Re2o Fine is a finer-particle version of the Re2o extracellular-matrix (ECM) skin booster, a human acellular dermal matrix (hADM) preparation injected into the skin to support dermal remodeling. Rather than simply plumping like a hyaluronic-acid filler, it acts as a biological scaffold: it encourages your own fibroblasts to migrate in and lay down fresh collagen, which is what gives skin its density, bounce, and light-reflecting glass-skin quality.
The “Fine” grade uses a smaller particle size, so it is suited to more superficial placement and finer, more even texture work across the cheeks, under-eye zone, and other delicate areas. Because it works with your biology, results build gradually over weeks rather than appearing instantly, and a short series is typically planned rather than a single visit.
At Reberry Clinic, Re2o Fine is consultation-led and delivered by the clinic’s doctors, who assess your skin quality first and tailor the injection plan. International patients are supported in English, and for those searching near Hongdae (Hongik Univ.) Station, care is provided across our Seoul locations (Gangnam, Myeongdong), easily reached from 홍대입구역.
Re2o Fine is built from a processed human acellular dermal matrix, meaning the donor cells are removed and what remains is the collagen-rich extracellular scaffold that healthy dermis is made of. When micro-injected into the skin, this scaffold does not just add volume; it signals surrounding fibroblasts to infiltrate, remodel, and produce new type I collagen and elastin over the following weeks. In preclinical work, implanted acellular matrix showed fibroblast infiltration and localized new collagen formation, which is the mechanism behind the gradual firming and smoothing patients notice. Because the “Fine” grade is a smaller-particle preparation, it flows through a fine needle for shallow, even placement, making it appropriate for delicate zones and overall texture refinement rather than deep volumizing. This is a different category from a poly-D,L-lactic acid (PDLLA) stimulator or a straightforward hyaluronic-acid skin booster, and the clinic’s doctors choose among these based on whether your priority is structural remodeling, glow, or hydration.

The clinic’s doctors grade your skin across 4 quality markers (firmness, evenness, texture, glow) to decide if the Fine grade suits your goals.
A topical anesthetic is applied for about 20 to 30 minutes so the superficial micro-injections stay comfortable.
The smaller-particle ECM matrix is placed superficially across the target zones in 1 careful session, typically taking 20 to 40 minutes.
Over the next 2 to 8 weeks your fibroblasts infiltrate the scaffold and lay down new collagen, gradually firming and smoothing the skin.
Most plans use 2 to 3 sessions spaced about 3 to 4 weeks apart, with the doctor reviewing progress and adjusting between visits.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
The clinic’s doctors assess your skin quality and goals in English, then confirm whether the Fine grade fits and how many sessions you may need.
After about 20 to 30 minutes of numbing, the fine-grade micro-injections take roughly 20 to 40 minutes depending on the treatment zones.
Re2o Fine is planned as a short series, so the doctor maps your sessions across several weeks rather than a single fixed visit.
Collagen remodeling builds over about 2 to 8 weeks per session, with the fuller effect visible after the series is complete.
Because results depend on your own collagen, gentle skincare, sun protection, and occasional maintenance help sustain the improvement over time.
Re2o Fine is a finer-particle ECM (hADM) skin booster that stimulates your own collagen through a biological scaffold, rather than just adding volume like a hyaluronic-acid filler. It refines texture and density over weeks. You can read more on our glass facial skin page before booking.
Re2o Fine uses a smaller particle size than standard Re2o, so it suits more superficial placement and delicate zones such as the under-eye and fine texture work. Standard Re2o supports broader dermal density. The clinic’s doctors decide which grade fits your skin at consultation, and both may be combined in one plan.
Most healthy adults wanting smoother, denser, more luminous skin are suitable, especially those preferring collagen stimulation over volume-only filler. A consultation confirms your skin quality and goals. Those who are pregnant, breastfeeding, or have an active skin infection should wait, and your doctor will review any medications first.
Discomfort is generally mild because a topical anesthetic is applied for about 20 to 30 minutes before the superficial micro-injections. Most patients describe brief pinpricks. Because the Fine grade is placed shallowly with a fine needle, sensation is usually manageable, and your doctor adjusts technique for delicate zones like the under-eye area.
Downtime is usually minimal, with brief pinpoint marks or slight redness that typically settle within a day or two. Some patients see small bumps that soften as the matrix integrates. You can generally return to daily activities the same day, avoiding heavy makeup, saunas, and vigorous exercise for about 24 hours.
Visible change builds gradually over about 2 to 8 weeks per session as fibroblasts remodel the scaffold and lay down new collagen, not overnight. The fuller effect appears after the planned series is complete. Your doctor reviews progress between visits so the plan stays matched to how your skin responds.
Most plans use a short series of about 2 to 3 sessions spaced roughly 3 to 4 weeks apart, since collagen builds over time. The exact number depends on your skin quality and goals. Your doctor confirms the schedule at consultation and adjusts it based on how each session settles.
Because results come from your own newly formed collagen, they can hold for many months, though skin continues to age, so this is not a one-time fix. Occasional maintenance sessions and good skincare help sustain the improvement. Longevity varies with age, lifestyle, and sun exposure, which your doctor discusses individually.
Yes, Re2o Fine is often staged with hydration boosters, polynucleotide repair, or energy-based lifting for a fuller glass-skin result. Sequencing matters so the skin is not over-stressed. Your doctor may pair it with a Rejuran Healer plan and space treatments appropriately across your visits.
A hyaluronic-acid skin booster mainly hydrates and adds glow, while Re2o Fine provides an ECM scaffold that stimulates lasting collagen remodeling for density and texture. They target different goals and are sometimes combined. You can explore hydration-led options on our glass facial skin page.
Re2o Fine is generally well tolerated when performed by a trained doctor, and in clinical study no serious adverse events were reported for the ECM booster category. Temporary redness, swelling, or pinpoint marks are the most common effects. A consultation screens for contraindications like active infection or pregnancy to keep treatment appropriate for you.
The most common side effects are temporary redness, mild swelling, small bumps, or pinpoint bruising that usually settle within days. Serious reactions are uncommon. Your doctor reviews your medical history and medications beforehand to reduce risk, and you receive clear aftercare guidance so any minor effects resolve smoothly at home.
Keep the area clean, avoid heavy makeup, saunas, and vigorous exercise for about 24 hours, and use gentle skincare with daily sun protection. Because results depend on collagen, a supportive skin care routine helps sustain them. Your doctor gives personalised aftercare based on the zones treated.
