Speaking to Hello!, Joan said: “I’m very fit and healthy now – knock on wood – and I try to look after myself.”
Having tried Botox once, Joan said it was not for her, and instead she focuses on the very best products, and a full face of makeup.
She continued: “A good base can really help disguise any tell-tale signs of ageing. It’s about base, not Botox!”
“You can tell [I haven’t] because I have lines and jowls. When I see women around my age I think, ‘Oh, really? My gosh, I look quite a bit…’ I think I look pretty good!”
When it comes to her body, Joan is equally careful as she is with her face, and she discussed her workout routine.
The star explained: “Putting on weight – it’s fatal. I have this [indicates lower stomach] and can’t get rid of it. It doesn’t matter what I do.
“I have a trainer who comes over and I do stretches and lunges. We don’t do anything too strenuous because I don’t believe in ‘no pain no gain’.”
The British star’s impressive fortune is thanks to her iconic appearances on TV programmes and films such as Dynasty, The Royals, and American Horror Story.
The actress’ big break came in 1952 when she was given the role of a juvenile delinquent in Believe In You.
In the films that followed, Joan co-starred with big names such as Joan Fontaine, Kenneth More, and Gloria Grahame.
She also appeared in several London plays at this time, including The Skin of Our Teeth and The Seventh Veil. Arguably her biggest role though was as Alexis Colby in Dynasty, which was a global smash TV series, for which she won a Golden Globe.
