Warm climates include the southern half of the United States and many popular vacation destinations such as the Caribbean islands. Warm climates can be classified as either humid or dry. For example, Florida is warm and humid, whereas Arizona is warm and dry. If you're headed for a warm climate, do some research to determine whether you'll need to pack a drying astringent or a moisturizing cleanser. If it's a warm, humid climate, be prepared to shower a couple times a day and use a cleanser or body scrub that contains salicylic acid [source: Goins]. If it's a warm, dry climate, take shorter, cooler showers and pack baby oil or a petroleum-based moisturizer to apply after showering or bathing [source: American Academy of Dermatology].
The most important thing you can do for your skin in a warm climate -- or any time your skin will be exposed to the sun -- is wear sunscreen with a sun protection factor of at least 15 [source: American Academy of Dermatology]. If you get sunburned, cleanse the area with a mild, moisturizing soap and cool water. Afterward, apply a soothing lotion -- such as aloe vera -- or a topical steroid -- such as hydrocortisone cream -- to the burned area to reduce pain and swelling [source: WebMD].
