concealers can be so hit and miss - they can dry your skin out or be too easily smudged or just look really orange. But I think Bourjois concealer is a really good product. It's mid price range in that if you can't afford to splash out on clinique or something flashy but want a product which actually works and hides dark circles or spots pretty effectively (it's helped me out with both over the years!) As a stick it applies easily and I find that I don't have to keep reapplying throughout the day as you do with some brands thats just rub off, so value for money on that front - it does tend to last well! Also its less messy to apply than say liquid concealers (which also risk leaking!). Finally, it doesn't seem to be bad for the skin wearing it all the time - I've found that some brands can leave areas where you apply it a lot a bit dry/flaky? But not been a problem with this concealer. So a good buy which does the job!
