The actual perfume elements and extracts in oil fragrances are far more concentrated than those in standard alcohol-based perfumes, which contain only a small amount of true fragrance diluted with alcohol and other fillers.
Apply your perfume to these points — namely, the inner wrists, the base of the throat, behind ear lobes, in the cleavage, behind knees, and the inner elbows. These spots emanate heat, which can help fragrance to emanate from your skin into the air. (It's the same principle used by essential oil diffusers).
Please Note: Perfume oils smell drastically different in the vials than they do on the skin. We recommend applying a little to your inner wrist and letting it dry down some to get the best idea of how the scent truly smells on you. Perfume oils will smell slightly different from person to person due to their unique body chemistry.
