Buy Guerlain Colognes - Guerlain LHomme Ideal for Men 3.3 oz Eau de Toilette Spray. How-to-Use: *For long-lasting effects fragrance should be applied to the body’s pulse points. *These include the wrist behind the ear crease of your arm and knee and the base of your throat. *Pulse points give off more body heat as this is where blood vessels are closest to the skin therefore continually warming and releasing your fragrance. *Also for a lasting effect spraying fragrance lower on the body allows it to rise throughout the day. *Layering with the corresponding bath or shower gel and lotion also is another good practice to help your fragrance last longer.
