How might CellREDM help acne scars?

Depressed acne scars form where inflammation destroyed collagen and left the dermis thin or tethered. CellREDM delivers an extracellular matrix (ECM), the structural framework that normally surrounds skin cells, into the scarred layer. The idea is to provide a scaffold that supports the skin's own repair, so that the dermis may become thicker and more even over time.

Unlike filler, CellREDM is not intended to lift a scar instantly. Its role is regenerative, which is why it is usually part of a longer plan for acne scars rather than a one-off fix.

Who is CellREDM for acne scars suitable for?

People with rolling scars or shallow boxcar scars across the cheeks or temples
Skin that looks thin, crepey or uneven around scarred areas
Those who have stable acne and want to improve texture
Patients who want a booster that pairs with laser resurfacing

When it may be less suitable

Deep icepick scars usually need targeted techniques, and raised scars need a different approach altogether. Treatment is usually postponed if acne is very active, if there is infection in the area, during pregnancy or breastfeeding, or while certain medications are being taken. Isotretinoin use should always be mentioned at consultation.

What to expect during a CellREDM session

Diagnosis: the doctor maps scar types and decides which areas will receive CellREDM and which need other methods.
Numbing: topical anesthetic is applied for around 20–30 minutes.
Injection: CellREDM is placed into the dermis with fine needles or a device, concentrating on scarred zones.
Aftercare: a soothing product is applied. Small raised bumps at injection points are normal and usually flatten within a day or two.

Most people can return to everyday activities the same day. Avoid makeup on injection points for about 24 hours, and skip saunas, alcohol and intense exercise for a day or two.

How many sessions are typical?

A common plan is 3–5 sessions about four weeks apart. Collagen remodeling takes time, so changes are usually assessed one to three months after the series begins. Some people return for maintenance every few months. Results vary by individual, and complete scar removal is not a realistic goal.

Which combinations work well with CellREDM?

Re:berry's approach is to combine tools for different scar features:

Laser resurfacing, such as PicoSure Pro or fractional approaches, for scar edges and surface texture
Rejuran Healer to support skin quality and healing between laser sessions
Exosome therapy after laser to support recovery
Genesis laser if red post-acne marks remain

Combinations are usually staged rather than done all at once, and the doctor will explain the spacing.

What are the alternatives to CellREDM?

If CellREDM is not the right fit, other routes include Rejuran Healer for acne scars, exosome therapy for acne scars, PDRN boosters and laser-led plans. Our Rejuran Healer vs CellREDM comparison explains how the two differ in ingredients, feel and typical use.

How do you prepare for a CellREDM session?

Avoid blood-thinning supplements such as fish oil or high-dose vitamin E for several days if your doctor agrees.
Postpone treatment if you have a cold sore, active breakout cluster or sunburn in the area.
Arrive without heavy makeup so numbing can start promptly.
Plan a quiet evening afterward; injection bumps are more noticeable in the first few hours.

What results are realistic?

Many patients describe scarred areas as looking softer and less shadowed after a full series, with skin that feels thicker and more even. Rolling scars often respond better than sharp-edged or very deep ones. Progress photos taken under the same lighting help you and the doctor judge change objectively, since day-to-day lighting makes scars look very different.

Side effects to know about

Expect pinpoint redness, small bumps and possibly bruising. Less commonly, prolonged swelling, lumps, infection or an acne flare can occur. Contact the clinic if you notice increasing pain, warmth or discharge.

Planning CellREDM in Hongdae

Because the series runs over several months, CellREDM typically suits Seoul residents and repeat visitors. Visitors can start with a consultation and first session, then discuss follow-up at another Re:berry branch. Pricing depends on the amount used and the combination plan, and is confirmed in writing at consultation. Book via our Booking page.

Is CellREDM painful for acne scars?

Numbing cream is applied first, so most people feel pressure and light stinging rather than strong pain. Scarred areas can be a little more sensitive than smooth skin. Discomfort usually fades within minutes after the session ends, leaving mild tenderness at injection points.

Can CellREDM be done on the same day as laser?

Some clinics combine boosters and laser in one visit, while others stage them a few weeks apart. The choice depends on your skin's sensitivity, the laser intensity and your schedule. The doctor will decide the safest sequence for you at consultation.

How is CellREDM different from filler for scars?

Filler adds volume under a scar for an immediate lift, while CellREDM provides an extracellular matrix intended to support the skin's own regeneration over time. CellREDM is typically used for overall scarred texture, while filler is reserved for selected deep depressions.
