Subcision is a minimally invasive and highly effective dermatological procedure for improving depressed acne scars, especially those that give the skin an uneven appearance. This treatment works directly on the fibrotic bands that pull the skin downward, causing deep, retracted marks.
If you struggle with scars that affect facial uniformity and are looking for a real solution, keep reading. In this article, you’ll understand how subcision works, which types of scars can be treated, and why this technique often delivers such satisfying results. Let’s get started.
What is?
Subcision is a procedure indicated for treating depressed acne scars that develop when fibrotic bands form beneath the skin, pulling it downward and creating indentations and unevenness.
How scars form
These scars act like internal “cords” that tug the skin downward. This tension prevents the surface from becoming smooth and even, leaving marks that often cause both aesthetic and emotional discomfort.
How does subcision work?
During the procedure, a dermatologist or plastic surgeon inserts a special needle called a cannula, which has a blunt tip for added safety. With controlled movements, the cannula passes beneath the skin and breaks the fibrotic bands responsible for the indentation.
This release is immediate, allowing the skin to return to a more natural level.
Why use fillers after subcision?
To enhance results, hyaluronic acid fillers are often applied right after the procedure. They help to:
- Fill the released space
- Support the skin
- Stimulate collagen production
- Improve texture and volume in the treated area
This combination provides more even, progressive, and long-lasting results.
Which scars can be treated with subcision?
The procedure is especially recommended for:
Rolling scars
These are wavy scars with soft edges that create an uneven skin surface.
Certain boxcar scars
Depending on their depth and width, boxcar scars can also benefit from this technique.
Wider icepick scars
Although icepick scars are more challenging to treat, some wider types may respond well when subcision is combined with other treatments.
Subcision combined with other treatments: a powerful approach
In many cases, dermatologists combine subcision with other procedures, such as:
- Fractional laser
- Microneedling
- Chemical peels
- Collagen biostimulators
This combination can accelerate results and further improve skin uniformity.
Is subcision really worth it?
If you’re looking for smoother, more even skin with fewer acne scars, subcision is one of the most effective techniques available today—especially when properly indicated by a specialist and combined with complementary treatments.
