It's always been difficult to tackle that final aging issue and still look natural.
But there now is a new filler designed specifically for the lip line.
Phil Glowka says injectable fillers have worked well to smooth some wrinkles and fill hollowness in her cheeks.
Now, she's taking on another trouble spot.
"I have some fine lines in my upper lip and the sides of my mouth that i'd like to see gone," says Glowka.
Plastic surgeon Allan Wulc says lip augmentation can be tricky.
If it's not handled delicately it can can go very wrong, as reality show star Farrah Abraham recently tweeted.
Dr. Wulc says that should happen less with the recently-approved Restylane Silk - a cousin to the popular filler Restylane.
"The lip is something we associate with softness, and so you want a product that feels soft," says Dr. Wulc.
Dr. Wulc says Restylane Silk flows more smoothly.
He even squeezed some out side-by-side with a conventional filler to show the difference in smoothless.
"Because of that smoothness, you can actually use it in the superficial tissues and you don't get lumps," says Dr. Wulc.
Glowka says she got the subtle improvement she wanted.
Dr. Wulc says like other fillers, Restylane Silk lasts about 6 months.
"It feels natural, and looks really good - even in people that have really fine, thin lips," he said.
Restylane Silk also has a numbing agent in it, which should help prevent some of the pain that comes with injecting such a sensitive area.
