Deusaderm complications: lumps, bulges, white bumps and what can help

What is Deusaderm, and what can go wrong?

Deusaderm is an injectable collagen gel, and most treatments with it go smoothly; when problems occur, they are usually lumps, an overfilled look or pale bumps where the gel sits too close to the surface. It is made in Taiwan from purified type I collagen of porcine (pig) origin, cross-linked so that it lasts longer, and some versions contain a numbing agent. It is placed in the dermis, the deeper layer of the skin, and is marketed for dark circles and hollows under the eyes, as well as fine lines and wrinkles.

Because Deusaderm is collagen rather than hyaluronic acid, the usual dissolving enzyme does not work on it, and that shapes how any problem is corrected. For how SkinRev Lab approaches filler problems in general, see filler correction at SkinRev Lab.

The problems people ask about most:

• Lumps and nodules: firm spots under the skin, appearing early or months later.
• An overfilled or bulging look: a ridge, bag or puffy fullness under the lower lid.
• Pale or whitish bumps: collagen showing through thin under-eye skin.
• Uneven results: one side fuller than the other, or a lumpy edge.
• Less often: inflamed or delayed nodules, an allergic reaction or infection.
• Rarely: a blocked blood vessel, which is an emergency with any filler.

Collagen fillers and collagen stimulators are often confused. For the difference, and how their lumps compare, see collagen injection complications.

How common are Deusaderm side effects?

Mild, short-lived side effects are common after collagen fillers and lasting problems are uncommon, although published data on Deusaderm itself are limited. Most of what is known comes from closely related porcine collagen fillers and from filler research in general. A review of dermal filler complications found that most adverse reactions are mild and short-lived, such as bruising and swelling, and that serious events are rare (Funt and Pavicic, 2013).

• A 2024 trial of two porcine collagen fillers from the same manufacturer, injected into the folds beside the nose in 252 adults, recorded nodules (lumps under the skin) in roughly 1 in 4 to 1 in 3 participants in each group, alongside swelling, tenderness and bruising. Almost all side effects were mild, most device-related effects settled within 30 days without lasting effects, and no allergic reactions were reported. The manufacturer sponsored the trial (Yang and colleagues, 2024).
• An older study of a different porcine collagen filler in the lips found multiple nodules in 16 of 20 women, some still visible more than a year later, and the authors advised against using it in the lips (Braun and Braun, 2008).

Two points follow. First, some early firmness or lumpiness is common and often settles. Second, the area matters: lumps and visible material show more readily where the skin is thin or moves a lot, such as the lips and lower eyelids. The trial above did not study the under-eye area, so its figures may not apply there. Your doctor will advise how this applies to you.

Lumps and nodules after Deusaderm

A lump after Deusaderm is often collagen that sits unevenly, too close to the surface or in a larger amount than the area can carry, and what helps depends on when it appeared and whether it is inflamed. Doctors sort filler lumps by timing and by signs of inflammation, because the two groups are managed differently (Funt and Pavicic, 2013; King and colleagues, 2016).

• Lumps at the time of injection or within hours: usually down to where the product was placed. Some firmness in the first two weeks is swelling around the gel and often settles.
• Firm lumps that persist: typically cool, firm, well defined and not tender. These are usually collagen sitting where it was placed, and they can soften slowly as the body absorbs it.
• Inflamed nodules: red, warm, tender or growing, sometimes weeks or months later. Infection or an immune reaction is possible, so a doctor should assess them.
• Granulomas: rare, firm lumps from an immune reaction to the material, typically appearing months to years after injection.

What may help, depending on the type (your doctor will advise which suits you):

• Time and review for small, non-inflamed lumps, with no more collagen in that area meanwhile.
• Antibiotics where a doctor suspects infection after examining you.
• Medicine injected into the nodule for inflamed or granulomatous nodules, once infection has been treated or ruled out; it can calm inflammation but can also thin the tissue, so it is used cautiously.
• Referral for removal of a persistent, well-defined lump, as a last resort.

Massage does not dissolve cross-linked collagen. A doctor may occasionally suggest gentle moulding of a soft, early lump, but a red, warm, tender or growing lump should not be massaged. For lumps after other fillers, see filler lumps and nodules.

Overfilled, puffy or bulging under-eyes

An overfilled or bulging look under the eyes after Deusaderm often comes from too much collagen in one area, top-ups given before earlier product has been absorbed, or placement that does not suit the under-eye. The skin here is some of the thinnest on the face, so small excesses can show as a ridge, bag or shelf under the lower lid.

How it can look:

• A sausage-like ridge or shelf along the lower lid.
• Fullness that bunches up or looks heavier when you smile.
• One side fuller than the other, or a lumpy edge where the collagen ends.

What can look similar:

• Swelling across the upper cheek (malar oedema): fluid swelling, reported with all fillers placed in the under-eye hollow; it needs to be told apart from overcorrection (Funt and Pavicic, 2013).
• Eye bags: often fat bulging forward from around the eye, which filler can soften at the edge but cannot remove; see eye bags.
• Older hyaluronic acid filler: many people have had more than one product under the eyes over the years, so the fullness may be a mix.

What may help: stopping further top-ups is the first step. Mild fullness may ease as the body gradually breaks the collagen down over months. Where hyaluronic acid filler is also present, that part can be dissolved, which sometimes reduces the bulk enough. A defined, persistent lump of collagen is managed as described above. For the wider picture, see signs of too much filler and tear trough filler problems.

White or yellowish bumps under the eyes

Pale, whitish or yellowish bumps under the eyes after Deusaderm often mean collagen is sitting too close to the surface of very thin skin. They usually reflect where the collagen sits rather than damage to the skin, and they behave differently from the blue tint seen with hyaluronic acid.

• Why they look pale: collagen gel is not clear, so near the surface it tends to show as a pale bump or ridge. Superficial hyaluronic acid, a clear gel, scatters light and looks blue instead (the Tyndall effect).
• Where they appear: mostly along the lower lid and tear trough; visible material is more common where skin is thinner (Funt and Pavicic, 2013).
• How they feel: often small and firm, and not usually sore.

Not every white bump is filler. Milia, which are tiny white cysts, and syringomas, which are small skin-coloured or yellowish bumps, are both common under the eyes and can look similar, so a doctor should examine them before anything is done. See milia and syringomas.

What may help:

• Time, as some superficial collagen softens and fades as it is absorbed over months.
• No further collagen in that area until it has been assessed.
• Make-up to disguise the bumps in the meantime.
• For bumps that persist and bother you, your doctor can advise on further options; the enzyme used for hyaluronic acid does not help here.

Do not squeeze, pick or puncture a bump at home, as this risks infection and scarring. For the blue tint seen with hyaluronic acid, see Tyndall effect after filler.

Can Deusaderm be dissolved with the enzyme hyaluronidase?

No. Hyaluronidase, the enzyme used to dissolve hyaluronic acid filler, acts on hyaluronic acid only, and Deusaderm is collagen. The enzyme is very useful for lumps and overfill from hyaluronic acid filler, but it does not break down collagen gel.

What this means for you:

• No quick reversal: there is no injection that removes Deusaderm within days.
• Gradual natural breakdown: the body breaks collagen down with its own enzymes. The manufacturer says the gel is absorbed over several months, varying with the site and technique, and coverage of its 2025 launch in the Philippines described results lasting around 8 to 12 months.
• Lumps may outlast the result: in the older study of a different porcine collagen filler in the lips, some nodules regressed over many months, but some were still visible after more than a year (Braun and Braun, 2008).
• No collagen-dissolving shortcut: in that same study, an enzyme that breaks down collagen did not dissolve the nodules (King and colleagues, 2016).

The enzyme still has a role if hyaluronic acid filler is also present, for example from earlier under-eye treatments. Ultrasound can show where filler sits and suggest whether a lump is hyaluronic acid or another material, though not always with certainty, so that the enzyme is used only where it can work. That is why knowing what was injected, and when, matters so much. For how dissolving works, see dissolving hyaluronic acid filler.

Allergy, infection and other less common problems

Allergic reactions and infection are uncommon after Deusaderm, and a blocked blood vessel is rare, but each needs prompt medical attention, so it helps to know the signs.

• Allergy: older bovine (cow) collagen fillers needed a skin test first because of allergy risk (Braun and Braun, 2008). Deusaderm uses porcine collagen processed to remove the parts of the molecule most linked to reactions, and the 2024 trial above reported no allergic reactions. A reaction is still possible and may show as itching, redness or swelling at the treated sites.
• Infection: a red, hot, increasingly painful swelling, especially from about day 3 to day 14 after injection, is more likely to be infection and needs same-day review (King and colleagues, 2016). Infection can occasionally appear much later.
• Delayed inflamed nodules: lumps that turn red or tender weeks or months later, sometimes after an illness, need assessment rather than waiting.
• Blocked blood vessel: rare with any filler. Pale, white, dusky or mottled skin, or pain that keeps rising, during or after injection is an emergency; any change in vision needs emergency care at once.

Before treatment, tell the doctor about any allergy to collagen or numbing agents, any autoimmune condition and any past severe allergic reaction; people with these were excluded from the 2024 trial.

If you cannot reach the provider who treated you, any doctor can assess urgent symptoms. For swelling patterns after filler, see filler swelling: what is normal.

Warning signs: what is normal and when to get help

Mild swelling, redness, tenderness and small bruises in the first few days are normal after Deusaderm; spreading redness, heat, rising pain, pus, fever or a change in skin colour are not. Use the table as a general guide, and contact your provider or a doctor if you are unsure.

How Dr Sin Yong assesses and corrects Deusaderm problems

At SkinRev Lab, Dr Sin Yong, medical adviser, assesses problems after Deusaderm by taking a full history of previous treatments, examining the area and, where useful, scanning it with ultrasound to see where the material sits. Because collagen cannot be dissolved with an enzyme, the aim is to identify what the lump or fullness is before deciding whether to wait, treat or refer.

What helps the assessment:

• The product name, dates and number of sessions, and any earlier fillers in the same area.
• Photos from before treatment and since the problem began.
• Any recent illness, allergy or autoimmune condition, and your current medicines.

What the assessment looks at: whether a lump is inflamed, how deep it sits, whether it is collagen, hyaluronic acid or swelling, and whether eye bags or fluid are part of the picture. Ultrasound can suggest the type of material but is not always certain, so the treatment history still matters.

What correction may involve, where appropriate:

• Observation and review where the change is mild and likely to soften.
• Dissolving any hyaluronic acid filler found in the same area, in small, staged doses.
• Medical treatment first for an inflamed or infected nodule.
• Referral for surgical removal of a persistent, well-defined lump.

Doing nothing can be the right advice, and correction cannot shorten every problem. Dr Sin Yong explains what is realistic before anything is done, and correction is priced at consultation. It is also worth contacting the provider who treated you, as they hold your treatment records. You can see how mapping works in the ultrasound filler mapping video.

How to lower the risk: questions to ask before Deusaderm

The most useful way to lower the risk is to have collagen injected by a doctor who assesses the under-eye first, explains the product, depth and amount, and reviews the result before any top-up. These questions help:

• Who is injecting, and how much experience do they have with the under-eye area?
• What exactly is the product, and are its name and batch written down for you?
• Is my concern suited to it? Eye bags from fat, and dark circles from pigment, may need a different approach.
• How much is planned, and at what depth? Conservative amounts placed at the planned depth help lower the risk of bulges and visible bumps.
• When is the review, and how long should I wait before any top-up?
• What is it made from? Deusaderm comes from pig collagen, which matters if you avoid pork-derived products.

Tell the doctor about: any allergy to collagen or numbing agents, autoimmune conditions, recent infections or planned dental work, pregnancy or breastfeeding, and every filler you have had in the area.

An older study linked a different porcine collagen filler in the lips with frequent nodules, and its authors advised against lip use, so ask carefully before collagen is placed there. A doctor who suggests a smaller amount, a different treatment or no treatment is often protecting your result. For dark circles from other causes, see dark eye circles.
