At 23, Lindsay Lohan should look her best, no matter if she occasionally overdoes it on the self-tanner. Still, deep wrinkles crease her forehead and the spotty skin on her face has something of the quality of parchment, which makes her look 35, beauty experts believe. This is the direct result of many years of smoking, drinking and staying up late at night, leading celebrity surgeon Alex Karidis says, as quoted by SFGate: Daily Dish.

It’s a known fact that bad habits take a toll on one’s countenance, literally adding years to it. Lindsay is a chain-smoker who also loves her drink – or used to, since the last time she went to rehab was reportedly for her alcohol addiction. She is also believed to have dabbled in drugs like cocaine, a report that was never officially confirmed. These and the many nights she spent in clubs instead of getting her beauty sleep seem to have eventually caught up with her.

Recent photos of the actress show her looking worse for wear, as also noted above. Plastic surgeon Alex Karidis, who has not treated Lohan, believes this is nothing but the unsurprising result of so many years of unhealthy habits. “She looks at least ten years older. Those deep creases on her forehead are probably caused by a combination of things, including sun damage, smoking, and too much boozing, which dehydrates and ages the skin.” Karidis explains.

Of course, Lohan is not the only celebrity to take so little care of her appearance, a mistake many young people make simply because they’re young. “When you’re young, you think you’re invincible. But with pale skin like Lindsay’s, it just shows the damage that can be done at such a young age. Skin can deteriorate very quickly. She could reduce the lines by improving her lifestyle, but that would mean giving up the partying.” Karidis further says.

A change in lifestyle could, indeed, improve her appearance, as Kate Moss also learned recently. After seeing photos of herself on vacation in St. Tropez, the model realized that many years of hard partying and overall indifference to what she put in her body (which also included lots of alcohol, nicotine and, as photos have shown, class A drug cocaine) had ruined her face, making her older before her time. Consequently, Moss vouched to ditch her bad habits and focus more on her health, while, at the same time, attempt to regain some of her youthful looks.
