin to appear. Timely treatment helps protect skin firmness, texture, and youthful radiance.
