Laura Mercier Flawless Fusion Ultra-Longwear Concealer
by Laura Mercier · makeup
Editor's Take
For long wear, this one earns its keep with Trimethylsiloxysilicate and Boron Nitride, but clean-beauty shoppers should see the silicone load coming.

The Verdict
This is a strong long-wear concealer if performance is the job: Trimethylsiloxysilicate helps it grip, while Boron Nitride and silica soften the look of texture. The trade-off is obvious from the ingredient list, with Cyclopentasiloxane, multiple silicones, acrylates, EDTA, and Phenoxyethanol pulling it far out of clean-beauty territory. The vitamin C derivative is a nice extra, but this is makeup first, not a skin-care concealer. Best judged as a durable, smoothing coverage product with a very conventional synthetic base.
