There are a few tips and tricks that might increase the longevity of a perfume or cologne scent on your skin throughout the day. First, apply your perfume right after you get out of the shower. You might try moisturizing the areas you are applying to with a moisturizer like Vaseline. Rather than rubbing a fragrance in, try spraying or dabbing in on and letting it dry. Another idea is to spritz your perfume onto your hairbrush and run it through your hair.
