General UseIDUN Minerals Powder/Large Kabuki BrushIDUN Minerals brushes are made of taklon - the finest quality of synthetic whose properties are similar to natural bristles but without the disadvantages that natural hair can bring. Taklon brushes do not shed hair or irritate the skin like natural brushes can. Unlike natural bristles, which can have an irregular surface where dirt and bacteria easily accumulate, taklon bristles are smooth. They are non-allergenic and very easy to clean. This brush is suitable for both IDUN MINERALS Foundation and IDUN MINERALS Powder. UseIDUN MINERALS products are massaged into the skin and applied to a fine, even finish. With a sufficiently hard pressure on the skin with the brush, the minerals melt in and settle like a thin fine veil over the skin. They are neither seen nor felt. The result is a fresh and natural complexion.
