The wound-contact layer and secondary dressing system

Short answer

Separate Lunwell’s antimicrobial role at the wound bed from the exudate-management role of the secondary dressing and understand each layer of the dressing system.

Published / updated: 11.08.2026

A modern dressing system does not require one material to perform every function. Wound contact, exudate management and fixation can be resolved in separate layers. Lunwell is the antimicrobial layer placed directly at the wound bed.

Layer 1 — The wound bed

The dressing system is planned according to tissue depth, infection status, exudate and anatomical location. Debridement, infection control and management of the underlying cause cannot be separated from the selection of a wound-contact product.

Layer 2 — The Lunwell antimicrobial contact surface

The porous polyester mesh conforms to the wound bed. Silver-coated fibres contact wound fluid, make Ag⁺ ions bioavailable and establish an antimicrobial barrier at the surface. The non-adherent structure positions Lunwell as the contact layer.

Layer 3 — The secondary absorbent dressing

Lunwell does not absorb exudate. Its open mesh allows fluid to pass into the secondary dressing above it. The absorbency of that secondary layer is selected according to wound exudate and performs the fluid-management function of the system.

Layer 4 — Fixation

Lunwell is non-adhesive. The contact and secondary layers are held in place with a bandage or fixation method suited to the anatomical area and clinical need. Fixation should maintain secure contact without unnecessarily restricting circulation or movement.

  • Lunwell provides antimicrobial wound contact.
  • The secondary dressing manages exudate.
  • The fixation layer keeps the system in place.
  • Change timing follows the condition of the wound and secondary dressing.
  • Lunwell’s antimicrobial barrier window is seven days.

Two common points of confusion

  1. Porous does not mean absorbent. The pores transfer exudate into the secondary layer; they do not store fluid inside Lunwell.
  2. A seven-day barrier does not mean every dressing must remain unchanged for seven days. Exudate, wound appearance and clinical monitoring may require an earlier change.
