How Makeup Actually Works

What is actually in a makeup product

Strip any complexion product down and you find the same four parts doing the same four jobs.

• Pigment — the colour. Usually titanium dioxide for opacity plus iron oxides for tone. This is what covers.
• The vehicle — what carries the pigment and lets it spread. Water, silicone or oil. This is the part that decides what your product will get along with.
• Film former — polymers that dry into a flexible skin over the top. This is what makes something long-wear or transfer-resistant.
• Fillers — silica, mica, magnesium carbonate. These control how light behaves on the surface, which is what you experience as finish.

Once you can name those four in a product you are holding, you can predict how it will behave before you put it on anyone.

The single most useful rule: like dissolves like

Water-based and silicone-based products do not mix. Put a water-based foundation over a silicone primer and the foundation will bead up and roll off in little grey worms. That is pilling, and it is not your technique — it is two vehicles refusing each other.

The fix is boringly simple. Match the vehicle. Water over water, silicone over silicone. If you have to cross them, let the first layer dry completely before the second goes on, and press rather than sweep.

Dior Backstage is water-based. That is why it plays well over a hydrating cream and badly over a heavy silicone pore-filler.

Why cream goes before powder, always

Powder works by absorbing the liquid part of whatever is underneath it. Lay powder down first and there is nothing left to absorb the cream you put on top — so the cream sits in a layer, grabs at the powder unevenly, and patches.

Reverse it and everything works. Cream base, cream bronzer, cream blush if you are using one — then powder over all of it, then powder products on top of that.

This one rule fixes patchy bronzer, blotchy blush and streaky contour in a single change.

How finish is actually created

Finish is not a mood, it is optics. Three mechanisms, and knowing which one you are using tells you how it will photograph.

• Matte — light-scattering fillers, usually silica, break up reflection so the surface returns light diffusely. Photographs flat and controlled; on dry skin it emphasises texture.
• Dewy — emollients and reflective micas return light directly. Photographs as health under soft light; under a flash it can read as grease.
• Blurred — spherical particles bend light around texture instead of filling it. This is what Upsalite® does, and it is why a blurring powder does not look chalky the way a traditional mattifier does.

Why setting spray is not a gimmick

A setting spray deposits a very thin polymer film across everything you have built. That film does three things: it binds loose powder so it stops moving, it resists the oil coming up from underneath, and it removes the powdery look by wetting the surface and letting it re-dry as one layer instead of several.

It cannot absorb oil — only powder does that. Which is why the correct sequence is powder first, spray last, and why a spray on its own will not save an oily T-zone.

Undertone, in one paragraph

Depth is how light or dark skin is. Undertone is the colour underneath, and it does not change with a tan. Warm skin has gold or peach beneath; cool has pink or red; neutral sits between; olive has a green-grey cast that most shade ranges handle badly.

A great deal of Moroccan skin is warm or olive. If a foundation that suits your friend turns orange on you, you are almost certainly olive and being sold warm. Neutral shades are usually the answer, and this is the single most common shade-matching error in this market.
