For those living in the UK, you can try the following:
Concealer brush: A proper one will help give a really soft edge to the concealer, making it less visible once you apply foundation. Try Revlon's Concealer Brush with high grade fibres (available from Superdrug).
Foundation brush: Applying with this will give a more even finish than using your fingers. Try Vie At Home Deluxe Foundation Brush(available from
vieathome.co.uk).
Powder brush: Applying with a big fluffy brush will set your foundation and give a flawless finish. Load with either pressed or loose powder, tap off any excess and apply with sweeping movements. Try Famous By Sue Moxley Powder Brush, which has a mixture of real and synthetic bristles (available from Superdrug) or Clinique Powder Brush made from natural hair (available nationwide).
Blusher brush: You only need one brush with a big head. If you choose one with tapered bristles, you can use it to shade and contour your cheeks. Try the hard-wearing Autograph Blusher Brush, a mixture of real and synthetic bristles (available from Marks & Spencer).
Eye shadow brush: As long as the brush isn't too big, you can use one eye shadow brush to apply colour all over the eye. Build the colour up slowly rather than slicking lots on straight away which can then be hard to blend. Try The Body Shop Nature's Mineral Eye Shadow Brush which is 100 per cent synthetic (available from The Body Shop).
Eyeliner brush: There is no room for error when applying your eyeliner so you need a really fine, stiff brush to give precise results. I love Bourjois Eyeliner Brush which has angled bristles for applying shadow really close to the lash line (available from Boots, Superdrug, Tesco, Debenhams).
Lip liner brush: Another fine brush is needed for this, but your lip liner brush can also be used to apply the colour to your lips. Try No 7 Essential Lip Brush which has a blunt tip to help define the edges of your lips (available from Boots).
