Mac Cosmetic Pigments are jars of colorful loose powder. The price seems a bit high, but I have had a jar of Vanilla pigment for more than a year and it still looks like I haven't even touched it. It's a color I use almost daily. The color spectrum is broad for pigments and Mac is notorious for bringing out new, limited edition pigments all the time. I have found unlimited uses for pigment. It can be combined with clear nail polish for nails, clear gloss for lips, highlighting the cheeks, blush, applied with a mixing medium as eyeliner, eyeshadow, etc. There is absolutely no scent in these pigments. The only downfall for this product is that it can be messy since it is loose powder. I personally would not let that stop me from trying these beautiful colors. It's the most highly used beauty product I own.
