To maximize the longevity of the fragrance, apply Paul Sebastian Fine Cologne to your major pulse points, such as behind your ears, at the base of your neck, on your wrists, behind your knees, and in the inner elbows. These areas emit heat, enhancing the scent's projection and longevity. A: PS Cologne is designed as an eau de cologne, which offers a moderate concentration of fragrance. While it may not be as potent as an eau de parfum or extrait de parfum, it still provides a pleasant and lasting sillage.
