Keromask Light Mineral Rich Loose Finishing Powder Keromask Light Mineral Rich Loose Finishing Powder complements all shades of the Keromask Light Camouflage Cream range. Keromask Mineral Rich Loose Finishing Powder sets the foundation, helping to keep it in place & also prepares the skin for additional "dry" products to be applied, e.g. eye shadows & blushers. Once the base is set, any additional products will easily glide on to the skin. Keromask Mineral Rich Loose Finishing Powder also comes in white translucent, medium & dark to ensure a perfect colour match for all skin types.
