Yes. just make sure the entire wound area and the edges are well covered with MPPT. There is no need to apply excess product as it will only fall off. A few more applications may be needed as the MPPT layer is at risk of being worn away.
Typical situations, where it could be preferable to omit the secondary dressing, are wounds located in a moving or difficult-to-dress area. Another example could be the first 12-24 hours of MPPT use on very highly exuding wounds because for these wounds it is recommended to change the MPPT layer whenever it is soaked which is likely to be two or three times during the first 24 hours. A third example could be in case the skin surrounding the wound is frail and does not easily sustain the adherence of a dressing.
