Clarins Instant Concealer (£21/ shade 01/ 15ml)

"Fatigue fighting, smoothing and long wearing concealer. Want refreshed radiant eyes all day? Instant concealer provides customised correction for all types of dark circles. It is tinted to mask the colour of dark circles while restoring the skins natural tone. It's fluid texture blends flawlessly. This skin smoothing formula visibly conceals dark circles for a brighter, even and refreshed look throughout the day. Medium to full coverage."

So this concealer comes in a small tube which is great for controlling how much product comes out, the only flaw is that it's not clear so you can't see how much is left. This is a very creamy, moisturising concealer but it's dries fast so blending needs to be done quite quickly. I would say that this is definitely more on the full coverage side but of course it can be sheered out depending on taste. Although the this is designed solely for dark circles and does seem to contain reflective properties I actually find it works really well on blemishes. I found this didn't work too well with a brush and definitely applied better with fingertips or a beauty sponge. This concealer doesn't seem to crease badly and the 'long wearing' claim rings true, I would say the only major downfall is that there are only 3 shades in the range. 

I highly recommend this concealer if you can find a shade to match your skin, it's worth the high price tag in my opinion, the coverage is almost comparable to that of MAC Pro Longwear. A potential holy grail right here.
