Scientific advances in the production of make-up

Why milling matters

A blush is only as good as its grind. Modern air-jet mills get pigment down to a few microns, which is why today’s powders melt instead of sitting.

What that means on deep skin

Fine pigment disperses evenly instead of pooling light or dark. Two swirls of a brush give a wash; four give a full cheek.

How we test

Every Ìrì shade is worn for a full Lagos day — danfo, sun, office air-conditioning — before it makes the compact.

The takeaway

Good makeup is engineering you cannot see. If it looks effortless at 8pm, the science did its job.
