I suffer from chronic dark undereye circles. Some days these are worse than other days. I have yet to figure out the triggers for the the worse ones. I have tried SO many different concealer/coverup products, ranging from what I consider to be high priced department store products to some of the lower priced items found in discount drug stores. This little twist up tube does one of the better jobs of improving the look of my undereye areas. While it doesn't completely "erase" the discoloration (and nothing I have tried ever has), it does a great job of diminishing it which gives my whole face a much-needed lift. While the name "Line Erase Rx" doesn't suggest that it is a dark circle concealer, that is what I have found it to do the best. And at only about $9 per tube or less if you can find a sale or coupon, I wold highly recommend this product and will continue to use it myself. 0
