I use the Collection Lasting Perfection Ultimate Wear concealer in the shade 1 Fair on my spots, redness and acne scars. I have used it for about two years now and nothing quite conceals those horrendous flaws like this little beauty does. It's a little orangey like the Rimmel wake me up concealer, it's not as dark but it's the closest shade to my skin tone. This concealer blends in like a dream and it has incredibly high coverage- it covers every single imperfection possible without looking cakey, unless you were to apply it onto broken skin. As you can see in the photos the writing on the packaging has rubbed off which I hate but Collection has now upgraded their packaging.
You can purchase the Rimmel Wake Me Up Concealer here from Boots for £5.49 and the Collection Lasting Perfection concealer here from Boots for £4.19
Have you tried any of these concealers?
