Subcision is a minimally invasive procedure designed to treat certain types of acne scars, particularly rolling scars that are tethered to the underlying tissue. Unlike surface treatments, subcision works beneath the skin, releasing fibrotic bands that pull the skin downward, creating uneven texture.
This article explains how subcision works, who it’s for, the procedure, recovery, and expected results. Check out our comprehensive overview of acne scars.
How Subcision Works
Subcision involves inserting a fine needle under the skin to cut fibrotic bands tethering scars. This releases the skin surface, allowing it to lift and flatten, while also stimulating collagen production in the treated area.
It is particularly effective for rolling scars, which appear as gentle depressions with sloped edges and are difficult to treat with lasers or topical therapies alone. For more on scar types, see Types of Acne Scars Explained.
Who Is an Ideal Candidate?
Subcision works best for patients who:
- Have rolling acne scars with fibrotic bands
- Have stable acne with minimal active breakouts
- Are over 18 and in general good health
- Can follow post-procedure care instructions
Patients with active acne or inflamed skin are not ideal candidates, as the procedure could worsen the acne scars healing.
Procedure Overview
Step 1: Consultation
A dermatologist evaluates:
- Scar type and depth
- Skin tone and sensitivity
- Medical history and acne status
Step 2: Preparation
- Local anesthetic applied to minimize discomfort
- Treatment area cleaned and prepped
Step 3: Subcision Technique
- A specialized needle or blunt cannula is inserted under each scar
- Fibrotic bands are carefully severed
- Multiple scars can be treated in a single session
Step 4: Post-Procedure Care
- Mild swelling and bruising are expected
- Ice packs reduce discomfort
- Avoid strenuous activity for 24–48 hours
Recovery Timeline
- Day 1–2: Mild swelling, redness, bruising
- Day 3–7: Swelling subsides; patients can return to work
- Week 1–2: Bruising fades; skin may feel tender
- Week 3–4: Early collagen remodeling begins
- Month 2–3: Noticeable improvement in scar depth and skin smoothness
Recovery is generally faster than laser resurfacing for rolling scars, making subcision a convenient choice for working adults in Malaysia.
Expected Results
- Flattening of rolling scars
- Gradual improvement in skin texture over weeks
- Can be combined with laser or dermal filler treatments for optimal outcomes
Most patients require 2–3 sessions spaced 4–6 weeks apart, depending on scar severity. Results are long-lasting when combined with acne control and proper skincare.
Combination Treatments
Subcision is often combined with other acne scar treatments:
- Laser resurfacing to improve pigmentation and surface smoothness
- Dermal fillers to lift deeper indentations
- Microneedling or PRP to stimulate additional collagen
Combination therapy is especially effective for mixed scars, addressing both texture and pigmentation.
Risks and Considerations
While subcision is generally safe, minor risks include:
- Bruising and swelling
- Mild discomfort
- Rare: hematoma or infection
Malaysian patients with darker skin types may experience temporary pigmentation, making sun protection and careful post-care essential.
Who Should Avoid Subcision?
- Patients with active acne or inflamed lesions
- Individuals prone to keloid or hypertrophic scars
- Those unable to follow post-procedure care instructions
Proper candidate selection ensures safe, effective outcomes.
Conclusion
Subcision is an effective, minimally invasive solution for rolling acne scars in Malaysia. By releasing fibrotic bands beneath the skin, it flattens depressions, stimulates collagen, and improves overall texture.
Ideal candidates are patients with stable acne, rolling scars, and realistic expectations. Combining subcision with lasers, microneedling, or dermal fillers can enhance results further. Professional assessment ensures the procedure is tailored to scar type, severity, and skin characteristics, maximizing recovery and long-term outcomes.
Frequently Asked Questions
1. What is subcision and how does it treat acne scars?
Subcision is a minimally invasive procedure that releases fibrotic bands under rolling acne scars, lifting depressions and stimulating collagen to improve skin texture.
2. Which acne scars are best treated with subcision?
Subcision works best for rolling scars, while deeper ice pick or boxcar scars may require combination treatments with lasers or chemical peels.
3. Can subcision be done while acne is still active?
No. Active acne increases the risk of new scarring and post-inflammatory pigmentation. Acne should be stabilized first.
4. How long is recovery after subcision?
Most patients experience mild swelling and bruising for 1–2 days, with full recovery over 1–2 weeks. Collagen remodeling continues for several weeks, gradually improving scar depth.
5. How many sessions are needed for noticeable results?
Typically, 2–3 sessions spaced 4–6 weeks apart are required for optimal results, depending on the number and severity of rolling scars.
