Julian Cheung's secret is workouts, but what it is that makes Aimee Chan glow?

When cosmetics brand Clinique invited Canto-pop singer-actor Julian Cheung Chi-lam, 39, to the opening of its concept store in Tsim Sha Tsui's Elements mall, the star revealed the secret of his youthful good looks, endless work-out sessions.

'Of course, I groom, too. But I don't think guys should overdo it,' he said. 'My skin is good because I exercise and I sweat a lot. It's good for detox and gives you better skin.'

The ever-cool Cheung said that when he was not working, he didn't care much about how he looked. Yeah, right!

The other special guest at Friday's event, TVB actress Aimee Chan Yan-mei, was asked more questions about the skin of her rumoured beau, fellow actor Moses Chan Ho, than her own.

'I think he's got perfect skin. I've only touched his face during filming,' she said. 'We have been out for dinner, but friends do go out for dinner. I think we need more time to get to know each other before really getting into a relationship.'

What better way to put a glow on a girl's face than a budding romance?
