Introducing BlisterPod Hydrocolloid Blister Plasters

I love hydrocolloid blister plasters. They frustrate the hell out of me too! Why? I’ve got 3 problems:

  1. People don’t use them properly
  2. That’s because brands give bad advice on how to use them
  3. They must be sterile to avoid infection and most aren’t

So I’ve sourced, registered and packaged my own Hydrocolloid Blister Plasters (ARTG 306819). And I continue to educate people on how to use them optimally, so their blisters heal as quickly as possible.

Introducing BlisterPod Hydrocolloid Blister Plasters

How they work

Hydrocolloid blister plasters are an exudate-absorbent hydrophilic gel dressing. They have a rubbery texture and are slightly translucent. As your raw blister base weeps, the plaster absorbs this moisture and forms a gel, turning a white colour. This shows that your blister is healing. Contrary to popular belief, this moist environment is the perfect environment for rapid skin healing – strong resilient skin will form instead of a dry, irritating, brittle scab. They ensure your skin heals and returns to full strength faster so you can return to full pain-free activity sooner.

Avoid scabs

Scabs are not healed skin. They are simply a dry lump of wound goo that hides a raw sore underneath. Scabs are easily dislodged and they delay skin healing. Your blister can take twice as long to heal if it scabs over, so don’t leave it “open to the air” to dry out.

One plaster can (and should) last days!

Change your plaster when the white gel reaches an edge of the plaster. At this point, the healing fluid leaks out and infection-causing germs can get in, which you don’t want. Depending on how weepy your blister is, this could take a day or it could take a week. It’s absolutely fine to leave the same plaster on for a whole week. In fact, it’s advisable – as long as it’s not too weepy and the edges haven’t loosened.

Maximum durability

BlisterPod Hydrocolloid Blister Plasters are designed for athletes. They exhibit bevelled edges, good adhesion, a moderate amount of stretch, are 100% waterproof and provide cushioning and protection from further rubbing for up to a week. However, what other hydrocolloid brands won’t tell you is that the edges of any hydrocolloid blister plaster can catch on footwear and stick to socks, even after applying it as best you can. It is advisable to secure the edges of hydrocolloid plasters with a thin flexible tape like Fixomull Stretch. This will ensure a long-lasting seal even in the most extreme endurance athletic situations and challenging environmental conditions.

Don’t make your blister worse

Hydrocolloid blister dressings work their magic on raw weepy wounds only – like ulcers and deroofed blisters.

  • Do not use plasters on intact blisters or torn blisters (see image below). Not only is this a waste of a plaster, you can actually make your blister worse, because when you remove the plaster, it will be stuck to your blister roof and rip it off! Watch the video below.
  • Do not expect hydrocolloid blister plasters to prevent blisters either. In spite of what other hydrocolloid brands recommend, too often this does not work. It’s a waste of a plaster and a misuse of the hydrocolloid material technology. Watch the video below.

A word about Compeed Hydrocolloid Blister Plasters

BlisterPod Hydrocolloid Blister Plasters are sterile and individually packaged. Combined with being waterproof, they are exactly what you need to ensure your blister doesn’t get infected. Do not use unwrapped non-sterile plasters (like Compeed) on your raw weepy blisters. They are not sterile and infection through the broken skin barrier is possible. BlisterPod Hydrocolloid Blister Plasters bring you the convenience of Compeed’s 3 plaster shapes, with the assurance of being free from infection-causing germs.

Sterile, hypoallergenic & latex-free

BlisterPod Hydrocolloid Blister Plasters won’t irritate your skin, no matter how long it stays on for.

Hydrocolloid Blister Plaster FAQ

Q: How do I take my plaster off?

A: Grab one end and pull it parallel with the skin surface – like it’s an elastic band and you’re trying to stretch it out as long as it can get.

how to remove a hydrocolloid blister plaster
To remove, loosen one edge and pull the plaster parallel to the skin surface – like you’re trying to elongate it.

Q: My blister looks infected

A: When you remove your plaster, your blister will look very gooey. And it will smell bad. This is all completely normal. It’s simply the combination of blister plaster and wound fluid. This combination is what helps your skin heal properly. Just wipe the goo off, rinse your blister, apply a bit of antiseptic (eg: Betadine) and put a new plaster on once the surrounding skin is dry.

Q: How will I know if my blister really is infected?

A: The white gel will be more yellow or green in colour (ie: pus). And your blister may be red around the edges. If this is the case, apply antiseptic and use island dressings instead of hydrocolloids for a few days until the pus goes away. If it doesn’t appear to be getting better, seek medical advice. And if you see red streaks extending from your blister up your foot or leg, you need medical attention to fight that infection, probably in the form of oral antibiotics (tablets).

Q: How will I know if my blister is too weepy?

A: If you’re having to change your plaster every 24 hours or less, it’s too weepy to benefit from the healing powers of a hydrocolloid. If you notice a lot of white wrinkly macerated skin around your blister when the plaster comes off, it’s too weepy. It could be excessively weepy if your blister is very large and deep. It can be too weepy if you haven’t removed the blister-causing irritant (let’s say you continue to wear the same pair of shoes that are too tight).

Another reason I see at 6-day ultramarathon races is the pounding of the activity continues due to the fact it is an endurance race. In these situations, it’s better to use island dressings, changing them frequently (at least twice per day), until the blister-causing factor is negated or the blister starts to weep less. At this point, you can speed things up and benefit from the way hydrocolloids work.

Q: Is this product registered with the Australian Therapeutic Goods Administration (TGA)?

A: Yes it is. Our Australian Register of Therapeutic Goods (ARTG) number is 306819. It is also FDA cleared and has CE certification. Here’s the material safety data sheet.
