Start small.
When trying a Lily Essences scent for the first time, apply one light pass on a small area and make sure your skin is comfortable with it.
After that, application becomes personal.
One pass is generally more than enough for normal fragrance wear. Someone who prefers a much more noticeable scent may choose two or three passes.
More is not automatically better.
Apply the amount that gives you the fragrance presence you enjoy.
A thin layer of petroleum jelly underneath can also help the scent stay noticeable longer, and giving the oil a minute or two to settle before clothing touches the area is a good habit.
