This as well applies to sun tanning your skin. Start as soon as possible whenever. Sun tanning purpose is to remove those unsightly tan lines across your shoulder to apply a more evenly color tone on your skin that will give a nice glow to set off your white wedding strapless dresses. Do not apply the toner straight away. Always shower first, exfoliate then apply body lotion to protect the foundation of your skin. Give enough time for the body lotion to completely absorb into the skin then only you start applying the toner. There are different toners for facial as the facial skin structure is different from body skin.
