Wrinkles form through a combination of factors: the skin naturally produces less collagen and elastin as we age, which reduces its firmness and bounce. Repeated facial movements, such as smiling or frowning, can etch creases over time, especially in areas like the forehead and around the eyes. Sun exposure and environmental damage accelerate this process. Different wrinkles respond to different approaches, so a qualified provider can assess your specific concerns and discuss which options may suit you.
