Scar Revision
The whole set of procedures used to make an existing scar less noticeable — cutting it out and closing it more neatly, flattening it, releasing it, or resurfacing it. No procedure erases a scar. Revision trades the scar you have for one you would rather live with.
Key facts
Treats
Selected raised, wide or tethered scars
Recovery
Often 1–2 weeks; method-dependent

What is it?
It improves scars.
It aims to improve appearance, comfort or movement.
It uses several methods.
Surgery, injections and resurfacing may be combined.
It does not erase scars.
It modifies scar tissue rather than restoring unscarred skin.
Keloids need special care.
Excision alone can cause a larger recurrence.
What it treats
Scars
Improves width, texture and color.
Keloids
Combined with injections to prevent return.
Acne Scarring
Punch excision for deep scars.
Stretch Marks
Usually treated with lasers or needling.
Treatment areas
Scar Revision
The specific lesion, scar or affected patch determines the treatment site; there is no fixed body distribution.
Scar Revision
The specific lesion, scar or affected patch determines the treatment site; there is no fixed body distribution.
Skin tones
Lighter skin
Low risk
Scar fades over a year.
Medium skin
Some risk
Dark marks possible.
Deeper skin
Higher risk
Keloids can return larger; injections or radiation are often combined.
How it works
Diagram explanation
The scar is assessed: Its shape, location, and tension guide the surgical plan. Tissue is revised or rearranged: A surgeon changes the scar and carefully closes the wound. A new scar matures: Appearance may improve, but scar tissue remains.

Types
Scar revision uses several methods, often combined. The right mix depends on the scar's type, size and color.

Before your treatment
Earlier planning
6 to 12 months: Waiting: Surgeons want 6 to 12 months of natural settling first.
2–4 weeks before
Sun: Keep the scar out of the sun and use SPF 30 or higher.
2 weeks before: Smoking and vaping: Stop both at least two weeks before and after surgery.
Day of treatment
Before you arrive
What to bring: Old photos: Photographs from before the injury, if you have them.
Arrival & prep
The scar is photographed and examined relaxed and stretched.
Treatment
A steroid injection takes minutes and meets real resistance.
Surgical revision cuts the scar out as a narrow ellipse and closes it in layers, usually 30 to 90 minutes. A Z-plasty swaps small flaps to change direction. Punch excision removes a small round scar. Laser or microneedling takes 20 to 45 minutes. Expect pressure, not sharpness.
Before you leave
Tape over the line, wound care instructions, and a date for stitch removal — 5 to 7 days on the face, 10 to 14 days on the body.
After your treatment
First 24 hours
First 2 weeks: Swollen, bruised and tender.
Weeks 2–4
Weeks 2 to 8: The new line turns pink, firm and slightly raised — normal healing, not failure.
Beyond 1 month
Months 3 to 18: Redness fades and the ridge softens from month 3 to 6, with massage and silicone doing the work.
Time to results
Over 6–12 months
How long results last
Permanent
Risks
Risk depends on which procedure is used. An injection and an operation are not the same conversation.
A scar thickening or spreading again
The first sign of a keloid or hypertrophic scar returning. Far easier to treat at 6 weeks than at 6 months.
Itching, burning or tenderness in the scar
Often the earliest sign a raised scar is active again.
A dent or pale patch after an injection
Steroid can thin the fat underneath and lighten the skin. It usually recovers over months, but say so before the next dose so the strength can be adjusted.
A new dark patch
Common on deeper skin tones after any procedure. Treated early, it clears faster.
Numbness or odd sensation
Along the scar, usual for weeks after surgery. Mention it if it is not improving after a few months.
Cost
Typical cost
Varies widely by method
Pricing
In the US this varies more than almost any other dermatology procedure, because "scar revision" covers a five-minute injection and a ninety-minute operation.
Insurance
Insurance often pays when a scar limits movement or vision, interferes with function, or follows cancer surgery or an injury.
Alternatives
Silicone sheets and gel
The best-supported thing you can do at home, and often used alongside everything else. Slow, needs months of daily use, and does nothing for indented scars.
Steroid injection
For keloid and hypertrophic scars. Flattens and stops the itch without surgery. Needs repeating, and can thin the skin or leave a pale patch at the site.
Pulsed dye laser
Targets redness in a scar and may soften a raised one. Little effect on the shape or depth of the scar.
Fractional laser resurfacing
Better on indented and irregular scars than surgery is, with several sessions, real downtime, and more care needed on deeper skin tones.
Microneedling
Cheaper and gentler than laser for shallow texture, with less downtime, but less change per session and no effect on a scar tethered from underneath.
Filler
Immediate lift with almost no downtime, but temporary, and it does not release a tethered scar.
Doing nothing
Reasonable for many scars. Most keep improving for a year or two, and a scar that is settling well may end up better untreated than revised early. Keloids are the exception, because they do not settle on their own.
Silicone gel or sheets
Applied to a fully closed wound most days for 2 to 3 months. The best-supported home treatment for raised and thickened scars, and the sensible default.
Daily sunscreen on the scar
SPF 30 or higher for at least a year. Sun on a new scar is the main reason a line ends up permanently darker than the skin around it.
Paper tape or tension dressings
Tension-relieving dressings, worn over a healing line for weeks to take tension off the closure. Cheap, and worth asking your surgeon whether it suits your scar.
Scar massage
Firm massage of a healed scar for a few minutes daily. Helps soften and flatten, and is the part of home care people abandon first.
Onion extract and cocoa butter
Creams. Popular and harmless, but the effect is small at best. Silicone is the better use of the same money and effort.
Questions
Can a scar be removed completely?
No. Every treatment replaces the scar with a different one — flatter, narrower, paler, or running in a less obvious direction. Often a large improvement, not removal.
How long should I wait before revising a scar?
Usually 6 to 12 months, because most scars keep improving on their own in that time. Scars that limit movement and raised scars still growing are treated sooner.
What is the difference between a keloid and a hypertrophic scar?
A hypertrophic scar is raised but stays within the original wound borders and often flattens over a year or two. A keloid grows beyond them, keeps going, and does not settle by itself. Keloids come back after surgery much more often, so they are usually injected rather than cut.
Will scar revision help my acne scars?
Some of them. Rolling scars respond to subcision, needling and laser; deep icepick scars often need punch excision or a targeted acid technique; boxcar scars sit in between. Expect a course and partial improvement, not one operation.
Does insurance cover it?
Sometimes — when the scar restricts movement or vision, causes symptoms, or follows cancer surgery or trauma. Revision for appearance is cosmetic. Ask the office to check with your insurer before you book.
I have deeper skin tone, and I keloid. Is anything safe?
Yes, but the order changes. Injections, silicone and pressure come first, elective surgery on high-risk sites is approached carefully, and if a keloid is removed, something is always done alongside to control the healing. Tell the provider at the first visit.
