When Catherine Zeta Jones stepped out last week with her husband, Michael Douglas, it wasn’t Mr. Douglas’s good health that was causing whispers amongst guests and journalists. Catherine appeared to be sporting a rather youthful appearance for her 42 years. An appearance many have attributed to a visit to a cosmetic doctor.

As a known smoker, Catherine Zeta Jones is one of many women who have suffer the side affects of smoking. Smoking causes skin to dramatically age, so it was particularly surprising to see Catherine with a flawless complexion. The Welsh film star looked healthy and line free when she appeared alongside her husband at the 2012 Windward School benefit at Cipriani 42nd Street in New York City.

Celebrity plastic surgeon Dr. Anthony Youn, spoke to Radar.com about Catherine’s new look. He said, “Catherine Zeta-Jones looks like she’s beginning to follow in her husband Michael Douglas’ plastic surgery footsteps,”

“Her cheeks look somewhat plump, and may be due to injections of a filler like Sculptra. Her forehead and crows feet are also very smooth for a woman her age, likely a result of Botox injections,” he explained.

The smoothness of her cheeks makes Catherine look young and healthy, and while she is both, the healthy skin tone of her cheeks may have been supplemented with a small amount of filler. This helps explain the lack of lines around her mouth as well as the firmness of her lower face.

Dr. Youn explained, “Botox is typically not injected under the eyes, though, hence the wrinkles in her lower eyelids,”

It’s not safe to use Botox below the eyes, so there are still fine lines and wrinkles there, but the tops and outer edges of the eye are smooth and healthy looking. Catherine is a perfect example of how a combination of Botox and fillers can help keep the face young with minimal intervention.

Catherine and her family have been under significant stress since husband Michael was diagnosed with throat cancer in August 2012. It is therefore understandable that given the recent stress and persistent press scrutiny, Catherine may have needed some help from non-surgical treatments. She has however, managed to strike a balance between preserving her natural beauty and stalling the sands of time.
