The only drawback we see with it is that, since it's a powder, it's not great for people with dry skin, especially if you live somewhere with cold weather that exacerbates the problem. Otherwise, the packaging is great, the products (especially the highlighters) are gorgeous, and the formulation is outstanding.
If you're into luxe mineral makeup and skin-friendly ingredients, you might want to put Kide on your radar. The line of baked foundations, concealers, and highlighters, is mica-based, and doesn't contain talc or bismuth oxychloride (the ingredient responsible for the itchiness that sometimes accompanies mineral makeup). Plus, the light reflectors and pigments aren't a bunch of filler metals and lake colors you've never heard of. It's just mica, iron oxide, tourmaline, copper, and diamond dust. The stuff is not cheap at $85 per item, but neither, thankfully, are the ingredients.
