You put on your makeup, check the mirror and everything looks fine. A few hours later, your skin looks completely different. Your face may look oily, dry, dull or patchy. Foundation can settle around your nose, pores can look bigger and your skin may look more textured.
If this keeps happening, adding more makeup usually does not fix it.
The problem can come from your skincare routine, the products you are using, the amount of makeup you apply or simply what happens to your skin during the day.
Here are some common reasons and what you can change.

Your skin may be too oily

Your skin keeps producing oil throughout the day. When that oil mixes with foundation and concealer, your makeup can start looking shiny or uneven.
This is especially common around the forehead, nose and chin.
What to do: Use a lightweight moisturiser before makeup and avoid putting thick layers of product on oily areas. When your face gets shiny, blot the excess oil before adding a little powder.

Your skin may actually be too dry

Dry skin can make makeup look rough and patchy. Foundation may cling to dry areas and make small flakes or lines much easier to see.
Your skin can also feel dry while still producing plenty of oil.
What to do: Use a moisturiser that works for your skin and give it a few minutes to settle before applying foundation. Avoid piling powder over dry areas.

You may be using too many products underneath

Serum, moisturiser, sunscreen, primer and foundation can become a lot of layers.
Some products can also pill when they are used together. You may notice little rolls of product appearing on your skin or your foundation separating.
What to do: Keep your morning routine simple when you are wearing makeup. Give each product enough time to settle before putting the next one on.

Your foundation may not suit your skin

A foundation that works well for someone else may not work well for you.
A very matte formula can make dry skin look rough. A very dewy formula can make oily skin look greasy within a few hours.
What to do: Look at how your skin behaves during the day. If you get oily quickly, a lighter or more oil-controlling formula may work better. If your skin feels tight and dry, a more hydrating formula may look better.

You may be touching your face too much

Hands transfer oil, sweat and dirt to the skin. Rubbing your face can also move makeup around.
You may not even notice how often you touch your forehead, nose or cheeks during the day.
What to do: Try to leave your face alone as much as possible. If you need to fix makeup, use a clean tissue, blotting paper or clean hands instead of repeatedly rubbing the area.

Your makeup tools may need a wash

Makeup brushes and sponges collect foundation, oil and skin cells. If you keep using them without cleaning them, you are putting that buildup back onto your skin.
Dirty tools can also make makeup apply unevenly.
What to do: Clean the tools you use regularly and let them dry properly before using them again.

Heat and humidity can ruin your makeup

Hot or humid weather can make your skin produce more sweat and oil. Makeup can then move around much faster.
This is one reason your makeup may look fine in an air-conditioned room but messy after spending time outside.
What to do: Keep the layers light. Use products that suit your skin in warm weather and blot sweat and oil instead of repeatedly covering them with foundation.

What should you do when your makeup starts looking bad?

Do not immediately add another layer of foundation.
First look at what your skin needs.
If it is oily, blot it. If it is dry, avoid adding more powder. If makeup has separated around your nose or mouth, gently remove the excess before touching up that area.
A small touch-up usually looks better than covering the whole face again.

When should you look beyond your makeup?

If your skin is only looking oily, dry or patchy, the problem may simply be how your makeup is sitting on your skin.
But itching, burning, swelling, redness or a rash is different.
A product may be irritating your skin or causing a reaction. Stop using a product that seems to trigger the problem and speak to a doctor or dermatologist if the reaction is severe or does not settle.

When It May Be More Than a Makeup Problem

If your skin looks worse after wearing makeup all day, you do not necessarily need a new foundation.
Start with the basics. Look at what you are putting under your makeup, how much you are applying, how often you touch your face and whether your skin is oily or dry.
Small changes can make a bigger difference than adding another layer of makeup.
