Fine lines are shallow creases that form in the skin over time. They tend to appear first around the eyes, mouth and forehead, and are often one of the first things people notice when they feel their skin is starting to look older than they feel.

They have two main causes. The first is repeated muscle movement — smiling, squinting, frowning — which gradually etches lines into the skin over years. The second is a loss of collagen and elastin as we age, which means the skin becomes thinner and less able to bounce back from that movement. Sun damage, dehydration and lifestyle factors can accelerate both processes.

Because fine lines can be driven by different causes, what works well for one person may not be the right fit for another. That is why we always start with a proper assessment before recommending anything.
