True. Rubbing your wrists together after spraying them with perfume will change the way the scent preforms on your skin. The friction you create when rubbing your wrists together crushes the fragrance's molecular structure, causing the top notes fade faster. Although this isn't the end of the world, top notes instantly attract you to a perfume, so it would be a shame to fast-forward your scent experience.
So, the next time you apply your favourite perfume, apply it to both pulse points on your wrist, put the perfume down and walk away!
