Why Some Acne Scars Need Subcision
Why Some Acne Scars Need Subcision
Subcision is one of the most effective treatments for certain types of acne scars because it addresses the underlying structural problem rather than just the skin's surface. While lasers and microneedling can stimulate collagen production, some scars remain attached to deeper tissue by fibrous bands that need to be physically released before significant improvement can occur.
What Is Subcision?
Subcision is a minimally invasive procedure in which a specialized needle or blunt cannula is inserted beneath the skin to break up fibrous bands that pull the surface downward.
The procedure aims to:
- Release scar attachments
- Lift depressed areas
- Stimulate natural collagen production
- Improve overall skin texture
- Enhance the effectiveness of other treatments
It is commonly performed under local anesthesia.
Which Acne Scars Benefit Most?
Not every acne scar requires subcision.
It is most commonly recommended for:
- Rolling scars
- Tethered depressed scars
- Broad areas of uneven skin texture
- Scars that remain fixed when the skin is stretched
Ice pick scars and some shallow boxcar scars may respond better to other treatment methods instead.
Why Lasers Alone May Not Be Enough
Laser treatments can improve collagen production and skin resurfacing, but they cannot physically release fibrous scar attachments.
When tethering remains:
- The skin may continue to appear depressed
- Surface treatments may have limited results
- Improvement may plateau
- Scar depth may remain noticeable
In these cases, subcision addresses the problem at its source.
How the Procedure Works
A typical subcision procedure generally involves:
- Cleansing and local anesthesia
- Insertion of a specialized needle or cannula
- Release of fibrous bands beneath the scar
- Stimulation of controlled healing
- Formation of new collagen during recovery
The procedure is usually completed in a relatively short appointment.
Why It Is Often Combined With Other Treatments
Subcision is frequently used as part of a comprehensive treatment plan rather than as a standalone procedure.
Common combinations include:
- Subcision + RF Microneedling
- Subcision + Fractional CO2 Laser
- Subcision + PRP Therapy
- Subcision + Exosome Therapy
- Subcision + Collagen-Stimulating Treatments
These combinations target both structural tethering and collagen remodeling.
What to Expect After Subcision
Recovery varies from patient to patient but may include:
- Mild swelling
- Temporary bruising
- Localized tenderness
- Minor soreness
- Gradual improvement over several weeks
Collagen remodeling continues long after the initial healing period.
How Many Sessions Are Usually Needed?
The number of treatments depends on scar severity and individual response.
General expectations include:
- Mild tethered scars: 1–2 sessions
- Moderate cases: 2–4 sessions
- Severe rolling scars: multiple staged treatments
- Combination therapy may be recommended between sessions
Progress is typically gradual rather than immediate.
Final thoughts
Some acne scars need subcision because the problem lies beneath the surface of the skin, where fibrous bands create persistent depressions that lasers or topical treatments cannot release. By addressing these underlying attachments and encouraging new collagen formation, subcision can play a key role in improving rolling and tethered acne scars, especially when combined with other advanced treatment techniques.
