Dr Stephen Chow, 38, Dermatologist Name three products you can't live without. Moisturiser, cleanser and lotion. What exercise do you do? I go to the gym three times per week. I also go swimming and play golf once every week. What is your best beauty secret? Get exercise, as sweating helps build healthier and more beautiful skin. What is your beauty nightmare? Being overweight or gaining weight. I was very fat in the old days. Have you ever suffered from acne? Seldom, but if I did then I'd use anti-acne cream whenever I got pimples. Do you diet? Never, but I do watch my intake of food. How long does it take you to get ready in the morning? From between 30 minutes to one and a half hours, which includes time for dressing, eating breakfast and reading the morning newspapers. How much do you spend on beauty products each month? None, as I am a dermatologist and I can get all those skincare products from my office.
