Actress Joan Van Ark better face facts – the 71-year-old former 
“Knots Landing” star looks downright scary.

A shocking new photo of Joan – best remembered for her run as Valene Ewing from 1979 to 1993 – reveals she may have gone overboard with cosmetic surgery.

We showed the picture to Dr. Anthony Youn, who has not treated Joan, but is a board-certified plastic surgeon from Michigan.

Comparing the photo to one from her prime, he told The National ENQUIRER: “Her appearance seems to have drastically changed over the years. This may be due 
to quite a bit of plastic surgery.

“I suspect she’s had at least one facelift, if not two, causing her neckline and jawline to look tight. Her forehead is smooth and wrinkle-free, a possible consequence of a brow lift and Botox.”

Dr. Youn added that her smooth facial skin “may be due to multiple chemical peels and laser treatments, along with injections of filler and Botox.

“Overall, I’d recommend she continue taking care of her skin but consider stopping invasive treatments…short of a little Botox here and there if she wanted.”
