How Mixing Two Products Changes Your Makeup Finish

Common Mixes and What They Do

Our guide on what makes makeup high coverage explains why adding non-pigmented products makes foundation sheerer: the same pigment is spread over more product.

Wear time changes too. Moisturisers, oils and many illuminators contain ingredients that stay slightly slippery on the skin, which can soften the film that holds foundation in place. That is why dewy mixes often look beautiful in the morning but need a touch-up sooner than foundation used on its own.

Why Matching Bases Matters

Makeup and skincare are built on different bases: some are mainly water, some are mainly silicone, some are oil-based. Products with similar bases tend to blend smoothly together. Products with very different bases can separate, bead up or pill.

A quick way to tell is to read the first few ingredients. If both start with water, they usually mix well. If one starts with water and the other with a silicone such as dimethicone or cyclopentasiloxane, they may still work, but test first.

Mix a small amount on the back of your hand. If the mixture looks smooth and even, it is likely to wear well. If it separates, looks curdled or beads up, it will probably pill or separate on your face.

Our guide on how to stop skincare pilling explains why some combinations roll up on the skin.

Temperature and time also matter. A mix that looks fine when first combined may separate if left for several minutes, so apply it promptly. Warming the mix slightly between your fingers can help it spread more evenly.

How to Mix Makeup Products for a Custom Finish

1. Choose compatible products

   Pick products with similar bases where possible.

2. Use a clean surface

   Mix on the back of your hand, a clean palette or a mixing plate.

3. Start with foundation

   Dispense your usual amount of foundation first.

4. Add the second product gradually

   Add a small amount, mix, and check before adding more.

5. Apply as usual

   Use a damp sponge, brush or fingers to press the mix into the skin.

6. Check in daylight

   Look at the finish and colour after a few minutes.

7. Mix fresh each time

   Do not store mixed products; make only what you need.

Mixes to Avoid

Sunscreen and makeup. Mixing sunscreen into foundation or moisturiser dilutes it, so you get less protection than the label states. Apply sunscreen as its own layer, in a generous amount, and let it set before any makeup goes on top. Active treatments and makeup. Adding retinoids, exfoliating acids or vitamin C to foundation can change how both products perform and may cause irritation. Large batches in the bottle. Pouring a second product into your foundation bottle can upset the formula’s preservative balance and stability, and you cannot undo it if you dislike the result. Very different bases. Heavy oil with a long-wear water-in-silicone foundation, for example, often separates.

Getting Sun Protection Right When You Mix

If you enjoy mixing your base, keep sunscreen separate. Apply it as the last step of your skincare, let it set for a few minutes, then apply your custom foundation mix on top.

The AAD’s guide on how to apply sunscreen recommends using enough to cover all exposed skin and reapplying when outdoors, which is only possible if sunscreen is applied on its own.

Our guide to physical versus chemical SPF in cosmetics explains why SPF in makeup is best treated as a bonus rather than your main protection. The same applies to a foundation mix: whatever SPF the foundation carries is diluted further once you add another product.

Mixing Shades for a Better Match

Mixing two foundation shades is one of the most useful tricks for getting a perfect match, especially between seasons when your skin tone shifts.

Mixing works best with two shades from the same foundation range, since they share the same base and finish. Mixing across brands can work but is more likely to separate or change finish. If you do mix across brands, check that both have a similar texture and finish, and test on your jaw before committing to a full face.

If your undertone falls between two options, mixing a warmer and a cooler shade of the same depth can also help. Our guide on how foundation shades are formulated explains why undertone matters so much.

Choosing Mixes by Skin Type

Dry skin: adding a drop of moisturiser or liquid illuminator can make foundation more comfortable and less likely to cling to dry patches. Oily skin: avoid adding oils or rich moisturisers. A mattifying primer mixed into foundation, or applied underneath, usually works better and helps the base last through the day. Combination skin: you can use two mixes: a dewier mix on the cheeks and a more matte one on the T-zone. Mature skin: sheerer, dewier mixes often look more natural and settle less into fine lines than heavy full-coverage foundation. A drop of liquid illuminator mixed into foundation, applied only to the high points of the face, can add life without emphasising texture.

Mixing Concealer, Blush and Other Products

The same principles apply beyond foundation. Mixing a little concealer into foundation gives more coverage without a separate step, which is useful for covering redness across the cheeks.

Cream or liquid blush can be mixed with a drop of foundation to create a sheer, natural flush that blends seamlessly. Liquid highlighters can be mixed into moisturiser for an all-over glow on bare skin days.

Lip products can also be mixed. A little balm softens a matte liquid lipstick, although it will reduce its long-wear properties.

In each case, start with a small amount of the second product and build up gradually. It is easy to go too far and end up with something too sheer, too shiny or the wrong shade. Mixing on the back of your hand lets you check the colour against your skin before it goes on your face.

Hygiene and Storage When Mixing

Mixing on a clean surface keeps bacteria out of your products. The back of a clean hand works for a single use; a metal palette is easier to wipe clean and does not absorb product.

Clean your palette, spatula and sponges regularly. A damp sponge that sits in a warm bathroom is a good environment for microbes, so wash it often and let it dry fully.

Do not store a mixed product for later. Mixing can change how well the preservatives work, and a custom blend left in an open container can spoil. Make what you need, use it and clean up.

Our guide on why stability testing matters explains why products are tested as finished formulas rather than mixes.

Dos and Don’ts

Honest Limits

Mixing changes a formula that has been designed and tested as a single product. Wear time, finish and even colour can change in ways that are hard to predict.

Not every mix works for everyone. A combination that looks beautiful on one person may separate on another because of differences in skin type, skincare and climate. Treat online mixing tips as ideas to test rather than guaranteed results.

If you find yourself always mixing to fix a foundation, it may be worth trying a formula that gives you the finish you want on its own. Tinted moisturisers, skin tints and satin-finish foundations already offer many of the effects people try to create by mixing.

When to See a Dermatologist

• You break out after starting a new makeup mix.
• Your skin becomes red, itchy or irritated after applying makeup.
• You have persistent dry or flaky patches that makeup clings to.
• You are unsure whether a reaction is to makeup or skincare.

FAQ

Summing Up

Mixing two products changes the balance of pigment, oils, water and film formers, which is why it can make foundation sheerer, dewier, more matte or a better colour match.

Mix small amounts fresh each time, choose products with similar bases, test the mix on your hand and keep sunscreen as its own layer. If a mix separates or shortens wear too much, adjust the ratio or switch products.
