Joan Collins has confessed to having Botox but won't do it again because it ''hurts like hell''.

The youthful looking 78-year-old star has finally confessed to trying the wrinkle-smoothing injections in the past but says she would never use it again after having a bad experience.

In an interview with Britain's Glamour magazine, she said: ''I had it once in my forehead and it hurt like hell. Plus you see all these surgical nightmares these days. I have girlfriends who've had Botox and been left with lumps in their faces. And the lips, don't even get me started!''

Instead, Joan relies on make-up, fashion and hard work for her glamorous appearance.

The 'Dynasty' actress is known for her elegant outfits and Joan says it's a constant effort to stay looking good.

She said: ''It's something that takes time and effort. You can't be glamorous if you sling on jeans and a T-shirt with a slogan on it. I strive to be elegant in a time of non elegance. I mean where are all the glamorous women these days?''
