Is it just us, or islooking a little different these days? Celebrity plastic surgeongiveshis expert opinion on her appearance, after some have speculated she’s had plastic surgery.

It is important to note that Dr. Fisher has NOT treated Lohan. After looking at the most recent pics of the star, especially in contrast to just a few years ago (our before shot above is from 2006), he says it appears she has had some work done.

“She looks like she has had an excessive amount of filler injected in her face,” he says, adding, “I’m not a fan.”

Dermal fillers are non-invasive, non-surgical injections used in the lips, cheeks and under the eye. They can be used to even out scars, as well as in other areas to reshape the surface appearance of the face. Juvederm was a popular filler a few years ago, but many docs have started using Radiesse to enhance shallow contours or soften facial creases and wrinkles because it tends to last longer and have a higher satisfaction rate among patients.
