Blueberry seeds are a delight to use in soaps. Just a little goes a long way. Melt and pour soap can have speckles throughout with just a small amount of blueberry seed. These are small seeds but still have great exfoliating power. They are a tiny purple addition to scrubs or bath gels Blueberry seeds are a purple hue in color. They are not scented, therefore they do not release a scent.
