Teosyal in Toronto: Redensity 1 (Skin Booster) and Redensity 2 (Under-Eye Filler)
By Basil Russo, Founder, Bar Beauty Medical, 46 Fort York Blvd, CityPlace Toronto. Clinically reviewed by Shahram Mafazi (IMG, PDD), senior aesthetic injector and trainer.
Short version: Teosyal is the injectable line from Teoxane, a Swiss laboratory. At Bar Beauty Medical we carry two specific Teosyal products: Redensity 1, a skin-quality booster, and Redensity 2, a hyaluronic acid filler designed specifically for the under-eye and tear trough. We do not carry the Teosyal RHA face-volumizing range. For HA face filler such as cheeks, chin, jaw, and folds we use the full Vivacy Stylage range. This page explains exactly what Redensity 1 and Redensity 2 do, who each one is for, and what they cost.

Two Teosyal products, two completely different jobs
The most common mistake people make is assuming Redensity 1 and Redensity 2 are the same family of “filler.” They are not. Redensity 1 is a booster that improves the quality of your skin without adding shape or volume. Redensity 2 is a structural HA filler placed under the eye to correct hollowing. One treats the surface and the texture, the other treats anatomy and shadow. Knowing which problem you actually have is the entire consult.
Teosyal Redensity 1: the skin booster
Redensity 1 is what the industry calls a redensifier or skin booster. Instead of a thick gel that sits in one place to create projection, it is a light, partly cross-linked hyaluronic acid combined with a dermo-restructuring complex of amino acids, antioxidants, vitamins, and minerals. It is delivered in many small micro-injections across an area rather than a few deep boluses, closer to a mesotherapy technique than to traditional filler.
What Redensity 1 actually improves
The goal is skin you can see the difference in, not a change in shape. Patients use it for dull, tired-looking skin that has lost its glow, for fine surface lines and crepey texture, for early laxity where the skin quality has slipped but volume is still fine, and for hydration in skin that drinks moisturizer and stays flat. It works on the face, and also on the neck, the decolletage, and the back of the hands, all areas where thin skin shows age first.
How a Redensity 1 course works
Boosters are a course, not a single visit. Most people start with a short series of sessions a few weeks apart to build the result, then maintain a few times a year. You will not walk out volumized. Over the following weeks the skin looks fresher, more hydrated, and more even, and the effect is cumulative across the series. It pairs well with energy-based treatments like Aerolase and Morpheus 8 for an overall skin-quality plan.
Teosyal Redensity 2: the under-eye filler
Redensity 2 is a different product entirely. It is a hyaluronic acid gel engineered specifically for the tear trough, the hollow that runs from the inner corner of the eye along the top of the cheek. The skin there is the thinnest on the face, so a normal cheek or lip filler placed under the eye holds too much water, swells, and can cast a bluish tint called the Tyndall effect. Redensity 2 is formulated with low water-binding so it integrates smoothly under thin skin and resists puffiness.
Why the under-eye is the strictest area we treat
Tear-trough filler is the treatment we turn people away from most often, and that is a feature, not a flaw. It only works well in the right candidate. If your hollowing is true volume loss, Redensity 2 placed deep on the bone, usually with a blunt cannula to reduce bruising and vascular risk, can erase years of tired-eye appearance. If your real issue is herniated fat pads (eye bags that bulge), fluid retention, or festoons, filler can make it look worse, and the honest answer is a referral for a different treatment. We assess this carefully before we ever pick up a syringe.
What to expect from Redensity 2
Most under-eye corrections use a small amount per side. You may have mild swelling or a little bruising for a few days, with the true result settling at about two weeks. Because it is hyaluronic acid, it is fully reversible with hyaluronidase if you do not like the result or if any product needs adjusting. Under-eye results commonly last twelve months or more because the area moves relatively little. For some anatomy we use Stylage S as an alternative soft gel, and we will tell you which we recommend and why.
What about Teosyal for cheeks, lips, and jaw?
Teoxane also makes a range of volumizing fillers (the RHA and classic Teosyal lines) for cheeks, lips, chin, jaw, and folds. We do not carry those. For HA volume and contour we standardized on the Vivacy Stylage range (S, M, L, XL, XXL, and Special Lips) because the full size ladder lets us match the exact gel to the exact area, and the mannitol-stabilized gel suits the natural results our patients want. So if you came in for “Teosyal cheek filler,” what we would actually use is Stylage, and the consult will walk you through it. See our dermal fillers and lip filler pages for those areas.
What Teosyal treatments cost at Bar Beauty Medical
We publish real prices. Redensity 1 skin-booster sessions are quoted per session at your consult, with a recommended series for the best result. Redensity 2 under-eye correction is quoted per treatment, typically in the range of $800 to $1,200 for both sides depending on how much product your anatomy needs. The full, live menu is on our price list, and consults are always free with a written quote and no pressure to book the same day.
Your appointment, and who treats you
Every visit starts with a free consult where we look at your skin and your anatomy honestly and tell you which treatment, if any, fits. For Redensity 1 we cleanse and numb, then place the booster in micro-injections across the area. For Redensity 2 we cleanse, numb, and place the gel deep and conservatively, usually with a cannula. Both products contain or are used with lidocaine for comfort.
Shahram Mafazi, our senior aesthetic injector and trainer (twenty-plus years, IMG, PDD from the Royal College of Physicians of Ireland), and Jasmine Saggu, our board-certified nurse injector, perform our injectable treatments under the standing orders of medical director Dr. John David Henneberry-Fudge, MD FRCPC (CPSO #95972). The under-eye carries real if rare risk, and the protections against it are anatomy knowledge, conservative dosing, cannula technique, and immediate access to hyaluronidase, which we keep on site.
Frequently asked questions
Is Redensity 1 a filler?
Not in the usual sense. It is a skin booster that improves hydration, texture, and glow. It does not add volume or change your shape. If you want volume, that is filler, and we use Stylage for that.
Is Redensity 2 the same as cheek or lip filler?
No. Redensity 2 is formulated specifically for the thin skin under the eye, with low water-binding so it does not puff. We do not use cheek or lip filler in the tear trough.
How many Redensity 1 sessions will I need?
Most people start with a short series a few weeks apart, then maintain a few times a year. Your injector will set the plan at your consult.
Am I a candidate for under-eye filler?
Only if your hollowing is true volume loss. If you have bulging fat pads, fluid retention, or festoons, filler can make it worse, and we will tell you so and suggest a better option.
Is Redensity 2 reversible?
Yes. It is hyaluronic acid and dissolves with hyaluronidase, which we keep on site.
Do you carry the Teosyal RHA range for cheeks and lips?
No. For HA volume and contour we use the Vivacy Stylage range. We are happy to explain the choice at your consult.
