Enlarged pores
Pores look bigger when the scaffold around them loosens. An ECM skin booster restores the structural support over the treatment course, so pores look smaller as the dermis around them rebuilds.
ECM SKIN BOOSTER, DR SAMANTHA TAY
The ECM (Extracellular Matrix) Skin Booster That Rebuilds Your Skin From the Deep Dermis
Most skin boosters hydrate or signal. An ECM skin booster delivers the scaffold itself, into the deep dermis where collagen actually rebuilds.

Concerns an ECM skin booster solves
ECM in Dr Samantha's own words
HA, PDRN or ECM boosters?
Dr Samantha Tay, Medical Director
What is the extracellular matrix, and why does it thin
Your skin is not just the surface you see and touch. Underneath the top layer sits a structural scaffold called the extracellular matrix, or ECM. It is built from collagen, elastin, hyaluronic acid, and other proteins. It gives skin its firmness, bounce, and structural integrity.
From the late twenties onwards this scaffold starts to thin. That is when patients see enlarged pores, loss of elasticity, and skin that begins to look saggy or soft. These are structural changes, not surface ones, which is why most skincare cannot reach them. The fix has to work in the dermis.
How an ECM skin booster works inside the skin
Most skin boosters either hydrate (hyaluronic acid) or signal (polynucleotide boosters like PDRN). An ECM booster takes a different route. Instead of sending a message to the skin, it delivers the actual raw material, the scaffold itself, directly into the deep dermis.
Think of PDRN as a message to your skin to build more collagen. An ECM booster delivers the building materials directly. Once the scaffold is in place, your fibroblasts (the cells that build collagen and elastin) migrate into it and start depositing fresh proteins onto it over three to six months.
The injection depth matters. An ECM booster is placed at roughly 1.5 to 2.5 millimetres, into the deep dermis. Hyaluronic acid and PDRN boosters typically sit higher, in the superficial to mid-dermis. The depth difference is part of why the patient experience differs, covered in the side-effects section below.
Why technique matters more than the product brand
With most skin boosters, the product does most of the work and the injection technique is supportive. With an ECM skin booster, that ratio is closer to fifty-fifty. The depth of the injection (deep dermis, 1.5 to 2.5 millimetres), how the freeze-dried powder is reconstituted at the bedside, and the spacing of the injection points all affect what your skin actually builds onto the scaffold.
The case for going to an experienced injector is stronger here than for a straightforward hyaluronic acid session. Ask any doctor you are considering how many ECM skin booster sessions they have done, how they decide on injection depth per zone, and what they do differently from hyaluronic acid technique.
Is an ECM skin booster safe, and what should you expect
The first question patients ask is about safety. The source material is donor-derived human tissue, processed through a decellularisation step that removes every cell and every fragment of DNA before the scaffold is freeze-dried. Because the cells are gone, your immune system does not recognise the scaffold as foreign tissue. Your fibroblasts migrate into it and treat it as your own.
The second question is about timing. If you are doing this the week before a big event hoping for a dramatic change, this is not the right treatment. The structural work happens slowly. If you are thinking longer term about genuinely improving the quality and structure of your skin over months, that is what an ECM skin booster is built for.
The protocol: three sessions, four to six weeks apart
A typical starter protocol is three sessions, spaced four to six weeks apart. Most patients then move into maintenance, with cadence adjusted to individual skin and lifestyle. One session lays the foundation; consistency over the full course is where the structural change comes from.
Who this is for, and who should start somewhere else first
Suitable for
Suitable for
- Visible scaffold loss: enlarged pores, soft texture, fine lines that have not responded to surface treatments
- Skin already going through Pico Laser, RF microneedling, or another remodelling procedure where the matrix needs to keep up
- Patients age 30 and above with declining ECM density
- Patients thinking long term about skin quality over months, not chasing a result for a single event
- Existing hyaluronic acid or PDRN booster users who want to add a structural-layer treatment alongside what is working
- Patients in good general health, not pregnant or breastfeeding, with no active infection in the treatment area
Take care
Not the right fit for
- Patients who want a visible change inside a week. The structural work takes three to six months.
- Patients who have not yet tried first-line skin boosters. A hydration booster or PDRN is usually the right starting point.
- Active acne, infection, or inflammation in the treatment zone
- Pregnancy or breastfeeding
- Patients on blood thinners, unless cleared by the prescribing doctor
- Patients with a history of severe allergic reaction to injectable products
If an ECM skin booster is not the right next step for your skin, Dr Samantha will say so at consultation and recommend what is.
If you are in the right-hand column above, the smarter first step is usually a hydration booster or a polynucleotide booster like PDRN. See the full skin booster menu for an overview of how the variants compare and which one fits which concern.
What an ECM skin booster session looks like at Nexus
A standard session runs 45 to 60 minutes from check-in to aftercare review. The injection phase is short; most of the time is preparation and recovery.
- 0 to 5 min
Cleanse and assessment refresh
Skin is degreased. Dr Samantha reviews the plan and confirms treatment zones with you.
- 5 to 25 min
Topical anaesthetic
Numbing cream applied to the treatment area. Lidocaine is also added into the injection mix later, so the procedure is more comfortable than the depth might suggest.
- 25 to 30 min
Bedside reconstitution
Dr Samantha reconstitutes the freeze-dried HADM powder with sterile saline and, in many protocols, a small volume of non-crosslinked hyaluronic acid to improve flow.
- 30 to 45 min
Injection phase
Small aliquots placed across the deep dermis using fine needle or microcannula at roughly 1.5 to 2.5 millimetres depth, adjusted per zone.
- 45 to 60 min
Aftercare review and batch record
Cold compress applied. Dr Samantha records the batch and lot number, kept on file for 30 years per HSA CTGTP requirements, and walks you through the week-one aftercare.
What the published clinical trial measured
Independent peer-reviewed trial data shows measurable improvements in pore size, skin texture density, elasticity, and hydration over twenty weeks. Read the full clinical evidence and methodology in our ECM skin booster article.
Side effects, and what to call us about
Suitable for
Common, expected, resolves within a week
- Mild redness for the first day or two
- Light swelling immediately after the session, settles overnight
- Bruising at injection points, more likely if you take aspirin, fish oil, or anti-inflammatories. Can last up to a week.
- Faint needle marks that concealer covers for a few days
- Notable: with an ECM skin booster, you generally do not get the small injection bumps that hyaluronic acid and PDRN boosters can leave on the surface, because the injection sits deeper
Take care
Less common, contact the clinic
- Persistent bruising past a week
- Nodules that take longer than expected to resolve
- Signs of infection: warmth, spreading redness, fever
- Marked asymmetry or severe pain
- Any vision change, rare for any injectable near the midface; explained in full at the informed consent step before any injection
Most patients are back to normal activities the next day. If you see anything in the right-hand column, phone the clinic immediately.
Aftercare: what to do over the first week
- Day 0 to 2
Immediate recovery
Light cold compress for the first evening to reduce swelling. Avoid strenuous exercise, saunas, and steam rooms. No alcohol or aspirin-containing medication for 24 hours. Most patients are back to normal activities the next day.
- Day 0 to 7
Cover and protect
Use a bit of makeup or concealer to cover bruises or needle marks, which can last up to a week. Keep skincare gentle and fragrance-free for the first three days. Broad-spectrum sunscreen on the treated area whenever you are outside.
- Week 1 and onward
Reintroduce your routine
Once all injection bumps have settled (usually by day four or five), reintroduce active skincare. The scaffold is now settling into the deep dermis; the main collagen and elastin work happens silently over the following three to six months.
Whether an ECM skin booster is right for your skin plan
An ECM skin booster is built for patients thinking long term about skin quality. The structural changes happen across three to six months, and consistency over the full course is where the result comes from. If that is what you want, the protocol is designed for it.
Many patients combine an ECM skin booster with a hyaluronic acid booster in the same session: the structural layer and the surface hydration at once. Dr Samantha discusses the right combination based on each person's skin. The protocol she runs for patients is the same one she would consider for herself.
If you have already done your homework and you are ready to ask whether this fits your skin specifically, the next step is a 20-minute consultation with Dr Samantha.
Common questions before booking
Less than most patients expect, and notably less than a PDRN booster. The reason is depth. PDRN sits in the superficial dermis, which is packed with nerve endings, and the technique requires many small, closely spaced injection points. An ECM skin booster goes into the deep dermis, which has fewer nerve endings. Counter-intuitive but real. Numbing cream is applied beforehand, and lidocaine is added into the injection mix as well.
Hyaluronic acid boosters hydrate. PDRN boosters signal your fibroblasts to produce more collagen. An ECM skin booster delivers the physical scaffold of collagen, elastin, and other matrix proteins directly. Hyaluronic acid is a hydrator, PDRN is a stimulator, ECM is a generator. The three are complementary, not competing; Dr Samantha often uses them together in the same plan.
Some patients notice an improvement in skin texture in the first week as the scaffold fills microscopic gaps in the existing matrix. The main biological work, new collagen and elastin being deposited, happens over three to six months. Individual response varies.
Yes, and many patients do. The two address different layers (structural and surface) and can be done in the same session. Dr Samantha decides based on your skin at consultation; it is one of the combinations she uses regularly.
Ask. Technique matters more for an ECM skin booster than for simpler hyaluronic acid sessions. The depth of the injection, how the freeze-dried powder is reconstituted, and the spacing of the injection points all affect what you get out of it. Ask how many ECM skin booster sessions the doctor has performed and how they decide on injection depth per zone.
At Nexus, the first-time session is SGD 950 and the regular session is SGD 1,300. The first figure is an introductory rate for the same session, not a shorter or smaller one. Whether you need a course rather than a single session is decided at the assessment.
Three factors. The product is a regulated tissue-derived material, not a synthetic hyaluronic acid. The bedside reconstitution protocol takes physician time at the start of every session. And the 30-year traceability record-keeping required by Singapore HSA's CTGTP framework adds compliance overhead at every clinic that handles it.
No. Aesthetic skin-quality treatments are paid out of pocket. Medisave covers medically necessary dermatology in narrow cases only; an ECM skin booster is not one of them.
The source material is donor tissue, decellularised so that no cells or DNA remain before the scaffold is freeze-dried. Because the cells are gone, the immune system does not recognise the material as foreign. The 2026 peer-reviewed clinical trial (Lee YI et al., PMID 41828422) reported no serious adverse events. Common side effects are local and transient: redness, swelling, small bruises lasting up to a week. The category is regulated in Singapore under HSA's CTGTP framework with full traceability.
Most patients return to normal activities the next day. Mild redness and swelling settle within the first 24 to 48 hours. Bruising or needle marks can persist up to a week, especially if you take medications that affect bleeding. Concealer covers them. With an ECM skin booster you generally do not get the small surface injection bumps that hyaluronic acid and PDRN boosters can leave behind, because the injection sits deeper.
Phone the clinic immediately. Marked asymmetry, severe pain, vision changes, or signs of infection (warmth, spreading redness, fever) all warrant immediate review. Phone or WhatsApp +65 8691 8303 during clinic hours.
