When packing light and hitting the trail, try bringing along a good allover body balm that includes some sun protection. Dermatologists recommend using products with a sun protection factor (SPF) of at least 30 that protects against ultraviolet A (UVA) and ultraviolet B (UVB) rays. There are a number of body balms on the market that have SPFs of 30 or higher [source: ADA]. A body balm with SPF can stand in for sunblock, lip balm and skin and facial moisturizer -- usually in a stick weighing just a few ounces.
You'll also want to bring along talcum powder, which is extremely useful in keeping moist skin dry. Putting talc on areas of your skin where it can chafe, like sweaty areas beneath your underarms where your backpack straps may rub against your skin, can help protect from heat rashes [source: Davidson-Meyn]. Sprinkling talcum powder on your feet and toes absorbs the moisture that can lead to trench foot, a debilitating condition that will knock you off the trail quickly.
Packing light can make any combination product a fantastic idea. This isn't always the case with products that combine sunblock and DEET-based insect repellent. DEET is a chemical ingredient found in many insect repellents. It's designed to evaporate over time -- and to be used in moderation. Frequently applying sunblock with DEET in it could lead to health hazards. When using sunblock and insect repellent separately, apply the sunblock first [source: CDC].
In colder climes, chapping from low temperatures and wind can pose skin problems. Fear not, though: There are products that can be used as both lip balm and a barrier for skin against UV rays and wind. If you're heading out into freezing temperatures, look for skin balms designed for such climates. These products don't have water in their formulas, which ultimately protects against frostbite since the ingredients won't freeze your skin [source: goFASTandLIGHT]. And remember that even though it's cold, the sun continues to threaten your skin. Snow on the ground reflects sunlight well, making backpacking along snowy, sunny areas seem like getting blasted by the sun twice.
Making a few good decisions while backpacking can help you adjust your skin care regimen. Adding just a few extra ounces to your pack can go a long way to keeping your skin safe and healthy -- wherever you take it.
