alloClae Adipose Filler in Chicago
Volume that behaves like your own tissue — the fat-derived filler, without the surgery.
alloClae is the first structural adipose filler made for aesthetic use: processed human fat tissue that restores soft, natural volume where your own fat has thinned — no liposuction, no donor-site, no general anesthesia. At Refine by Tulsi, it's placed by a physician who treats it as anatomy, not just product.

What is alloClae?
alloClae is the first structural adipose (fat) filler designed for aesthetic use. Made from processed, sterilized human donor fat tissue, it restores soft, natural-looking volume to the face and body without surgery, liposuction, or a donor site. It adds volume immediately and acts as a scaffold that your own tissue and collagen integrate into over the following months. At Refine by Tulsi in Chicago, every alloClae treatment is placed by a physician, in-office, in under an hour.
Not a synthetic gel. Real adipose tissue.
Most fillers are hyaluronic acid — a gel your body slowly dissolves. alloClae is different in kind: it's processed human fat tissue that keeps the natural 3D "honeycomb" structure of adipocytes along with the surrounding extracellular matrix — the collagen, proteins and growth factors that let it integrate with your own tissue.
It adds volume immediately, then acts as a scaffold your body builds into over the following weeks.
Because it's purified — free oil reduced below 2%, DNA content minimized, and terminally sterilized — it's designed to lower the risks associated with older fat-based approaches. It contains no living cells, so its result doesn't depend on cell survival the way traditional fat grafting does.
alloClae sits alongside our other volume treatments: where hyaluronic acid dermal fillers excel at fine detail and our facial balancing work restores proportion, alloClae adds larger, structural volume — part of our broader regenerative medicine approach.
Immediate structure, then regeneration
alloClae does two things at once — it fills, and it gives your own tissue something to grow into.
Immediate volume
The preserved honeycomb structure provides shape and cushioning the moment it's placed — so you see the contour change the same day.
Tissue integration
Unlike HA gel, it doesn't sit as a separate bubble or migrate. The matrix integrates with the surrounding tissue where it's placed.
Collagen over time
The retained matrix acts as a scaffold, supporting your body's own collagen and tissue to build in over the following weeks and months.
The real difference shows up months later
Every option looks similar on day one. Pick one, then drag the timeline — watch what actually happens under the skin.
HA filler
A synthetic gel that adds volume today — then your body gradually breaks it down.

Illustrative animation for education, not a depiction of a specific result. alloClae is a human cell & tissue product, not an FDA-approved drug or device; longevity varies by area and individual. Your physician will give you specifics at consultation.
Between a filler and a fat transfer
alloClae occupies the space HA fillers and surgical fat grafting leave open — the structure of fat, without the operation.
Independent providers report alloClae lasting roughly one to three years; long-term data is still limited, and your result depends on the area treated and your own biology.

Anywhere fat naturally belongs
alloClae can restore or refine volume in the areas below. Your physician will confirm which are right for you at consultation.
Hip dips
Softens the inward hollow along the outer hip for a smoother, more balanced silhouette.
Contour & curves
Subtle, natural shaping of the buttock and body contour without implants or a surgical BBL.
Post-procedure irregularities
Evens out divots, ripples and asymmetries left after liposuction or prior procedures.
An honest look at candidacy
alloClae may suit you if you…
- Want natural, structural volume without surgery or downtime
- Are lean and don't have enough fat to harvest for a fat transfer
- Want to avoid general anesthesia and a donor-site recovery
- Have contour irregularities after liposuction or another procedure
- Prefer a result that integrates and feels like your own tissue
It may not be right if you…
- Have severe allergen sensitivities or a history of anaphylaxis
- Have an active infection in or near the treatment area
- Are pregnant or breastfeeding
- Want a result that can be fully dissolved later, as HA filler can
- Expect surgical-scale change — that's a different conversation
The only way to know is a consultation. Dr. Kotecha will review your goals, health history and anatomy before recommending anything.
From consult to contour
Consultation
A physician evaluates your goals, anatomy and health history, and maps the areas — and the volume — that fit you.
Treatment
In-office, typically under an hour, with local anesthetic. alloClae is placed with a cannula or fine needle for precision and comfort.
Recovery
Mild swelling or bruising is normal and usually settles within a few days. Most people return to normal activity in 24–48 hours.
Integration
You see volume immediately; over the following weeks the matrix integrates and supports your own collagen.
Physician-placed, not delegated
Dr. Tulsi Kotecha, MD
“For years, the patients I couldn’t fully help were the lean ones — women who wanted contour but had no fat to harvest and no interest in surgery. alloClae changed that. For the first time I can restore real structural volume in the office, with something that behaves like their own tissue. It’s a genuine game-changer for how we approach the body.”
Dr. Tulsi Kotecha, MD
Board-certified in Internal Medicine and Aesthetic Medicine and trained at University College London and the University of Bristol, Dr. Kotecha built Refine by Tulsi around facial balancing and regenerative aesthetics. With alloClae, that means volume placed by a physician who reads it as anatomy — proportion, structure and restraint — and who has invested specifically in results that are safe across all skin tones.

What is alloClae made of?
alloClae is made from donated human adipose (fat) tissue that has been purified and processed. It keeps the natural 3D structure of fat cells and the surrounding extracellular matrix — collagen, proteins and growth factors — while free oil is reduced below 2% and DNA content is minimized. It contains no living cells, and it's terminally sterilized before use.
How is alloClae different from regular filler?
Most fillers are synthetic hyaluronic acid gel, which your body gradually dissolves. alloClae is processed human fat tissue that integrates with the area where it's placed and supports your own collagen over time, rather than sitting as a separate gel that migrates or breaks down. It's generally used for larger, structural volume, where HA fillers are better suited to fine facial detail.
How is it different from a fat transfer?
A traditional fat transfer requires liposuction to harvest your own fat, which means a surgical procedure, a donor site, and a recovery from both. alloClae comes pre-processed and ready to inject, so there's no harvesting surgery and no donor site. That also makes it an option for leaner patients who don't have enough fat of their own to transfer.
Is alloClae FDA-approved?
alloClae is marketed as a Human Cell and Tissue Product (HCT/P) and is regulated under the FDA's tissue regulations, which set requirements for donor screening, processing and safety. That is a different regulatory pathway than an FDA-approved drug or device. Your physician can walk you through exactly what that means and answer any questions before you decide.
How long does it last?
Because alloClae integrates with your tissue, results can be long-lasting — independent providers report roughly one to three years, though long-term data is still limited and outcomes vary by treatment area, your body and your lifestyle. Your physician will give you a realistic range for your specific plan at consultation.
What is recovery like?
alloClae is an in-office treatment, usually completed in under an hour with local anesthetic. Mild swelling, tenderness or bruising at the injection sites is normal and typically settles within a few days. Because there's no surgical harvesting, there's no donor-site to heal, and most people return to normal activity within 24 to 48 hours.
What are the risks?
As with any injectable, possible effects include swelling, bruising, and — less commonly — nodules, asymmetry, infection, or allergic response. alloClae isn't recommended for people with severe allergen sensitivities, a history of anaphylaxis, or an active infection. Choosing an experienced, physician-led provider who knows the anatomy is one of the most important ways to reduce risk, which is why every alloClae treatment at Refine is placed by a physician.
