That white gel bubble demonstrates hydrocolloid healing. The weepiness of your blister is combining with the dressing to form a perfect healing environment.
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.
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.

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.
