Welcome to "In Your Face CHAT."   I'm Colin Stewart of the cosmetic-medicine blog "In Your Face."

Our guest today is plastic surgeon

Dr. Val Lambros  of Newport Beach.

Welcome, Dr. Lambros.

I'd like to start our chat with an unplanned topic. It's the breaking news that Johnson & Johnson has pulled its new filler Evolence off the market.

A year ago, Evolence was just reaching the market and was supposed to be strong challenger to Restylane and Juvederm. J&J is huge, so smaller companies such as Irvine-based Allergan, which makes Juvederm, were thought to be vulnerable to a J&J powerful marketing effort.

That never happened.

What have you heard or experienced regarding Evolence?

Let's start our discussion of TV journalist Barbara Walters. She's 80 years old as of Sept. 25, but she doesn't look 80. In part, that's because of a facelift.

What do you see in this post-facelift photo of Barbara Walters?

Readers' comments are welcome.

How would you rate the facelift?

That's rare in Newport Beach, according to your Web site. I take it that you think many of your colleagues in Newport Beach are too quick to turn to the knife when patients come in unhappy with their bodies and thinking they need plastic surgery.

It's time to turn to our next topic – how the passage of time affects the area around people's eyes (and what cosmetic doctors can do about it, if their patients are bothered by the changes).

Here's a pair of photos of a woman at age 21 and again at age 64.

What are the changes that you see?

(Readers' comments are welcome.)

Wrinkles are what strike me first. Are wrinkles typically at the top of patients' lists when they come to you for a consultation when they look like this?

Next, here are photos you sent me of a 42-year-old patient.

On the left (the "before" photo) you said she has high eyebrows and hollowed eye sockets that create a “characteristic ‘concerned’ look.”

On the right, the photo is of the same woman 14 months after injections of filler.

Next, here's a 52-year-old woman who had had upper-eyelid surgery but was unhappy with how she looked.

Shouldn't the facelift and eyelid surgery have taken care of those problems?

We've now come to the end of the time allotted for our chat. Thanks for joining us, Dr. Lambros. I hope we can do this again sometime.

These online chats are scheduled each Wednesday from 12-1 p.m.   Next week's guest (I hope) will be a plastic surgeon with lots to say about male plastic surgery, pec implants, and the use of fillers by male stars such as Brad Pitt. That's still tentative, so watch the "In Your Face" blog for an announcement.

On Nov. 18 our guest will be plastic surgeon Dr. David Shafer, who has developed an iPhone app about plastic surgery.

On Nov. 25, Dr. Christopher Zachary, chairman of the UCI Department of Dermatology, will join us to discuss Zeltiq, a new fat-reduction device that uses cold temperature to break down fat cells.
