Acne scars can remain long after active acne has healed, affecting skin texture and self-confidence. While creams and topical treatments may improve skin quality, they often have limited benefits for deep, depressed scars. One of the most effective minimally invasive procedures for treating these scars is subcision.
Subcision is a dermatological procedure that releases the fibrous bands pulling the skin downward, allowing the depressed scar to elevate naturally. It also stimulates collagen production, leading to gradual improvement in skin texture over the following months.
At Collagen Clinics, Jaipur, subcision is commonly performed as part of a personalized acne scar treatment plan. Depending on the type and severity of scars, it may be combined with microneedling, platelet-rich plasma (PRP), laser resurfacing, chemical peels, or dermal fillers to achieve optimal results.
This comprehensive guide explains how subcision works, who can benefit from it, the procedure, recovery, possible risks, and expected outcomes.
What Is Subcision?
Subcision, also known as subcutaneous incisionless surgery, is a minor dermatological procedure used primarily to treat depressed acne scars and certain other types of tethered scars.
During the procedure, a specially designed needle or cannula is inserted beneath the scar. The dermatologist gently releases the fibrous bands that tether the scar to the deeper tissues. Once these bands are released, the skin gradually lifts, and the body’s natural healing response stimulates new collagen formation.
Unlike treatments that work only on the surface of the skin, subcision targets the deeper structural cause of many depressed scars.
How Does Subcision Work?
Many depressed acne scars develop because fibrous connective tissue pulls the skin downward.
Subcision works through two important mechanisms:
Release of Fibrous Bands
The needle carefully breaks the fibrous attachments beneath the scar.
This allows the depressed skin to elevate naturally.
Collagen Stimulation
The controlled healing response stimulates collagen remodeling.
New collagen gradually fills the treated area over the following weeks and months, resulting in smoother skin texture.
Which Types of Acne Scars Can Subcision Treat?
Subcision is most effective for tethered atrophic scars.
Rolling Scars
Rolling scars have:
- Broad depressions
- Sloping edges
- Undulating skin surface
These scars respond particularly well because they are usually caused by fibrous tethering beneath the skin.
Boxcar Scars
Some boxcar scars, especially those with soft edges, may also improve with subcision.
Deeper or sharply defined boxcar scars often require combination treatment.
Mixed Acne Scars
Many patients have a combination of:
- Rolling scars
- Boxcar scars
- Ice-pick scars
In these cases, subcision is often combined with other procedures to address each scar type appropriately.
Which Scars Do Not Respond Well to Subcision?
Subcision is generally less effective for:
- Ice-pick scars
- Raised (hypertrophic) scars
- Keloids
- Active acne lesions
- Deep surgical scars without tethering
Your dermatologist will examine your skin carefully to determine whether subcision is suitable.
Who Is a Good Candidate for Subcision?
Subcision may be appropriate for patients who have:
- Rolling acne scars
- Tethered scars
- Stable acne
- Realistic expectations
- Good general health
It can be performed in both men and women with appropriate skin evaluation.
Who Should Avoid Subcision?
Subcision may not be recommended for individuals with:
- Active acne flare-ups
- Active skin infections
- Bleeding disorders
- Uncontrolled diabetes
- Certain blood-thinning medications
- Active herpes infection in the treatment area
- Severe keloid tendency (depending on clinical assessment)
A thorough consultation helps determine whether the procedure is suitable.
Common Conditions Treated with Subcision
Although subcision is best known for acne scars, dermatologists may also use it for selected cases of:
- Traumatic scars
- Surgical scars
- Chickenpox scars
- Cellulite (selected cases)
- Certain depressed scars following injury
The suitability of subcision depends on the type of scar and clinical evaluation.
Benefits of Subcision
Subcision offers several advantages when performed for appropriate indications.
Targets the Root Cause
Instead of treating only the skin surface, subcision releases the deeper fibrous attachments responsible for depressed scars.
Stimulates Natural Collagen Production
The body’s healing response gradually produces new collagen, leading to continued improvement over several months.
Minimally Invasive
Subcision is performed through a small needle entry point without large surgical incisions.
Suitable for Most Skin Types
Unlike some resurfacing procedures, subcision can often be performed safely in a wide range of skin types when appropriate techniques are used.
Can Be Combined with Other Treatments
Subcision works well with several other acne scar treatments, allowing dermatologists to develop individualized treatment plans.
Consultation Before Subcision
Every patient should undergo a detailed consultation before treatment.
Your dermatologist will assess:
- Type of acne scars
- Duration of scars
- Previous treatments
- Active acne
- Skin type
- Medical history
- Current medications
- Healing tendency
Clinical photographs may be taken to monitor progress during treatment.
How Is Subcision Performed?
Subcision is usually performed as an outpatient procedure.
Step 1: Skin Examination
The treatment areas are carefully marked.
Step 2: Cleansing
The skin is cleaned thoroughly to reduce the risk of infection.
Step 3: Local Anesthesia
A local anesthetic is administered to maximize patient comfort during the procedure.
Step 4: Needle or Cannula Insertion
A specialized needle or blunt cannula is introduced beneath the skin through a small entry point.
Step 5: Release of Fibrous Bands
The dermatologist gently moves the instrument beneath the scar to release the tethering bands.
A characteristic snapping sensation may sometimes be felt as these bands separate.
Step 6: Completion of Treatment
After all targeted scars have been treated, gentle pressure is applied to minimize bleeding and swelling.
The procedure usually takes 20–45 minutes, depending on the number and extent of scars being treated.
Does Subcision Hurt?
Because local anesthesia is used, most patients tolerate the procedure well.
You may experience:
- Mild pressure
- A pulling sensation
- Temporary discomfort
After the procedure, mild soreness, swelling, or bruising is common and generally improves over several days.
How Many Sessions Are Needed?
The number of sessions varies according to:
- Scar severity
- Number of scars
- Scar type
- Individual healing response
- Combination treatments
Many patients require multiple sessions spaced several weeks apart to achieve optimal improvement.
Your dermatologist will recommend a personalized treatment schedule after evaluating your scars.
Can Subcision Be Combined with Other Treatments?
Yes. Combination therapy often provides better results than a single procedure because acne scars usually involve multiple structural changes.
Depending on the type of scars, subcision may be combined with:
Microneedling
Microneedling stimulates collagen remodeling and improves overall skin texture.
Platelet-Rich Plasma (PRP)
PRP uses growth factors from the patient’s own blood to support healing and collagen production after subcision.
Fractional Laser Resurfacing
Fractional laser treatment may improve skin texture, stimulate collagen remodeling, and address superficial scar irregularities.
Dermal Fillers
Dermal fillers may be used in selected cases to provide additional support beneath certain depressed scars after subcision.
Chemical Peels
Chemical peels can improve pigmentation and superficial skin irregularities when appropriate.
Radiofrequency Microneedling
This combination may further enhance collagen remodeling in selected patients with atrophic acne scars.
Is Subcision Safe?
When performed by a qualified dermatologist using appropriate techniques, subcision is generally considered a safe procedure. Careful patient selection, sterile technique, and proper aftercare help minimize the risk of complications.
Recovery After Subcision
Recovery after subcision is generally straightforward, and most patients can resume their normal daily activities within a day or two. However, the healing process varies depending on the extent of treatment, the number of scars treated, and individual skin characteristics.
Immediately after the procedure, you may notice:
- Mild swelling
- Bruising
- Redness
- Tenderness
- A feeling of tightness in the treated area
These effects are expected and usually improve over the following several days.
What to Expect After the Procedure
The healing process typically progresses in stages.
First 24–48 Hours
You may experience:
- Mild swelling
- Slight discomfort
- Small needle marks
- Temporary bruising
Applying a cold compress, if advised by your dermatologist, may help reduce swelling.
First Week
During the first week:
- Bruising gradually fades.
- Tenderness decreases.
- Minor swelling resolves.
- The skin starts healing internally.
Although the skin may look almost normal externally, collagen remodeling has only just begun.
Following Weeks
Collagen production continues over several weeks to months.
Patients usually notice gradual improvement in:
- Skin texture
- Scar depth
- Overall smoothness
- Skin quality
Patience is important because collagen remodeling is a gradual biological process.
Aftercare Following Subcision
Proper aftercare contributes significantly to successful treatment outcomes.
Your dermatologist may recommend the following:
Keep the Area Clean
Wash your face gently using a mild cleanser after the period advised by your doctor.
Avoid vigorous rubbing.
Avoid Picking the Skin
Do not scratch, squeeze, or pick the treated area.
This reduces the risk of infection and post-inflammatory pigmentation.
Use Sunscreen Daily
Broad-spectrum sunscreen is essential after acne scar procedures.
Sun protection helps:
- Prevent pigmentation
- Protect healing skin
- Improve long-term results
Follow Prescribed Skincare
Use only the products recommended by your dermatologist during the healing period.
Avoid harsh exfoliants until your skin has recovered.
Stay Hydrated
Adequate hydration supports healthy skin healing.
Attend Follow-Up Appointments
Regular follow-up allows your dermatologist to monitor healing and determine the need for additional treatment sessions.
Results After Subcision
Subcision provides gradual rather than immediate improvement.
Many patients begin noticing visible changes within several weeks, while collagen remodeling continues for several months.
The extent of improvement depends on:
- Type of scars
- Scar severity
- Number of treatment sessions
- Combination procedures
- Individual collagen response
Because acne scars vary greatly, no procedure can guarantee complete scar removal. The goal is to achieve meaningful improvement in skin texture and appearance.
Before and After Expectations
Patients should maintain realistic expectations.
Subcision aims to:
- Reduce scar depth
- Improve skin smoothness
- Soften rolling scars
- Stimulate natural collagen production
- Enhance overall facial appearance
Most dermatologists recommend documenting progress with standardized clinical photographs before each treatment session.
Possible Side Effects
Most side effects are temporary.
These may include:
- Bruising
- Swelling
- Mild pain
- Tenderness
- Temporary redness
- Small hematomas
These effects generally resolve with appropriate aftercare.
Possible Complications
Although uncommon when performed by an experienced dermatologist, complications may include:
- Infection
- Prolonged bruising
- Persistent swelling
- Temporary pigmentation changes
- Irregular contour
- Nerve irritation (rare)
- Scar formation (rare)
Careful patient selection and proper technique help minimize these risks.
Can Acne Scars Return After Subcision?
Subcision permanently releases the fibrous bands that are treated. However, new acne lesions can create additional scars if acne remains uncontrolled.
For this reason, active acne should be managed alongside scar treatment to achieve long-term improvement.
How to Maintain Your Results
Long-lasting improvement depends on good skincare and acne control.
Helpful measures include:
- Treat active acne promptly.
- Use sunscreen every day.
- Follow a dermatologist-recommended skincare routine.
- Avoid picking acne lesions.
- Attend scheduled follow-up visits.
- Complete the recommended treatment plan.
