Hong Kong dermatologist Dr Louis Shih and optometrist Dr Gary Kots offer some sun safe tips.

Stay in the shade between 11am and 3pm, when the sun's rays are at their most direct and intense.

The best protection against the sun is an umbrella. Dermatologists recommend golf and sports models designed to block  UV radiation.

Wear a hat.  Choose headwear made of close-knit, synthetic material that covers ears and  neck.

Clothes are the best way of protecting the skin, so cover up.

If you're hiking, cover up and make sure you drink lots of water before, during and after the hike.

Any exposed skin should be liberally smeared with sun cream. Reapply  every two hours.

Experts recommend SPF  15 for everyday activities, such as going to the office or shopping, and  SPF 30 to 45 for days spent out  in the sun.

Choose a suncream that gives both UVA and UVB protection. Remember that suncreams only delay the time it takes you to burn. They won't stop it  happening.

If you  get burnt, an ice pack will relieve the pain and aloe vera will assist healing. For serious cases, see a doctor.

Buy sunglasses from a  reputable optician where they can be adjusted to fit,  and buy well-known brand shades.  Ask an optometrist to test lenses with a spectrum analyser.
