A whole variety of factors can affect the condition and appearance of our skin, apart from the natural ageing process. Stress, hormonal imbalance, sun exposure, tobacco and an unhealthy lifestyle can all play a role, resulting in wrinkles, a dull complexion and tired eyes.

Teosyal® is a leading range of injectable fillers, by TEOXANE Laboratories, each designed to perform a slightly different task: Teosyal Redensity 1 is a skin enhancer that improves skin quality and luminosity. Teosyal Redensity 2 is a tear trough filler that reduces dark circles under the eyes, and Kiss is a lip enhancer that plumps up deflated lips for a natural look.

Your face can be redefined and redesigned as gently and naturally as possible with the TEOSYAL® filler range. Contact our clinics in London and Buckinghamshire to book a consultation.

Before & Afters


Hyaluronic acid (HA) occurs naturally within the body, moisturising and hydrating our skin so that it is plump and soft. As we get older, the hyaluronic acid content of our skin decreases, and collagen and elastic fibres disintegrate. This leads to skin that is drier and finer, lines and wrinkles, hollow eyes that create the impression of being tired, and thin lips with drooping corners for a sad-mouthed appearance.

Teosyal® is a range of injectable facial fillers consisting of biodegradable hyaluronic acid, in the form of a gel, with a high hydrating capacity. Skin is naturally plumped, becoming softer in appearance and regaining its tonicity and glow.

Each Teosyal product is designed for a specific treatment: your medical practitioner will give you all the advice you need at your consultation.

Enhancing skin:

  • Teosyal PureSense Redensity [I] is a light reflecting product that’s suitable for rehydrating and revitalising the face and neck. It involves a series of hydrating micro-injections of hyaluronic acid gel across the skin for dermal redensification to correct wrinkles and facial volume loss. The hyaluronic acid filler is spread evenly to create a natural plumped effect, enhancing the quality of ageing skin and restoring radiance and luminosity.

Correcting under eye circles:

  • Teosyal PureSense Redensity [II] Eyes is a hyaluronic acid gel formula with amino acids, antioxidants and vitamin B. It has been specially developed to correct tear troughs and dark circles under hollow eyes to help you look revitalised and refreshed – with results that are natural and long-lasting. This is a light gel adapted for the delicate eye circle area to minimise the risk of bruising. This tear trough filler is slightly hygroscopic (so it attracts very little water), resulting in minimal or no swelling after injecting.

Enhancing lips:

  • Teosyal Kiss is a hyaluronic acid gel injection developed to treat thin and deflated lips. It is designed for reshaping lip contours, increasing lip volume, treating wrinkles around the mouth, supporting lip corners and rehydrating the lips for a natural look and feel.

At your initial consultation with our qualified medical practitioners, we’ll discuss a personalised treatment plan that’s tailored to you. The Teosyal range is specifically designed for different skin areas and outcomes so, for maximum results, your medical practitioner may recommend combining one or more of the Teosyal PureSense fillers.

The results are instant but the definitive effect is visible after a few weeks.

The effect of an injection usually depends on the area in which Teosyal is injected and varies from one person to another. Redensity [I] and [II] can usually last up to one year, while the results with Kiss lip filler are not quite as long lasting due to the fact that we constantly move our lips.

Teosyal hyaluronic acid injections must be administered by a trained medical healthcare professional. Dr Tracy Mountford, owner of The Cosmetic Skin Clinic, is renowned for her light hands and natural looking results. She personally handpicks and trains all of our medical practitioners to the highest level.

The hyaluronic acid in Teosyal dermal fillers is 100% non-animal origin and non-allergenic, no allergy test is required prior to injection.

Treatment takes approximately 30 minutes depending on the area treated.

No, there’s no downtime and you can resume your normal activities after treatment.

Many people find their procedure at The Cosmetic Skin Clinic more comfortable than expected. Our medical practitioners are highly skilled and precise; you should merely feel a light sting on your skin during the injection procedure.

As with any injection, you may experience some slight redness or minor bruising around the treatment areas which should subside after a few days. A numbing cream can be provided to minimise any discomfort.

Both treatments involve injections to treat wrinkles, but botulinum toxin restricts the muscle movement that results in wrinkles while Teosyal is a corrective method that fills out wrinkles and smooths the surface of the skin.

Teosyal Puresense Redensity 1 is known as a Skin Booster thanks to its patented blend of highly concentrated Hyaluronic Acid and essential nutrients

Its specific purpose is to hydrate, rejuvenate, add radiance and redensify the face, neck and neckline. It helps to tackle fine wrinkles and prevent further wrinkles whilst replenishing the skin’s nutrients that have been lost with age.

Teosyal Redensity 2 is a hyaluronic acid-based filler that is specifically designed to treat dark, under-eye circles. The eye area is a delicate area and Redensity 2 is a light hyaluronic acid-based gel that will get great results in this challenging area.

Benefits include:

  • Safety for the delicate eye area
  • Immediate results
  • Natural under eye correction results
  • Delays further ageing of the eye contour
  • Light consistency gel
  • Contains a cocktail of 14 essential natural skin nutrients

Teosyal Kiss is an injection of hyaluronic acid gel designed to enhance lips that are thin and deflated. For a natural look and feel, it reshapes lip contours, increases lip volume, treats wrinkles around the mouth, supports lip corners, and hydrates the lips.

The products in the Teosyal range are a popular option for improving skin quality and dark circles under the eyes for both men and women. We provide a discreet service for all our patients.
