Acne holes, the pitted or indented scars left behind after breakouts, don’t go away on their own. They form when acne damages deeper layers of skin and the body doesn’t produce enough collagen to fill the gap during healing. The good news: several professional treatments can significantly improve their appearance, and some newer options involve less downtime than you might expect. The right approach depends on what type of scarring you have and how deep it goes.
Why Acne Leaves Holes in Your Skin
When a deep pimple, cyst, or nodule inflames the skin, it can destroy collagen and fat tissue beneath the surface. As the wound heals, your body sometimes can’t rebuild that lost structure completely. The result is a visible dip or pit in the skin where the tissue never fully filled back in. This is different from the flat, discolored marks acne can leave behind, which are surface-level pigment changes that typically fade over months. True acne holes involve structural loss, which is why they persist for years and require treatments that physically rebuild or release the tissue underneath.
Three Types of Acne Holes
Not all acne holes look the same, and identifying yours matters because each type responds best to different treatments.
- Ice pick scars are small, narrow indentations that point sharply downward into the skin, almost like a puncture. They’re often the hardest to treat because of their depth relative to their width.
- Boxcar scars are broader depressions with sharp, defined edges, giving them a box-like shape. They can be shallow or deep.
- Rolling scars have sloping edges and varying depths, making the skin look wavy or uneven. These are caused by fibrous bands pulling the skin surface downward from underneath.
Most people have a mix of all three types, which is why dermatologists often recommend combining treatments rather than relying on a single approach.
Laser Resurfacing
Fractional lasers are one of the most studied treatments for acne holes. They work by creating tiny columns of controlled damage in the skin, which triggers your body to produce fresh collagen as it heals. The surrounding untreated skin speeds recovery. Fractional CO2 lasers, the most common type for deeper scars, typically require one to five sessions spaced several weeks apart. Clinical studies show an average improvement rate of around 38% after two rounds of treatment, which translates to noticeably smoother skin even if scars don’t disappear entirely.
Recovery from each session usually involves several days of redness, swelling, and peeling. Your skin may look sunburned for a week or more, and full results develop over months as new collagen continues to form beneath the surface.
Picosecond lasers are a newer alternative that deliver energy in ultrashort pulses. Instead of relying on heat to remodel skin, they use a photomechanical effect that stimulates collagen production with less tissue damage. Studies comparing them to traditional fractional lasers found similar improvement in scar appearance, but with significantly less post-treatment darkening (hyperpigmentation) and lower pain levels during the procedure. This makes picosecond lasers a particularly good option if you have darker skin, which is more prone to pigmentation changes after laser treatments.
Radiofrequency Microneedling
This treatment combines two approaches: tiny needles that penetrate the skin (typically 2 to 3.5 millimeters deep on the face) and radiofrequency energy that heats the deeper layers of skin. The heat promotes collagen remodeling at a level that standard microneedling alone can’t reach. The needles create channels for the energy to travel directly into the tissue where scarring occurs, rather than heating the skin’s surface.
Radiofrequency microneedling works well for boxcar and rolling scars because it can target a larger volume of tissue beneath each scar. Most treatment plans involve three to four sessions spaced about a month apart. Downtime is generally shorter than with ablative lasers, with redness and mild swelling lasting a few days. You’ll notice gradual improvement over two to three months after each session as the new collagen matures.
TCA Cross for Deep Ice Pick Scars
Ice pick scars are notoriously resistant to lasers and microneedling because they’re so narrow and deep. TCA Cross is a targeted technique designed specifically for them. A dermatologist dips a fine-tipped instrument (often just a toothpick) into a high-concentration acid solution and applies it directly to the base of each individual scar. The acid causes a controlled injury at the bottom of the pit, which triggers the body to produce collagen that gradually fills the scar from below.
Each application takes only seconds per scar. The treated spots frost white immediately, then form small scabs that fall off within a week. Multiple sessions, typically three to six spaced a month apart, are needed to progressively raise the scar floor. This treatment is inexpensive compared to lasers and remarkably effective for the specific problem it targets, though it only works on narrow, deep scars.
Subcision for Rolling Scars
Rolling scars look wavy because fibrous bands beneath the skin physically tether the surface downward. No amount of surface-level treatment will fix a scar that’s being pulled from below. Subcision addresses this directly: a dermatologist inserts a specialized needle or blunt cannula beneath the scar through a tiny puncture and moves it back and forth to break those fibrous strands. Once released, the skin can lift naturally.
For deeper depressions, dermal fillers are often injected immediately after subcision to plump up the area and prevent the bands from reattaching. This combination can produce dramatic results in a single session for the right type of scar. Bruising is common afterward and can last one to two weeks, but the procedure itself is relatively quick. Subcision is frequently combined with laser or microneedling treatments in a multi-step plan to address different scar types at once.
What Topical Products Can (and Can’t) Do
If you’re hoping a cream or serum will fill in acne holes, the honest answer is that topical products have limited power over structural scars. Prescription retinoids like adapalene and tretinoin can stimulate some collagen production and scar remodeling over time, and research supports their use for milder scarring. They work best as a long-term maintenance strategy alongside professional treatments, or as a preventive measure while acne is still active to reduce the severity of scars that form.
Over-the-counter products containing retinol, vitamin C, or niacinamide may improve overall skin texture and tone, making scars less noticeable. But they cannot physically rebuild the volume of tissue lost in a true acne hole. If your scars are deep enough to catch shadows in certain lighting, topical products alone won’t resolve them.
Choosing the Right Approach
The most effective treatment plans are usually combinations tailored to your specific scar types. A common approach for someone with mixed scarring might look like subcision for the rolling scars, TCA Cross for the ice picks, and a series of laser or radiofrequency microneedling sessions to improve overall texture and the remaining boxcar scars. This kind of multi-modal plan, spread over several months, produces better results than any single treatment repeated on its own.
Expect the full process to take six months to a year for meaningful improvement. Collagen remodeling is slow, and most treatments show their best results two to three months after the final session. Improvement in the range of 40 to 70 percent is a realistic goal for moderate scarring with a combined approach. Complete elimination of deep scars is uncommon, but for most people the difference is significant enough that scars no longer dominate how their skin looks.
Cost varies widely depending on the treatments selected and the number of sessions. Laser and radiofrequency sessions typically run several hundred to over a thousand dollars each. Subcision and TCA Cross tend to be less expensive per session. Insurance rarely covers acne scar treatment since it’s considered cosmetic, so it’s worth asking about package pricing if your dermatologist recommends multiple sessions.
