I love the consistency of this concealer, it is really full coverage and I always have a Studio Finish in my collection. This is in NC20 and I get different shades for different times in the year. I like my concealer to be a good coverage and use Studio Finish under my eyes, to cover redness and on any blemishes. It is definitely a good all round concealer and I couldn't be without it. I use it with either my finger or my MAC 224 brush to buff it into the skin. It doesn't crease under my eyes and doesn't get cakey anywhere. I like using it alongside MAC's Studio Fix Fluid foundation.
MAC: A lightweight, creamy, discreetly opaque concealer. Provides a smooth, long-wearing invisible coverage for all skin blemishes. Water-resistant, fragrance-free and non-blemishgenic. This emollient-based, lightweight concealer is so concentrated that a tiny amount can provide opaque coverage of the skin's imperfections and discolourations. It effectively covers dark circles, blemishes, moles, tattoos and birthmarks. Enriched with antioxidants (derivatives of Vitamin A and Vitamin E), it also contains Silica to help adsorb the skin's oils. Concealer has an SPF of 35 and is available in a wide range of colours. It can be applied with a medium to firm fibre brush (try the 242 Brush), a latex sponge, or the fingertips.
