Subcision for acne scars: restoring smooth skin, no more worries about acne scars
Are you suffering from long-standing acne scars?
- The skin surface is not smooth, with various shallow and deep indentations making you lose confidence every time you look in the mirror
- Spending a lot of time, effort, and money on treatment but the results are still not as expected
- Acne scars are persistent, deep, and difficult to conceal even with careful makeup
- Every time you take photos or meet others is a time of feeling self-conscious
The truth is that long-standing acne scars cannot fade just by applying topical medication or skincare at home. What the skin needs is an intensive treatment regimen, combining multiple medical methods such as laser, meso injection, skin peel, and subcision to impact the scar tissue, thereby filling in the acne scars.
What is subcision for acne scars?
Subcision for acne scars, also known as scar subcision, is an intensive treatment method aimed at releasing the fibrotic tissue bands located under the scar base, the reason why acne scars are pulled down and cannot fill up on their own over time.
Unlike methods like laser or microneedling which mainly create surface damage to stimulate skin regeneration, subcision directly impacts the contracting fibrotic tissue, both releasing the scar base and creating a localized collagen proliferation signal, helping the scar base have conditions to lift naturally and new skin tissue to be formed more stably.
There are currently 3 common subcision techniques for acne scars at specialized Clinics:


Subcision using medical needles
Using a specialized sharp-tipped needle, inserted under the skin to cut the fibrotic tissue bands contracting the scar base. The direction of the needle insertion will be flexibly adjusted depending on the depth and width of the scar, in order to thoroughly release the fibrotic tissue while still ensuring safety for healthy tissue.


Using a blunt-tipped cannula inserted under the skin to gently separate the fibrotic tissue, limiting damage to healthy tissue, blood vessels, and nerves, causing less pain and less bleeding. This technique is particularly suitable for cases of widespread rolling scars and deep scars.


Subcision using medical CO2 gas
Using high medical compressed gas pressure to separate the skin layers, helping reduce the pulling force on the scar base and supporting a faster recovery process. This method is suitable for cases of acne scars with soft or newly formed fibrotic tissue, while efficacy will be more limited for long-standing scars with hardened or too deep fibrotic tissue.
Who should get subcision for acne scars?


- People with rolling scars or deep boxcar scars, commonly seen after acne, chickenpox, or trauma
- People who want to combine multiple methods to increase recovery speed and fill scars more effectively
- People currently without skin infections, underlying medical conditions, or not taking medications that affect the wound healing process
How many subcision sessions are needed to see efficacy?
The efficacy of subcision for acne scars depends on the type of scar, depth, and each person’s natural collagen proliferation ability.
Normally, 3 – 6 treatment sessions are needed, spaced 4 – 6 weeks apart, to achieve optimal results. After a few weeks, the natural tissue and collagen regeneration process takes place, helping the scar base gradually lift over time.

Should subcision for acne scars be combined with other methods?


Additional intensive regimens can be combined to increase the efficacy of filling scars, promoting the skin restructuring process, and improving post-inflammatory hyperpigmentation (PIH) conditions if any.
Methods frequently combined with subcision include:

Trifill Pro – What’s special about the pneumatic subcision device?


Trifill Pro pneumatic scar subcision device at Doctor Acnes Clinic
Trifill Pro is a specialized medical device developed by MCURE Co., Ltd (South Korea), applying high-pressure medical pneumatic scar subcision technology. Instead of using needles like traditional subcision methods, Trifill Pro uses a flow of pure CO2 gas to break the fibrotic bands under the scar base, helping fill acne scars and restructure the skin foundation more effectively.
The major advantage of this technology is reducing swelling and bruising, causing less pain, and requiring almost no downtime. With the ability to visibly improve the skin surface while still providing a gentle experience, Trifill Pro is currently being frequently applied at Doctor Acnes Clinic in treating acne scars and large pores.
When combined with fractional CO2 laser, RF microneedling, or chemical skin peels, this device contributes to enhancing the efficacy of comprehensive skin regeneration.

Frequently asked questions about subcision for acne scars


How long does it take to recover from subcision for acne scars?
Normally, the skin will recover after about 1 – 2 weeks. During this time, proper care is needed so the skin recovers quickly and scars fill up better.
Is subcision painful?
Subcision for acne scars can cause pain during the procedure, especially when the needle comes into contact with the fibrotic tissue under the skin. However, local numbing cream will be used to minimize the pain sensation, helping the treatment process become more comfortable.
Does subcision for acne scars have side effects?
Subcision is an invasive procedure, so some side effects such as infection, inflammation, prolonged bruising, or keloid scars can still occur if not performed with the correct technique. In some rare cases, dissecting too deeply can affect small blood vessels or nerves under the skin.
To limit risks, the procedure needs to be performed by highly specialized Dermatologists, with sterile tools and strict infection control processes.
How to perform skincare after subcision for acne scars?
After subcision, the skin needs to be gently cleaned every day and continuously moisturized with prescribed restorative products. Absolutely avoid sun exposure for at least the first 7 days, limit makeup or using products with strong active ingredients. Do not touch or impact the treated area to avoid infection and help the scar tissue recover better.
