This is my go-to tinted moisturizer. The coverage is light but it layers very nicely. In the summertime, sometimes I layer it and add some translucent powder instead of doing full foundation. In the winter, it's a nice little protective layer from the cold dry elements. I have really sensitive skin and this is also one of the only moisturizers that doesn't irritate my skin or clog pores. Basically it is amazing, everyone loves it, and I highly recommend it.
This tinted moisturizer is by far the best I have ever tried and I have tried many. Everything from BB Creme (MAC, Maybelline, Garnier) and Tinted Moisturizers (St. Laurent, Nars) and you cannot beat the Mercier for the perfect coverage and lightness. A little goes a long way and hides imperfections while making the skin look flawless and natural. I use the regular but sometimes add in a little of the Illuminating for a little highlighting at night. There are so many different shades that will work for any skintone. Give it a go. You won't be disappointed.
