Even dermatologist Dr. Kenneth Beer, owner of ScientificSkin.com said: "She has had injections of a filler such as Restylane or Juvederm. To me, it looks like about 1 to 2 syringes of product were used on her upper and lower lips... it will last for about 6 to 8 months."
In photos-taken around the time Lohan's SCRAM bracelet went off at the MTV Movie Awards in June-"her lips look asymmetric, so she was probably having filler even then," points out Dr. Olding.
But he believes she got a touch up before checking into jail because, "There is often an initial period of swelling that occurs with injection that rapidly resolves within the first 24 hours." Dermatologist Dr. Marcy Street added: "Lohan knew the photo of her mugshot would be widely distributed. It is likely she had it done for this reason."
