The best dermatologist treatments for deep acne scars are combinations matched to scar type, skin type and severity. Dermatologists pair laser resurfacing, subcision, fillers, and excision methods because no single procedure fixes all deep scars. Deep scars are atrophic scars. They sit below surrounding skin after inflammation destroys collagen.

Why combination treatment works best
Dermatologists assess whether pits are broad and rolling, narrow and deep, or wide and sunken. They then build a plan around that pattern, skin tone, and scar severity.
Mayo Clinic notes through its care-network scar guide that combined procedures are often needed because no one treatment suits every deep scar. That approach also lets the doctor treat different scars in the same area differently. A rolling scar may need release from below, while a nearby ice-pick scar needs treatment inside the pit.
How lasers and subcision lift rolling scars
Rolling scars look wide and wavy because bands of fiber pull the skin down. Subcision places a needle under the scar to loosen those bands, letting the depression rise as new collagen forms. Pairing release with resurfacing improves the result.
A split-face trial reported 54.7% recovery with subcision plus fractional CO2 laser versus 43% with laser alone, according to the study record at the U.S. National Library of Medicine. That difference matters for broad, shadowed cheeks.
What fills sunken scars
Soft-tissue fillers add volume under depressed scars. Options include hyaluronic acid, collagen-based Bellafill, and poly-L-lactic acid.
The lift is temporary for most fillers and needs repeat treatment. In January 2015, FDA approved Bellafill, a polymethylmethacrylate-collagen gel, for moderate-to-severe atrophic cheek scars in adults over 21, as described in the FDA approval notice summarized by HealthDay. It was the first filler cleared for acne scars.
- Ask whether your scars are shallow enough to plump or tethered enough to need release first
- Ask how long the chosen filler lasts and when retreatment is due
- Ask how filler will be sequenced with laser or subcision
What treats narrow, deep ice-pick scars
Ice-pick scars are narrow pits that go straight down. They respond poorly to resurfacing alone because the walls are steep and deep.
Dermatologists place high-concentration TCA acid inside the pit to trigger collagen, a method called TCA CROSS. They also cut out single deep pits with punch excision, then close with stitches or a small graft. Dermabrasion is reserved for more severe scarring.
Who needs a pigment-safe plan
Ablative lasers, dermabrasion, and deep peels carry higher risk of pigment change, scarring, or keloid in darker skin or with keloid history. Color change can last months and may stand out more than the original pit.
Tell your dermatologist about past dark marks, light marks, keloids, and slow healing. Ask which sequence lowers heat and wound depth while still treating depth, and what sun protection and follow-up are required.
