The 'Dad's Army' star admits she struggles to keep her skin feeling hydrated because of her constant travelling and has likened it to a crisp.

Speaking in a webchat, she said: "I'm finding, just from travelling from New York and being in heated hotel rooms, my skin feels like a Walker's crisp at the moment, but I've been using some argan oil just to saturate my skin at night, so it has some nourishment as I sleep, to start the day a little bit more hydrated.

"The real hydration comes from within. You can never drink too much water. No diet sodas! I think happiness is the best tonic for keeping us youthful. Being happy with who you are inside radiates on the outside."

Meanwhile, the 46-year-old actress previously insisted she is not "aesthetically beautiful".

She said: "I am not aesthetically beautiful. I have a broken nose, I had a tracheotomy when I was a kid, I have broken capillaries and I'm always asking my husband, 'Do I look fat in this dress? Can you see that spot on my face?'"
