Take balanced diet and drink plenty of water. The best way to take care of your skin is to protect it from the sun. Ultraviolet rays damages your skin, causing deep wrinkles, dry, rough skin, and liver spots. Select a moisturizer with a sun protection factor (SPF) of at least 15 to help protect your skin from damaging ultraviolet rays. If you spend between one to two hours continuously, then a moisturizer with SPF 30 is what you need.
