Good concealer for covering up blemishes on the skin, not so much for the undereyes. I have this in 3 - Warm Medium and it matches me well (NC35). I have to say that the dryness and opacity of this concealer is exactly what I want on top of blemishes, but because of those same exact qualities, it makes my undereyes look a bit too dry for my taste. The product lasts reasonably well on top of my oily skin and reminds me of Charlotte Tilbury's Magic Away Concealer in terms of longevity and coverage.
It's quite inexpensive at £4.19, widely available in Boots, and is travel/purse friendly for those times when you need a little touch up for first dates or impromptu after work drinks. It's definitely not the best concealer in the world but it really does the job well. Highly recommended for beginners venturing into makeup; it's really easy to use with a doefoot applicator + fingers, and it vanishes those pesky blemishes away.
If you can't find your shade at this time (October 2019), the Collection website is offering two shades for the price of £6 which is a pretty good deal if you ask me.
