Mobile phone cases that turn yellow – why?

Mobile phone cases turning yellow – why does it happen and how do you avoid it?

Many people who use transparent phone cases notice that after a while the case starts to take on a yellow tone. This is a common phenomenon and is usually due to how the material reacts with light, heat and natural oils from the skin.

But why do some mobile phone cases turn yellow faster than others – and can it be avoided?

📱 Why do transparent phone cases turn yellow?

Most transparent phone cases are made of TPU or similar plastic materials. Over time, these materials can react to:

• UV light from the sun
• HEAT
• the skin's natural oils
• dirt and dust

As the material changes, it may take on a yellow or darker tone.

Some discoloration can be reduced by cleaning, but if the material has changed chemically, it is often not possible to restore the completely transparent color.

Therefore, many people instead choose mobile phone cases with color or design, as they do not show discoloration in the same way.

There are a few ways to reduce the risk of mobile phone cases turning yellow quickly.

• avoid prolonged exposure to strong sunlight
