As a young adult I had very dark marks left behind from acne on my face. This concealer was the only product that actually covered those dark marks.

The only downsides to using this product is that it is so popular that its very difficult to find stock of your shade. And as with most of the more expensive brands, the shades are limited to range between "fair" and "extra deep" so you may not find the perfect match.

In terms of quality, it is a great product. But if you plan on using it every day, I would suggest you check the availability before switching permanently to this brand.
