TEOSYAL PureSense Redensity 1 1x3ml – 15 mg/mL non-crosslinked hyaluronic acid with 0.3% lidocaine
TEOSYAL PureSense Redensity 1 is a CE-marked Class III injectable manufactured by Teoxane. It belongs to the skin booster class: a fluid, non-crosslinked hyaluronic acid gel that distributes evenly through tissue rather than occupying a defined volume. The rest of the Teosyal range is stocked alongside it.
The defining feature of this device is what has been left out and what has been added. There is no crosslinker: the hyaluronic acid chain is unmodified. In its place, Teoxane supplements the phosphate buffer with antioxidants, eight amino acids, pyridoxine and two trace minerals. The indication follows from that composition – skin quality, hydration and prevention of fine lines, not correction of a fold.
Choose Redensity 1 when the objective is dermal quality across the face, neck and neckline, and when a course of sessions is planned rather than a single correction.

How it works
Hyaluronic acid is a constituent of the dermal extracellular matrix whose content falls with age. Teoxane states that the marked fluidity and viscoelastic properties of Redensity 1 allow it to distribute evenly, which maintains an optimal level of dermal hydration and leads to a lasting improvement in skin texture and elasticity. Across the clinical study programme, 70 to 100% of patients experienced an aesthetic improvement of the treated area.
Nothing here is cross-linked. The gel spreads rather than holds.
Treatment areas
| Area | As named in the instructions for use |
|---|---|
| Face | Skin quality and hydration; withered skin marked by signs of ageing |
| Neck and neckline | Skin quality and hydration; neck lines |
| Forehead and periorbital | Prevention of forehead lines and crow’s feet |
| Perioral | Prevention of perioral rhytids |
Volume per point and per session follows the instructions for use. Teoxane states a maximum of 6 mL per session, based on preclinical and clinical data.
Other products indexed for the same objectives: hydration, skin rejuvenation, neck and decolletage.
Administration
Each syringe is supplied with two sterile 30G 1/2″ needles from Teoxane-approved suppliers. A blunt 25G or 27G cannula may be used instead; Teoxane has verified compatibility with the TSK 25G/50 mm and TSK 27G/38 mm cannulas, with an entry point made using a sharp needle of appropriate size. Compatible cannulas and needles are stocked separately. Teoxane names multipuncture and fanning as the techniques for this product. Treated sites are massaged afterwards to distribute the gel evenly, and the instructions for use warn against contact between TEOSYAL gels and quaternary ammonium salts such as benzalkonium chloride.
Safety profile
Common reactions at the injection site (at or above 1 in 100), usually mild and self-resolving: pain, tenderness, erythema, bruising, oedema, induration, papules and itching. Less common (between 1 in 1,000 and 1 in 100): discoloration, inflammatory reactions, infection, temporary loss of sensitivity or paraesthesia, allergic reactions, nodules and implant migration.
Injection into or close to a blood vessel may lead to embolisation, vascular occlusion, ischaemia and skin or tissue necrosis. Teoxane reports that although such events are extremely rare, the most serious cases of vascular occlusion may cause temporary or permanent vision impairment, or cerebral ischaemia or haemorrhage leading to stroke, which can be fatal. If skin whitening, marbling, pain or numbness occurs at any point during the procedure, the injection is stopped.
The product contains lidocaine, which may produce a positive result in a doping test.
Contraindications
- Cutaneous disorders, inflammation or infection at or near the treatment site
- Known hypersensitivity to hyaluronic acid, or a history of severe allergy or anaphylactic shock
- Known hypersensitivity to any ingredient of the supplemented phosphate buffer
- Autoimmune disease
- Pregnancy, breastfeeding, or patients under 18
- Known hypersensitivity to lidocaine or amide local anaesthetics
- Cardiac disease, or treatment for cardiac disease with beta blockers
- Hepatocellular insufficiency or treatment for liver disease
- Epilepsy or porphyria
Teoxane also states that the product is not to be injected into the epidermis, into or close to a blood vessel or nerve, or at depths other than those described in the dosage section, and is not to be combined with peeling, laser or ultrasound-based procedures. This summary does not replace the product-specific instructions for use, published by Teoxane.
Choosing within the range
Redensity 1 is the only PureSense product Teoxane formulates without a crosslinker, and the only one whose buffer carries amino acids, antioxidants and trace minerals. Every other gel in the range is indicated for a wrinkle, a fold or a volume. This one is indicated for the skin itself. In short: Redensity 1 answers a need for dermal quality and hydration over a course of sessions, not correction of a defined defect in one appointment.
Frequently asked questions
Is Redensity 1 a dermal filler?
No. Teoxane formulates it from non-crosslinked hyaluronic acid, and the indication is skin quality, hydration and prevention of superficial fine wrinkles. It does not fill a fold or restore contour; that job belongs to the cross-linked gels in the range.
What is in the supplemented buffer?
Teoxane lists alpha-lipoic acid, glutathione, N-acetyl-L-cysteine, eight amino acids including L-arginine, glycine and L-proline, pyridoxine hydrochloride, zinc acetate dihydrate, copper sulfate pentahydrate and sodium chloride. Hypersensitivity to any of them is a contraindication.
How many sessions does the manufacturer advise?
Two to three sessions at intervals of three or four weeks, followed by a session two to three times a year to maintain the result.
How long does it last?
Teoxane gives an estimated lifetime of at least three months. Duration depends on skin type, the area injected, the volume placed, and the patient’s physiology and lifestyle.
Can Redensity 1 be used in the lips?
Teoxane names the face, the neck and the neckline as the treatment areas for this device. The lips are not among them. Within the Teosyal range the lip indication belongs to PureSense Kiss and RHA Kiss.
