Subcision With Suction for Acne Scars in a 2026 Split-Face Trial: Cost, Sessions, and Downtime Questions for People With Rolling Acne Scars

In an October 2026 split-face trial, suction-assisted subcision improved atrophic acne scars more than subcision alone, according to the U.S. National Library of Medicine PubMed record. Rolling scars still need multiple sessions, several days of downtime, and per-area budgeting.

Subcision releases scars from below. A needle or cannula cuts the fibrous bands that pull the skin down, so the surface can lift and form new collagen. Revelus Dermatology describes rolling scars as shallow, undulating depressions held down by those bands.

What did the 2026 trial show?

Ovid/Wolters Kluwer lists the randomized split-face trial as "Subcision Versus Subcision With Suction for the Treatment of Atrophic Acne Scars" in Dermatologic Surgery, volume 52, issue 10, pages 989-993, October 2026 the journal listing. That publication record establishes the trial design and timing.

The U.S. National Library of Medicine PubMed record reports that both sides improved significantly, with physician-rated and patient-rated improvement significantly higher on the suction side at p=.002 and p=.026 the PubMed record. An earlier split-face, evaluator-blinded study by Shi and colleagues found only a short-term patient-perceived edge for suction that faded by month four.

Are rolling scars the right target?

Rolling scars matter here because tethering causes the visible dip. When fibrous bands anchor the dermis downward, the surface looks wavy rather than sharply pitted. Cutting those bands directly addresses that mechanism.

Subcision fits that problem more closely than resurfacing alone. It frees the bound skin first, then healing and collagen support the lifted area. People whose main concern is broad, rolling waviness should discuss that pattern specifically with a dermatologist.

How many sessions should you expect?

One New York dermatology practice, Wall Street Dermatology, reports an average of four subcision sessions depending on severity and area treated. The earlier Shi protocol treated both sides with one subcision session, then added 10 suction sessions to one side across 28 treatment areas and 154 treatments.

A single visit is therefore a weak plan. Scars remodel gradually, response varies by area, and follow-up sessions allow adjustment. Ask for a course plan tied to your scar map, not a one-time quote.

How long will recovery take?

Bruising and swelling commonly last about 3-7 days, according to the Dr Davin Lim dermatology practice and Revelus Dermatology the practice recovery guide. Small areas may settle in 1-2 days, while extensive treatment can take 7-10 days.

Deeper bruising or hematoma is common and may need 4-6 weeks to fully resolve. Practical planning helps:.

Schedule treatment away from photographed events for at least one week.
Expect visible bruising even when pain feels mild.
Confirm aftercare, work notes, and review timing before the appointment.

What will you pay in New York City?

Wall Street Dermatology reports subcision at $1,500 to $2,700 per session per area in New York City, excluding any filler the pricing page. That per-session, per-area structure makes the total depend on scar extent and session count.

For rolling scars, multiply that figure across several sessions rather than budgeting once. Filler, if used, adds a separate charge. Get a written per-area quote for a full course before booking.
