Laser Coring uses a 2910 nm fiber laser to create precise tissue channels beneath the skin, remodeling collagen without the downtime of traditional ablative resurfacing.
Overview
Laser Coring is a proprietary treatment mode on the UltraClear® 2,910 nm cold ablative fiber laser (Acclaro Medical). Unlike traditional laser resurfacing, which vaporizes the outer skin layer, Laser Coring creates precise columns of tissue removal deeper in the skin. This targeted coring triggers collagen remodeling from within, addressing deep wrinkles, scars, and skin laxity without disrupting the entire surface. Laser Coring should not be confused with mechanical micro-coring (Ellacor), which pursues the same aesthetic goal using a different technique.
The 2910 nm wavelength is highly absorbed by water in the skin, allowing the laser to precisely ablate targeted tissue while minimizing collateral thermal damage. This cold ablative approach protects surrounding skin and shortens recovery. Because the laser can be tuned across multiple depths and densities, providers customize treatment to each patient’s anatomy, concerns, and Fitzpatrick skin type. The laser doesn’t create the result. The provider does.
TL;DR Summary
TL;DR: Laser Coring uses the UltraClear 2910 nm cold ablative fiber laser to remove precise columns of tissue beneath the surface, triggering collagen remodeling without resurfacing the entire skin surface. It treats deep wrinkles, scars, and skin laxity across Fitzpatrick skin types I to VI. Most patients need two to three sessions spaced four to eight weeks apart, with three to seven days of downtime.
The cost of Laser Coring depends on treatment area, treatment depth, number of sessions, and provider expertise. A single-session Laser Coring treatment typically costs more than standard non-ablative resurfacing but less than fully ablative CO2 resurfacing. Request an itemized quote during your consultation.

Most patients see optimal results from two to three sessions spaced four to eight weeks apart. Insurance does not cover Laser Coring because it’s classified as cosmetic. Many clinics offer package pricing for multi-session plans or combine Laser Coring with adjunct skin treatments.
Laser Coring works by combining fractional laser ablation with tissue coring in a single treatment. The 2910 nm wavelength is highly absorbed by water in the skin, allowing precise energy delivery with minimal collateral thermal damage. Multiple treatment modes address different depths and concerns.
Laser Coring addresses deep wrinkles, rhytides, acne scars, surgical scars, skin laxity, photoaging, and textural irregularities across the face and neck.
A session typically runs 30 to 60 minutes, including topical numbing, treatment passes, and post-treatment skin protection.
Most healthy adults are candidates, including Fitzpatrick skin types I-VI. Patients with active infections, recent isotretinoin use, certain autoimmune conditions, or pregnancy are not eligible.
Expect three to seven days of social downtime depending on treatment depth. Skin moves through redness, mild swelling, and gradual healing before revealing improved texture.
Laser coring removes narrow full-thickness columns of skin rather than treating the surface alone, so it reaches concerns that resurfacing cannot correct. The concerns below share a common cause: there is more skin than the underlying structure can support. Removing tissue, not just heating it, is what addresses them.
Laxity is a tissue quantity problem before it is a collagen problem. Coring physically removes skin so the surrounding tissue draws inward as it heals, tightening the midface and jawline without incisions. Most patients notice the change first in how their lower face sits at rest.
Deep folds re-form after resurfacing because the excess skin creating them is still present. Coring shortens that skin across the treatment area, so the fold has less tissue to collapse into. The realistic outcome is meaningful softening and a shallower crease, not erasure.
Mild skin excess along the lower face and neck falls in the gap between doing nothing and having surgery. Coring addresses it by removing a measurable percentage of skin surface area per session, which is why results build progressively across a planned treatment series.
Traditional laser resurfacing removes the top layer of skin, then waits for it to rebuild. Laser Coring goes deeper in specific channels, triggering collagen remodeling from within while leaving most of the surface intact. That difference is why recovery is measured in days instead of weeks. Mechanical micro-coring (Ellacor) is a separate technology using hollow needles rather than laser energy.
Most patients see optimal results from two to three sessions spaced four to eight weeks apart. Deeper concerns may benefit from additional sessions. Your provider builds a plan based on skin type and goals.
Yes. The 2910 nm wavelength has clinical evidence supporting safe use across Fitzpatrick skin types I-VI, unlike some traditional resurfacing lasers. Your provider adjusts settings by skin type to reduce complication risk.
Results can last around twelve to eighteen months with consistent sun protection and quality skincare. Collagen remodeling continues for months after treatment. Some patients see longer-lasting improvement, while others may return for maintenance sessions every twelve to twenty-four months to preserve outcomes.
Laser Coring is not appropriate for patients with active skin infections, recent isotretinoin use, certain autoimmune conditions, or a history of keloids. Patients who are pregnant or breastfeeding are also not candidates. A thorough consultation determines whether treatment is right for your situation.
