When using coverage options that have a very high density of coverage you will usually not need traditional color correction. You often see green, red, orange, yellow and even purple based correcting pigments on the market. These are great for neutralizing visible discoloration when paired with regular coverage formulas. With a foundation like Cover Crème, which has 40% high performance pigments, this type of correction isn’t needed. However, depending on the difference in tone from the birthmark and the rest of the complexion it can be helpful to have two shades of foundation or a combination of concealer and foundation that will both neutralize and blend into the overall complexion. If you are covering a birthmark like a port wine stain with a significant amount of red or plum tones the most common mistake is to over correct with green. This eliminates all red tones in the skin (including natural blood flow) and so the area can look flat or lifeless. This is especially apparent in fair to medium skin-tones. It’s much better to correct with a neutral or yellow toned concealer and then follow with your natural foundation match for an overall look that still has the vibrancy of your overall complexion. If you do notice your coverage looking flat, while it may seem counter-intuitive, adding a small amount of pink or red tones to your coverage will bring it back to a more natural tone. If you are covering an area where there is a significant jump in tone it can be helpful to use a second shade to bridge the gap between both tones. This technique is similar to that for balancing vitiligo or scarring with large tonal shifts. For a tan to deep toned complexion with fair to medium tone area its best to balance the complexion by using orange/red toned concealer or foundation over the fair area which adds depth and then overlay a natural foundation match to bring balance to the complexion. This makes it much easier to achieve an even coverage, and also improves how the color correction photographs. For a fair to medium toned complexion with a tan to deep area its best to balance with a peach/orange tone concealer or foundation to neutralize the depth of color before applying a natural foundation match. This will stop the foundation choice looking ashy over the deeper areas.
