Laura Mercier Real Flawless Weightless Perfecting Foundation — 0C1 Opal.

Real Flawless Weightless Perfecting Foundation is a weightless, long-wearing formula that blurs the line between makeup and skin. It delivers medium, buildable coverage with up to 12 hours of waterproof, fade-proof wear and lifts sallowness and dullness for a healthy, colour‑true finish. To use: apply one pump to clean skin with a foundation brush and layer over your preferred primer for best results.
