MAC Zoom Fast Black Mascara is probably one of my favorite items of makeup which I've ever bought! I always used to use regular Zoom Lash which is also great, but Fast Black is the blackest of black carbon mascaras and is so effective! On a number of occasions whilst wearing it I've been asked a) if I've got false lashes on b) if I've had lash extensions and c) which mascara I use! It lengthens and thickens ones lashes and makes them stand out! It's great because one can build with it and reapply over it again and again to achieve as thick/long lashes as one wants! It's also so dramatic, because it's such a deep, rich black! It truly is the best mascara I've ever worn! It's also really good value for money - only R145 and lasts around 3 months! Only downside is the removal - because of its intense black pigment, it takes a little longer to take off, but it's SO worth it!
