How to treat a Friction Blister

Compeed® active gel cushions contain hydrocolloid, which is designed to create an optimal healing environment that helps wounds heal fast. Compeed® hydrocolloid patches keep the wound moist while protecting the skin against friction and pressure thanks to the cushioning effect, which relieves pain and accelerates wound healing.

The hydrocolloid technology is an active gel containing particles that absorb fluid from the wound. It keeps natural moisture in and dirt out.

There are several types of hydrocolloid bandages that help heal and manage different types of uninfected wounds such as low fluid wounds, spots/pimples, bedsores, superficial burns, leg ulcers, etc.

The Compeed® range of hydrocolloid pads is specifically designed to help heal and relieve blisters and corns. Compeed® active gel cushions should remain in place for several days to optimize the healing process and act like a second skin.

Why does healing in a moist environment accelerate healing?

Healing in a dry environment:

After a wound has occurred, the healing process is immediately initiated: after stopping any bleeding, the blood vessels dilate to release a fluid and cells needed to clean the wound and repair the lesion, thus resulting in a moist environment that is more conducive to the functioning and development of the cells responsible for the healing process. At the end of this phase, the vessels will contract stopping the leakage of liquid or fluid. This will cause the wound to dry out and promote the formation of a thick crust (scab) in order to protect the wound from external infections. In a dry environment, healing must therefore take place under this crust, which slows down the process because the cells involved in the healing process need moisture for their functioning and regeneration. Healing in a dry environment is slow and can be more painful.

Healing in a moist environment:

The hydrocolloid bandage absorbs and retains wound fluid, which keeps the wound moist while protecting it. This moist environment allows “cleansing” cells to move more easily to the wound, reducing local inflammation and promoting the production of collagen, a component of the skin. The cells involved in the healing process therefore develop better in a moist environment. Healing in a moist environment is faster and prevents the formation of a thick crust, thus reducing the risk of scarring.

How does a hydrocolloid patch such as Compeed® act on a blister?

A blister is a type of wound, and the hydrocolloid technology will help it heal faster by keeping natural moisture in and dirt out.

  1. The bandage contains hydrocolloid particles. These hydrocolloid particles are distributed throughout the plaster and absorb fluid from the wound. They maintain an optimal moisture level to accelerate healing. During treatment, the hydrocolloid particles swell, which creates a cushioning effect, redistributing pressure and providing instant pain relief.
  2. The hydrocolloid cushion is composed of a polyurethane film. It is flexible and has a tapered edge that contours smoothly with the skin’s surface. It protects the wound from external bacteria and dirt, thus helping to reduce the risk of infection.
  3. The plaster is form fitting, waterproof and breathable, allowing excess wound liquid to evaporate from the wound while letting the skin breathe.

How to prevent and treat blisters?

Compeed® active gel cushions have a tapered edge to maximize adhesion to the skin. They act like a second skin and remain in place for several days (note: duration may vary depending on the individual).

The hydrocolloid technology in Compeed® products help to protect, prevent and relieve your wound or corn at all stages of development.

  1. Prevention and early signs:

    • Blisters: at the first signs of discomfort, irritation, or blister formation, Compeed® Advanced Blister Care cushions provide instant pain relief by reducing friction, thanks to its cushioning effect.

    • Corns: as soon as a foot corn is emerging, Compeed® Advanced Corn Care pads rehydrate the skin to facilitate the removal of the corn and relieve pressure.

  2. Healing and relief:

    • Blisters: Compeed® Advanced Blister Care cushions relieve the pain caused by blisters and help the skin heal faster.

    • Corns: Compeed® Advanced Corn Care pads relieve pain and maintain a moist environment which helps removing the corn by moisturizing and softening it.
