What Loreal promises with the carbon black:
2 X the intensity
Similar to the others in the voluminous range the carbon black brush is small but mighty! Filled with tiny bristles that separate your lashes and coat them with fibers to give them length. The carbon did deliver in separation and length but lacked in volume and drama. WIth the title carbon black I expected an intense black effect but found it no darker than the original in the voluminous range with similar effect of natural volume. Testing it out in humid weather it did start smudging by the afternoon.
