The Truth: Why Scars Can't "Completely Disappear"

Medically, scars rarely "completely disappear." Every journey leaves traces - any wound reaching the dermis will leave a scar. This is the body's natural healing result, not a limitation of medical technology.

"Our treatment goal is not to make scars 'disappear,' but to make them 'inconspicuous'—color close to skin tone, surface flat, lines extremely fine, so you barely notice them in daily life."

Dr. Ta-Ju Liu

Three Treatment Goals

1

Symptom Relief

Eliminate itching, pain, tightness and other discomfort

2

Appearance Improvement

Make scar color, texture, thickness approach normal skin

3

Function Restoration

Address contracture scars affecting joint movement

Scar Types: Hypertrophic Scar vs Keloid

Correct diagnosis is the first step to effective treatment

Hypertrophic Scar

Hypertrophic Scar

Hypertrophic Scar

  • Scar becomes red, thick, and raised
  • Growth limited to original wound area
  • May be itchy or painful
  • Usually fades naturally over time (months to years)

Treatment: Most can be effectively controlled with intralesional injection; severe cases may consider surgical revision.

Keloid

Keloid

Keloid

  • Grows beyond original wound boundary
  • Continues to grow without regression
  • Noticeable itching and pain
  • Visibly red, swollen, and hard texture
  • Common in certain body types and areas (chest, shoulders, ears)

Treatment: Requires long-term battle with combined therapy (injection + surgery + compression) for effective control.

Atrophic Scar

Atrophic Scar

Atrophic Scar

  • Sunken surface with disrupted skin texture
  • Common after acne, chickenpox, or surgery
  • Subtypes: icepick, boxcar, rolling
  • Subcutaneous fibrosis pulls skin downward

Treatment: Requires subcision + fat/PRP grafting for volume restoration, combined with laser resurfacing for surface texture.

Key Difference: Hypertrophic scars are "self-limiting," keloids "grow beyond the original wound edge."

Three Treatment Approaches

Choose the most suitable treatment based on scar type

Intralesional Injection
First-line Treatment

Intralesional Injection

Direct injection of steroids or anti-metabolic drugs into the scar core to inhibit fibroblast activity, softening and flattening the scar.

  • For: Hypertrophic scars, early keloids
  • Frequency: Monthly, about 3-6 sessions
  • Advantage: Non-invasive, outpatient procedure
Minimal Incision Scar Revision
Precision Reconstruction

Minimal Incision Scar Revision

For old scars or lesions not responding to injection, surgical excision and re-suturing with fine technique to minimize new scarring.

  • For: Mature depressed scars, wide scars, contracture scars
  • Techniques: W-plasty, Z-plasty, flap transfer
  • Advantage: One-time improvement, long-lasting results
Combined Anti-recurrence Therapy
For Keloids

Combined Anti-recurrence Therapy

Combining "core debulking surgery," "post-operative radiation therapy (SRT)" or "long-term local injection," with silicone patch compression—a three-pronged approach to reduce recurrence.

  • For: Stubborn keloids, recurrent lesions
  • Strategy: Multi-directional combined attack
  • Key: Long-term follow-up and compression therapy

The Long-term Battle with Keloids

Not a one-time treatment, but a persistent battle requiring patience

Keloid recurrence rates are indeed higher, depending on body type and wound location (chest and shoulders with high tension are most prone to recurrence). But don't lose hope—

"At Liusmed Clinic, we use 'combined therapy' and emphasize 'long-term post-operative follow-up,' which can significantly reduce recurrence rates. This is a long-term battle, but with persistence, you can see hope."

Dr. Ta-Ju Liu

Liusmed Keloid Control Strategy

Pre-op Assessment

Detailed evaluation of keloid type, tension location, recurrence risk

Core Debulking

Surgical removal of keloid core, preserving edge skin to reduce tension

Post-op Support

Radiation therapy (SRT) or long-term injection to suppress recurrence

Compression Therapy

Silicone patches or pressure garments for 6-12 months

Long-term Follow-up

Regular visits, early detection of recurrence signs for immediate intervention

Frequently Asked Questions (FAQ)

Q1: Can scars completely disappear after treatment?

Medically, it's difficult to "completely disappear." Any injury to the dermis layer will leave a scar. Our treatment goal is to make scars "inconspicuous"—color close to skin tone, surface flat, lines extremely fine—so they're barely noticeable in daily life unless examined closely.

Q2: I have severe keloids—will they recur after treatment?

This is a long-term battle. Keloid recurrence rates are indeed higher, depending on body type and wound location (chest and shoulders with high tension are most prone to recurrence). At Liusmed Clinic, we use "combined therapy" and emphasize "long-term post-operative follow-up" to significantly reduce recurrence rates.

Q3: When is the ideal time to treat C-section scars?

The golden period is 3-6 months after wound healing. This is the scar remodeling phase. We recommend using silicone patches or scar gel as soon as sutures are removed. If you notice the scar becoming red or raised, seek immediate injection treatment for better results.

Q4: Is scar treatment painful?

It depends on the treatment method. Surgery is done under local anesthesia, with substantially less pain. For intralesional injection (scar injections), because scar tissue is hard, you may feel pressure pain when medication is administered. Using our long-developed gentle relief workflow, ultra-fine needles mixed with anesthetic, and no general anesthesia, you can communicate with the physician in real time without general-anesthesia risk; we minimize discomfort, and comfort varies by individual.

Q5: Can old scars (over 10 years) still be treated?

Yes. Although new scars have the highest plasticity, old scars can still be improved through surgical revision (excision and re-suturing) or laser resurfacing. For old white depressed scars, minimal incision scar revision surgery can also be considered.

Q6: How many treatments are needed? What about costs?

It varies by individual. Keloids typically require multiple injections (monthly, about 3-6+ times) to flatten. Scar revision surgery is usually one-time but requires months of post-operative care. Costs depend on scar size, length, and difficulty; actual fees are explained on an individual basis by the doctor during a LINE consultation or in-person visit.

Large-Area Hypertrophic Scars: Why "Completing the Protocol" Decides Flatness

Scars from burns, long surgical wounds, or C-sections are often not a single spot but a long band or an entire sheet. A hypertrophic scar thickens but stays within the original wound boundary — unlike a keloid, which extends beyond the edge and tends to recur. It usually responds better to intralesional injection, and some flatten over time on their own. But to flatten the whole sheet evenly, the entire scar must be injected at many points with even dosing.

The larger the area and the more injection points, the more pain becomes the main reason a protocol is left incomplete — the treated parts flatten while the missed parts stay raised, leaving an uneven result. Letting the whole scar be injected evenly and the full protocol be completed properly is exactly what decides whether it ends up flat.

Gentle Relief, Substantially Less Pain

Our long-developed gentle relief workflow substantially reduces discomfort, with no general anesthesia — so you can communicate with the physician in real time, without general-anesthesia risk, and need not give up over fear of pain, letting the full set of evenly dosed injection points be completed. The method is decided by physician evaluation.

Staged Course, Tracked Adjustment

Honest Disclosure: Effect & Risk

Intralesional corticosteroid (triamcinolone) injection is the main first-line option for hypertrophic scars; it can improve height, redness, firmness and discomfort, but requires a planned course and results vary by individual. Possible risks include skin atrophy/depression, telangiectasia, pigment change, or scar widening; dose and concentration must be judged by the physician, as over-injection may instead cause the original scar to atrophy and sink. Mature, already-flattened old scars usually respond to a limited degree. Suitability and method are determined by the physician in person.

Hypertrophic Scar vs Keloid: Don't Confuse Them

The hypertrophic scar discussed here stays within the original wound, is self-limiting, and usually responds better to injection; a keloid extends beyond the original wound edge, keeps expanding, has a higher recurrence rate, and needs a combined anti-recurrence strategy. The treatment logic differs — if your scar clearly extends beyond the original wound and keeps enlarging, please see the keloid page.
