The Mark Jacobs is available in 30 different shades, and are categorised into four shade families; Light, Medium, Tan and Deep. The lightest shade on offer is Light 110, and the deepest shade on offer is Deep 490.

On the pic, there’s a rundown for each of the shades, which will make it easier for you to find your perfect shade match. It sounds like an amazing concealer/foundation hybrid,
