See What The Hydrocolloid Healing White Gel Bubble Looks Like

by Rebecca Rushton

My mother came to visit last month. She bought a new pair of shoes on her last day, wore them all day, walked all around town and guess what happened.

She got a blister on her big toe! And it deroofed.

Bad news for mum. But as it turned out, good news for me. Because I needed to photograph how a blister heals with a hydrocolloid plaster. There’s only one other photographic example of a hydrocolloid healing showing the white gel bubble and I was keen to enhance that.

The only thing was she was leaving town that day. So she promised she would 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.


How hydrocolloids heal

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
