Princess Perfume (プリンセスパフューム Purinsesu Pafu~yūmu) are the main transformation devices in this season. In order to transform, the Cures also need a Dress Up Key, which they insert into the top and turn to fill the bottom with perfume of their theme colour, which they spray during the transformation.
- These are the third perfumes used as transformation items, after Heart Perfumes and the Shiny Perfume from the season Heartcatch Pretty Cure!.
- The Princess Perfume is so far the sixth transformation device to appear as a cosmetic item, after the Milky Palette (Yes! Pretty Cure 5 GoGo!), Heart Perfume (Heartcatch Pretty Cure!), Smile Pact (Smile Pretty Cure!), Love Eyes Palette (Doki Doki! Pretty Cure), and PreChanMirror (Happiness Charge Pretty Cure!).
