Do cover scents help with diffusion?

PheromoneXS blends incorporate a proprietary built-in diffusion technology which requires no additional diffusion to assist in lifting off your skin. 

Cover scents simply add a masking scent to the pheromones and while helpful with diffusion, to some extent, they are not necessary as diffusion will still occur. The XS diffusion technology allows you to wear our blends with or without fragrance.
