My mother came to visit last month. She bought a new pair of shoes, wore them all day, and came home with a deroofed blister on her big toe. Bad news for mum. But as it turned out, good news for me. Because I wanted to show you the white gel bubble that shows hydrocolloid healing.

There’s only one other good photographic example of hydrocolloid healing showing the white gel bubble and I was keen to enhance that.

The only thing was, she was leaving the next day. So she promised to take photos and send them to me. She did a great job. Her photos clearly show how the hydrocolloid white bubble forms so you can see this is completely normal.

A white gel bubble starts to form within hours which indicates the wound is healing.

What Hydrocolloid Healing Looks Like

Hydrocolloid blister plasters are exudate-absorbent hydrophilic gel dressings. They’re rubbery and slightly translucent. As your deroofed blister weeps, the hydrocolloid material absorbs the fluid and turns into a gel. From the outside, it looks like a white bubble. The dressing remains waterproof the whole time. The white bubble is a sign that your blister is healing.

You can learn more about how hydrocolloid blister plasters work here including:

• When you should change your plaster
• What your blister will look like when you take your plaster off
• Why you should tape the edges of your plaster down

Blister healed! Mum sent me a photo of her healed blister a week later on her way down south.

Here's another example of the white bubble that indicates healing. This one is an actual burn from an oil spill while cooking.
