The B. Flawless Concealer Duo is designed to counteract dullness and minimise the signs of fatigue, such as under-eye circles, as well as to conceal skin imperfections. The two shades can be combined for a bespoke finish. Blend the creamy formulas directly onto the skin to find the perfect colour match for your skin tone. The formula is lightweight and will give you an even complexion, leaving your skin with a fresh and flawless look all day long.
