The 45-year-old took to her Facebook page to dispel rumours she's part of the frozen face club - uploading snaps of herself fresh from the shower in unflattering close-up to get her point across.
"Thought about all those damn critics of my face," she wrote alongside the photos.
"Love it or hate it, my face that is, no surgery, no implants, no matter what "they" say. Decided I'd shoot myself to reveal some truths about "beauty" and hope it makes you all easier on yourself.
"Did I every toy with fillers or Botox over the years? Yes. (But) tell me does this look Botoxed to you? Yes I am alone in my bathroom naked in a towel on behalf of women everywhere trying to make a point. Women YOU ARE BEAUTIFUL."
Teri credits good lighting for her glamorous TV image, and says fellow actor Julia Roberts is a great role model for older women, after flaunting a few veins and wrinkles for her latest role in Eat Pray Love.
"Proud of Julia for being a real woman on a real journey," she wrote.
