In short. Tethered acne scarring is a depression held down by a fibrous band that pulls the skin toward deeper tissue, often with lost volume beneath it. Subcision divides the band and a filling agent or your own fat lifts the floor, which is why these plans combine steps rather than rely on surface treatment.
Key points
- A rolling scar is often tethered, shallow and sitting over lost volume at the same time.
- Subcision divides the fibrous bands so the surface of the scar can lift.
- Surface resurfacing alone changes the top of the skin and leaves the tether untouched.
- A filling agent is temporary; your own fat may last longer, but not all of it survives.
- These techniques improve appearance; they do not restore the original skin.
What does a tether do to a scar?
When the skin heals after deep inflammation, fibrous tissue can form between the underside of the skin and the deeper layer, pulling the surface downward. The result is a scar that looks shallow when the face is at rest and becomes more obvious when it is stretched, or in low raking light. Some scars do not respond to surface treatment for this reason: the problem is not on the surface. Surface resurfacing alone changes the top of the skin and leaves the tether untouched, which is why results from that approach can be disappointing.
How subcision releases the band
Subcision uses a fine instrument introduced under the skin to divide the fibrous bands, allowing the surface to lift. The procedure is done with local anaesthesia, so it is tolerated rather than felt. Bruising is the expected recovery and it is visible, settling over roughly one to two weeks depending on the area treated.
Refilling a floor that has dropped
Where volume under a scar has been lost, a filling agent or your own fat can lift the floor of the scar. Fat has the advantage of being your own tissue and potentially lasting. It also has an unpredictable component, because not all grafted fat survives. Filling agents are simpler but temporary, and repeat treatment is part of the cost. How long one lasts varies with the product, the site and how the individual breaks it down, and it is never permanent.
| Approach | What it changes | What to plan for | Main limitation |
|---|---|---|---|
| Subcision | Divides the fibrous bands so the surface can lift | Bruising, which is visible and expected | The tether is addressed, the surface is not |
| Filling agent | Lifts the floor where volume under a scar has been lost | Repeat treatment, because it is temporary | Temporary, and never permanent |
| Your own fat | Lifts the floor using your own tissue | An unpredictable component | Not all grafted fat survives |
| Subcision with energy-based treatment or a filler | Addresses the tether and the surface in the same plan | A combined recovery | Still does not restore the original skin |
| Surface resurfacing alone | Changes the top of the skin | Disappointing results where a tether is present | Leaves the tether untouched |
Why are the steps combined?
A tethered scar rarely has one cause. It is usually tethered, shallow and sitting over lost volume at the same time. Treating only one of those leaves the others visible, which is why plans for rolling scarring tend to be combinations rather than single procedures. Releasing the tether and then improving the surface addresses both parts of the problem, and subcision is usually combined with energy-based treatment or a filling agent in the same plan.
What these techniques can and cannot achieve
These techniques improve the appearance of rolling scars and volume-related dents. They do not restore the original skin, and they do not make scarring disappear. For most people the gain is a face that looks smoother in ordinary lighting and in photographs taken at ordinary angles.
When should treatment wait?
Treatment is deferred while the area is inflamed or infected, and it waits until that settles. A bleeding disorder, or medication that affects clotting, changes the risk of bruising and needs to be discussed first. A scar that is raised rather than depressed is treated on a different plan, so it should be assessed rather than treated as a tethered scar.

Frequently asked questions
What does a tethered scar look like?
It often looks shallow when the face is at rest and becomes more obvious when the skin is stretched, or in low raking light. That behaviour is the clue: the surface has been pulled downward from beneath, so treating only the surface changes little. Releasing the band is what allows the scar to lift.
How long does a filling agent last under a scar?
It varies with the product, the site and how the individual breaks it down, and it is never permanent. Repeat treatment is part of the cost of that approach. Fat taken from your own body can last considerably longer, but not all grafted fat survives, so the result is less predictable.
Is subcision painful, and what is the recovery?
It is done with local anaesthesia, so the procedure itself is tolerated rather than felt. The recovery is bruising, which is expected and visible, and which settles over roughly one to two weeks depending on the area treated. It is usually combined with another step in the same plan.
Risks & Limitations
- Scarring is improved, not erased. No treatment restores skin that fibrous tissue has replaced.
- Results take months and several sessions, judged over 6–12 months against standardised photographs.
- Resurfacing carries real downtime and a pigment-change risk that is higher in darker skin tones.
- Treating the surface while acne is still active allows new inflammation to create new scars.
- Unregulated lightening creams can thin the skin and leave pigmentation that is harder to treat.
When to Seek Care
- Acne that is still active and producing new deep, tender lesions — medical control comes first.
- A scar that is raised, firm, painful or still growing after the acne has settled.
- A scar that bleeds, ulcerates or changes shape.
- Skin that is thinning, streaking or breaking out after a lightening cream.
- Scarring with fever, joint pain or weight change, which may point to a systemic cause.
