2. MAC Studio Finish Concealer SPF 35
Virtually invisible coverage and available in 15 shades, this long-lasting, water resistant and lightweight concealer is so concentrated you just need a teeny tiny dot to cover imperfections, so should last about 6 months. Silica helps absorb the skin's oils to keep you matte all day (it worked wonders on my shiny t-zone) and the high pigment means it can even cover moles, birthmarks and tattoos.
