Celebrities are doing it, your co-workers are doing it, and even your inner circle is doing it. Your besties, however, are loath to admit they’ve had some “work” done. Is your colleague or friend looking a little younger these days? Or is that booty of theirs seeming just a little bit tighter all of a sudden? Trust me, it’s not the Zumba classes, nor is it the juice cleanse they recently powered through. They’ve had something done – a bit of Botox, some liposuction, or maybe a facelift — even if they vehemently deny it. According to Aviva Preminger, MD, a NYC female plastic surgeon, she’s seen it all.
