Load Up On SPF

You know the saying that an ounce of prevention is worth a pound of cure? This = that. Sun is the enemy and is one of the biggest contributors of advanced aging. A daily SPF slows that aging process and will prevent wrinkles from cropping up in the future.
If you avoid sunscreen because you are concerned that it will ruin your tan, stop. Just choose a lower SPF (SPF 20 is a good choice) and make sure that you still apply it to block harmful rays.
