It's not bad as a moisturizer, but I recommend not using it under concealer. It takes a long time to sink into the skin. I only use it at night and had to buy a different type to wear under my makeup, which was a bummer.
This product is OK. It doesn't make the discolouration under my eyes any better or make my bags any worse (Boots Vitamin E eye cream I'm looking at you). It does moisturise the area under my eyes and doesn't upset my skin and is a good under eye base before putting on concealer. But, it's nothing special. On the plus side it is cheap, but I wouldn't repurchase it.
