Hypafix is a dressing retention tape, and the manufacturer sells it for holding dressings and devices on the skin rather than for treating scars. Silicone gel and silicone sheeting remain the first-line option that scar guidelines recommend. Hypafix still has a role in scar care, holding a silicone sheet or a dressing in place, but it is not a substitute for one.
People ask this because Hypafix looks the part. It is soft, breathable, skin-coloured under clothing, and it stays on for days, which is roughly what a scar tape does.
The mechanism behind scar therapy explains why the resemblance only goes so far.

What is Hypafix designed to do?
Hold a dressing, a tube or an appliance against the skin over a wide area.
The manufacturer describes Hypafix as wide area fixation. It is a non-woven fabric tape with a low-allergy polyacrylate adhesive, permeable to air and water vapour so the skin underneath can breathe, and chemically inert to rubber and plastics. You cut what you need from a gridded roll.
Nothing in that description is a scar claim. Breathability and long wear make it a good fixation tape, and neither property treats scar tissue.
A tape that stays on for four days is a good retention tape. Staying on is not the same as changing how a scar matures.
What does the evidence say works on scars?
Silicone leads. Silicone gel sheeting and silicone gel have been used on scars for more than 30 years and sit at the top of scar management guidance for raised, hypertrophic and keloid scars.
The mechanism matters here, because it explains the tape question. Reviews of the research point to occlusion and hydration doing the work, rather than anything unique to the silicone molecule. Cover a healing scar, keep the surface hydrated, and the scar behaves better. The Textbook on Scar Management chapter on silicone gel notes that other semi-occlusive materials, including paper tape and polyurethane film, have shown effects through the same route.
Taping has its own small evidence base. Tension across a healing incision drives hypertrophic scarring, and studies of paper tape applied across a closed surgical wound, including a trial in women after caesarean section, found less hypertrophic scarring where the tape offloaded that tension.
| Option | What it does | Evidence position |
|---|---|---|
| Silicone gel sheet or gel | Occludes and hydrates the scar surface | First line in scar guidance |
| Paper or microporous tape across an incision | Reduces tension across the healing line | Supportive, mostly in surgical scars |
| Hypafix | Holds a dressing or a silicone sheet in place | No scar claim from the manufacturer |
| Massage and moisturiser | Softens and hydrates | Common clinical advice, modest evidence |
| Pressure therapy | Applies sustained pressure to raised scars | Used in burns care under specialist supervision |
Does Hypafix have any role in scar care?
Yes, as the thing that holds the treatment on.
Silicone sheets lose grip as their tack picks up skin oils, and they slide under clothing or during sleep. A strip of fixation tape over the top keeps the sheet where the surgeon put it. Hypafix is well suited to that job because it is wide, breathable, and cuts to any shape.
- Holding a silicone sheet: cut a piece an inch larger than the sheet on all sides and round the corners.
- Securing a post-surgical dressing: the standard use, and the reason most people have a roll at home.
- Protecting a fresh scar from clothing friction: a covered scar rubs less against a waistband or a seatbelt.
What it will not do is replace silicone or flatten a raised scar on its own.

Is it safe to put tape on a scar?
On a closed, fully healed incision, taping is common practice and generally well tolerated. Three conditions decide whether it is a good idea for you.
- The wound has to be closed. No open areas, no scabbing that lifts, no drainage. Tape over an open wound traps moisture against tissue that needs a proper dressing.
- Your surgeon or nurse should agree with the plan. Scar protocols vary by procedure, and some teams start silicone at two weeks while others wait longer.
- Your skin has to tolerate it. Fresh scars sit on skin that has been through surgery, tape and antiseptic. Watch the first few days for redness that persists after the tape comes off.
Sun protection does more for scar appearance than most people expect. New scar tissue pigments easily, so keep it covered or use sunscreen once the wound is closed.
Stop and ask your clinician if the scar becomes itchy and raised beyond its original border, which can point to a keloid rather than an ordinary scar.
What should you use instead?
For scar therapy itself, ask your surgical team about silicone gel or silicone sheeting, which we do not stock. For everything around it, ordinary fixation supplies do the job.
- To hold a silicone sheet or a dressing: Hypafix, cut to shape.
- Over a joint or a moving area: Cover-Roll Stretch, which flexes with the skin.
- On fragile or reactive skin: reduce how often you change the tape and remove it slowly, since the removal does more damage than the adhesive.
Cover-Roll Stretch, an elastic non-woven tape that follows a shoulder, knee or abdomen as it moves, so the edge lifts less on a scar that crosses a joint.

Frequently asked questions
Is Hypafix a scar tape?
No. Hypafix is a dressing retention tape for holding dressings and devices on the skin. The manufacturer makes no scar treatment claim for it, and scar guidance points to silicone gel or sheeting as the first-line option.
Can I use Hypafix instead of silicone scar sheets?
It is not an equivalent. Silicone sheeting works by occluding and hydrating the scar, and it has decades of clinical use behind it. Hypafix can hold a silicone sheet in place, which is a supporting role rather than a replacement.
Does taping a scar help it heal flatter?
There is some evidence that tape across a closed surgical incision reduces hypertrophic scarring by offloading tension on the healing line. That research used paper or microporous tape rather than Hypafix, and it applies to fresh surgical scars, not old ones.
When can I start putting anything on a new scar?
Once the wound is fully closed with no scabbing or drainage, and after your surgical team says it is time. Many teams start scar management around two to three weeks after surgery, though this varies by procedure.
Will Hypafix irritate a healing scar?
It uses a low-allergy adhesive and is well tolerated by most people, but skin around a fresh scar is already stressed. Remove the tape slowly and low to the skin, and give the area a break if redness lingers after removal.
