Pick up product from both shades with the Secret Camouflage Brush.
Use the back of your Hand as a palette and blend the two colours until you find the right tone. The more you work the product, the easier it will be to apply.
Wipe off any excess product onto a clean part of your Hand so you don't have too much product on the brush. Then apply it to dark areas of the face - pimples, shadows, scars, broken capillaries, around the nose, shadows during the lower lip, or anything else your foundation hasn't managed to cover.
After applying the concealer, gently pat it in with your fingertips to finally set it with Translucent Loose Setting Powder using the Camouflage Powder Brush. The loose powder will ensure your concealer stays put all day.
