From the images I've found I put Nina Hartley in the no box with the Golden Girls cast, while she is definitely smoother she has the deep set mouth-cheek lines I don't care for. Interestingly enough she doesn't seem to have aged much over her career. Julia Roberts is a bad one for me didn't think she was pretty even back when she was young so a solid no. Alura Jenson while smooth is 100% a blow-up doll, seems she's more plastic than woman from what I've found, she even has classic bolt-ons. Couldn't find any images before all the surgeries so in her present state another solid no. Those were some good picks for older yet smooth women when looking only at the skin. I'm very picky with real women, shape and structure are very important to me especially around the face.
