I bought the powder for the summer, in order to quickly improve the makeup in the T-zone. I did not notice the very small weight, I was concerned about the quality of the product. In this regard I do not have anything to blame for, it does its job, mats for a few hours, gives a light veil on the face, does not settle in wrinkles or pores, no surprises. It also smells lovely. Although the powder come in different shades, it seems to me that it blends into the skin and gives it no color.
If you want to be sure that makeup will stay in place, without unpleasant incidents, Les Voilettes is a great buy. Good durability, good performance.
The only thing that disappointed me is the packaging. Really, Guerlain? Plastic? Yes, it's good quality plastic, powder has fallen a few times and there is no sign of scratches - but for a price it's a bit weak, that the packaging is not in a metal box.
In general, a product worth buying. I checked, I'm happy, as of today, I do not know if I will buy again. There is a lot of other powders to test, and I do not lose my head so quickly for one product.
