The Hydrocolloid White Gel Bubble - What Does It Look Like?
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.
Blister!
She got a blister on her big toe that 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 the hydrocolloid 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 white gel 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.
