Customer Reviews (4.5 / 5 · 8 reviews)

James ★★★★★

I was skeptical a primer could pull double duty as a mixing medium, but it blended my thickest foundation into a sheer, dewy finish without pilling. The pearlescent glow is subtle enough for everyday wear, and my skin actually felt more hydrated by the end of the day.

Emma ★★★★★

I was skeptical that a primer could actually hydrate my dry patches, but this serum has a watery, silky texture that sinks right in and leaves my skin feeling plump. It mixes perfectly with my foundation, giving it that subtle pearlescent sheen without looking glittery. Totally worth it for the glow

Eva ★★★★★

That pearlescent glow is no joke—my foundation finally looks lit-from-within instead of flat. The serum texture sinks in fast and my dry patches actually stayed hydrated through a full workday.
