Choices in nutrition may help slow down the skin’s aging process from the inside, however, it does little to protect from the damaging factors of the outside world. The sun’s harmful UVA and UVB rays cause wrinkles by speeding up the skin’s aging process. This is why it is very important to always wear a sunscreen with SPF 30, or higher, no matter where you live or what the weather is like outside. Smoking speeds up the skin’s aging process as well, also creating wrinkles. It is important that you drink plenty of water in order to keep your skin hydrated, 6 to 8 (8 oz.) glasses daily has been recommended. Vitamins, minerals, and essential fatty-acids help keep the skin healthy and rejuvenated. They can be obtained by eating fresh fruits and vegetables.
