I'm looking for a concealer that will cover Melasma. I know certain undertones are supposed to neutralize certain colors. Ive heard Green & Yellow are supposed to counteract red. Lavender supposedly counteracts yellow or sallowness. But the color of melasma is kinda of a light-medium brown color. Every concealer i use to try to cover it, always leaves a grayish look to the area. I know im using the right color for my skintone, cuz the concealer blends into the non-discolored areas of my face, pimples and even my undereye circles which are a reddish-purple tint. And im using KatVon D's Tattoo Concealer, so im not using a wimpy concealer. Any suggestions for a concealer that wont turn my melasma gray. What undertone of concealer should i be looking for? TIA
