When visiting a tropical island or any location with a tropical or sub-tropical climate for any length of time, it's very likely you will encounter some discomfort because of intense heat and humidity. Sunburn is a common discomfort. Fortunately, suncreen use in the tropics is common and readily available for purchase anywhere. Because there are so many types of sunscreen on the market, it's important to do some research on the best kind of suncreen to buy.

Regardless of the type of suncreen you buy, there are a couple of common sense rules to keep in mind when applying suncreen. If you plan to do a lot of swimming, for example, you will want to keep reapplying sunscreen when you're out of the water since the suncreen you applied earlier washed off. Also, if you will spend time sitting on the beach or by a pool, you should keep reapplying sunscreen every 15 to 20 minutes to protect your skin from harmful rays. Don't assume that applying suncreen once or twice a day will be enough if you're engaging in outdoor activities.

When buying suncreen, it's important to check its sun protection factor (SPF) rating on the label. The SPF rating determines how well it will protect you from sunburn. When buying suncreen, you will want to know if the SPF content in the sunscreen will work for you. Don't assume that a well known brand and high price is what you need. It's more important that what's listed on the label will be effective..

To research the various suncreen products available, use a consumer magazine or website that rates their effectiveness and safety. If you still have concerns and are not sure what to buy, consult your doctor or a dermatologist for their recommendation.
