As a sufferer of serious under eye dark circles I have tried so many concealers over the years, but I realised that I was struggling with finding something that helps. Ever since I started wearing makeup, concealer was always the most important product. Yes, mascara accentuates your eyes, and blusher brings colour to your face...but concealer is the product that helps with so many aspects of your look. I have bought cheap products, middle range products and even splashed out on the expensive stuff and I still struggled to get something that covers my dark circles. Whilst at Stansted Airport last year I walked over to the MAC counter to check out the beautiful lipstick range they had and got talking to the lovely beautician at the stand. The Pro Longwear MAC Concealer is £17.50 for 9ml, and although that might seem a lot for a small bottle of concealer, it does last a long time. You only need a little pump of the lightweight fluid to achieve full coverage on your skin and if you apply a few layers onto your dark circles and finish it off with some powder, then you will have a natural looking matte finish. Do you use any of the MAC concealers or do you have a favourite concealer that you would recommend? Let me know!
