Chemical Subcision For Acne Scars – Release Your Acne Scars From Underneath

Rolling and tethered acne scars are pulled down by bands of scar tissue. Celluject Scar uses a collagenase-led enzyme system to dissolve those bands and let the skin lift — a technique known as chemical, or enzymatic, subcision.

Under-eye filler at Ozhean Zoey
softens bags and dark circles by up to 90% —in a single visit, without surgery.

Why Your Acne Scars Haven’t Budged

Most acne scar treatments work on the surface. Rolling scars are anchored underneath.

Approach

What It Does

The Trade-Off

Creams &
viral skincare

Can improve tone,
hydration and texture at the surface.

Sits on top of the skin. It cannot remove a scar — stop using it and the scar looks the same.

Laser & microneedling RF

Genuinely resurfaces shallow, surface-level scars and refines texture.

Longer downtime, and a real risk of post-inflammatory hyperpigmentation (PIH) if energy runs too high — a particular concern for Asian skin. Makes little impression on deep, tethered scars.

Physical
subcision

Releases the scar from below with a needle — it works.

Painful, heavy bruising, and in inexperienced hands can leave more scarring than it fixes.

Fillers &
biostimulators

Fill the depression from beneath, softening how the scar reads. A PDLLA skin booster is a strong option here.

Genuine but limited — in our clinical experience, filling alone reaches roughly 40% improvement, because the tether pulling the scar down is still there.

Chemical subcision

Celluject Scar

Dissolves the fibrous tethers themselves with collagenase, then triggers fresh, healthy collagen where the scar sat.

No blade, minimal bruising, procedure under 15 minutes. Best for tethered rolling scars; combined with resurfacing and rebuilding for other scar types.

Scars are individual and results vary from person to person. Deep boxcar and ice-pick scars usually need a combined plan — your doctor will map this out at assessment. The 40% figure reflects our own clinical observation, not a published trial.

The Missing Step Most Treatment Providers Look Over

Melt the anchor, then rebuild. That's enzymatic subcision.

A rolling scar is a tug-of-war:
bands of tough scar collagen tether the skin surface downward. Fill on top of it and you're plumping against a rope that's still pulling.

Chemical subcision — also called enzymatic subcision — cuts that rope without cutting the skin. Micro-injections of collagenase dissolve the fibrous band, the skin is free to lift, and the body lays down new, healthy collagen in the space that opens up.

Same release a needle achieves in physical subcision, without the pain, the bruising or the long recovery.

How Does Celluject Scar Work?

How Does
Celluject Scar Work?

Three recombinant enzymes and a healing carrier — each with one job.

Celluject Scar is an enzyme-based system featuring pharmaceutical-grade enzymes produced through genetic engineering for high purity, combined with high-molecular-weight hyaluronic acid.

Collagenase

The scar-release enzyme

The main ingredient. It breaks down the excess scar collagen and the fibrous septa tethering the skin — releasing the depression. Your body then replaces the treated area with new, healthy collagen.

Lyase

The spreader

Loosens the ground substance between cells and improves drainage, so the enzymes disperse evenly across the whole scar rather than staying in one spot.

Lipase

The fat-clearer

Gently reduces fatty tissue bound up around scars — emptying fat cells without destroying them. It isn't hormone-sensitive, so its action stays predictable.

HMW hyaluronic acid

The healing carrier

High-molecular-weight HA creates the environment the other three need to work, and laboratory data links it with a lower fibrosis response as the skin remodels.

The enzymes are produced with recombinant (genetic-engineering) technology to a medical-grade purity by Proteos Biotech — a GMP/GLP-certified maker of sterile injectable medical devices (ISO 13485, Class III).
Higher purity means fewer leftover proteins for the immune system to react to.

The OZ RE:SOLVE Approach

Release · Resurface · Rebuild

One treatment rarely fixes a scar alone. We sequence three moves so each one sets up the next — Celluject Scar is the foundation the rest builds on.

Release

Celluject Scar dissolves the tethers holding rolling scars down (chemical subcision) — so anything we do next isn't fighting a scar that's still anchored.

Resurface

Where scars reach the surface, microneedling RF and laser resurfacing refine texture and even out tone — dosed carefully to protect against pigmentation.

Rebuild

We restore the skin's own structure with the Re20 ECM skin booster and a PDLLA skin booster to fill and firm from within.

What to Expect
From Celluject Scar Treatment?

Typically 2–4 sessions, spaced about 15 days apart, depending on how deep and widespread the scarring is.

Many people notice change roughly 15 days after each session as the release settles and new collagen forms.

Side effects are uncommon and usually mild — some redness, swelling, tenderness or bruising at injection points, easing on their own.

Ideally paired with resurfacing and rebuilding steps for a fuller result — mapped out at your assessment.

Who it isn't for

Pregnancy or breastfeeding.

Active autoimmune disease, or active atopy and asthma.

Allergy to hyaluronic acid or any of the enzymes.

Local or systemic infection, irritated or broken skin.

Active or recent (last 6 months) cancer treatment.

Clotting disorders or ongoing anticoagulant treatment.

Frequently Asked Questions

What is chemical (enzymatic) subcision?

It's a scalpel-free way to release tethered acne scars. Instead of a needle physically cutting the fibrous bands under a scar, micro-injections of collagenase dissolve them chemically — so the skin lifts without the pain, bruising and downtime of traditional physical subcision.

How is Celluject Scar different from a filler?

A filler plumps the dip from below but leaves the tether in place, so the scar is still being pulled down. Celluject Scar removes the anchor first. The two work well together — release with Celluject Scar, then fill and firm with a skin booster.

Which acne scars does it work best on?

It's strongest on rolling and tethered scars — the ones caused by bands pulling the skin down. Boxcar and ice-pick scars usually need a combined plan with resurfacing, which your doctor will design at your assessment.

Is enzymatic subcision painful?

Far more comfortable than physical subcision. It's delivered as tiny micro-injections, the session takes under 15 minutes, and most people have only mild redness afterwards.

How many sessions of Celluject Scar treatment will I need?

Usually 2–4 sessions, spaced around 15 days apart, depending on the depth and spread of your scarring. Many people see a step of improvement about 15 days after each session.

Is there any downtime with Celluject Scar treatment?

Minimal for most. Expect some redness that settles quickly, and occasionally mild swelling or a small bruise at an injection point. There's no open wound and no scalpel.

What are recombinant enzymes and collagenase?

Celluject Scar contains a recombinant enzyme system designed to target excess scar tissue. Its main enzyme, collagenase, helps break down excess collagen within the scar, while lyase and lipase support the overall enzymatic action. It is also combined with high-molecular-weight hyaluronic acid.

Can Celluject Scar help surgical or post-operative scars?

Yes — Celluject Scar is designed for scars and post-surgical fibrosis, not only acne scars. Its anti-fibrotic action targets the same kind of tough, tethering scar tissue. Suitability is confirmed at consultation.

How soon will I see results from Celluject Scar?

Improvement is gradual as the release settles and new collagen forms — often first noticeable around two weeks after a session, building over the course of your plan. Results vary with scar type and skin.

What does chemical subcision cost in Singapore?

Because scars differ so much, we don't publish a fixed price online — the number of sessions and areas drives the cost. Your doctor confirms a clear plan and price at your assessment.
