Recommendation to frequency of dressing changes
1. Remove the white and long release paper.
2. Apply the exposed side of the dressing to scar. Ensure the scar is fully covered. Remove the short release paper. Ensure the dressing is fully adhered to scar.
3. Remove the transparent film.
4. Confirm the dressing is fully applied by pressing the boarder of transparent film.

HeraDerm Scar Care Dressing is made of medical pressure –sensitive-adhesive that is comfortable and non-irritant. Scar care dressing is only able to extend along the long side, but not the short side. When applying the dressing on joints, this unidirectional extension design allows patient to move joints freely and produces tension from the short side to suppress scar formation. For longitudinal scars on joints, the unidirection-stretched dressing allows joints to move freely and the non-stretching side suppresses scar formation . The lateral non-flexible design effectively holds and suppresses the scar formation that assists the new tissue growth smoothly and prevents the scar induced.
Scar care dressing adheres to skin tightly to supply sufficient downforce on the scar and decreases the tensile force from a moving joint; the dressing restricts scar projection and extension.

Apply immediately after wound re-epithelialization.
Apply for 8-24 hours daily in the first 6 months.
Apply at least pressure of 21 mmHg to the scar.(average value of the pressure garment)
