TEOSYAL REDENSITY I CARDIFF
NOURISH. REDENSIFY. ILLUMINATE.
The only injectable skin booster that delivers 14 bioactive nutrients directly into the dermis — not just hydration, but genuine skin nutrition from within.
By Teoxane Switzerland. Available at Sebastian-Rose Medical Aesthetics Cardiff.
TEOSYAL REDENSITY I - BY TEOXANE SWITZERLAND - 14 BIOACTIVE NUTRIENTS IN EVERY INJECTION
Teosyal Redensity I by Teoxane Switzerland is not simply a skin booster. It is the only injectable on the market that combines pure hyaluronic acid with a patented cocktail of 14 bioactive nutrients — amino acids, antioxidants, minerals and vitamin B6 — all naturally present in healthy, youthful skin but lost through ageing, environmental damage and stress. Where standard skin boosters add moisture, Teosyal Redensity I restores genuine skin health from within — redensifying the dermis, neutralising oxidative stress and triggering your skin's own collagen and elastin production simultaneously. The result is skin that is visibly brighter, firmer and more luminous — because it has been given back exactly what it needs.

WHAT IS TEOSYAL REDENSITY I?
Teosyal Redensity I is not simply a skin booster. It is a bioactive skin nutrient infusion — a Swiss-engineered injectable that goes further than any standard hyaluronic acid treatment by combining pure hyaluronic acid with a patented cocktail of 14 bioactive ingredients that are naturally present in healthy, youthful skin.
Developed by Teoxane Laboratories in Geneva — one of the world's leading authorities in hyaluronic acid science — Teosyal Redensity I uses the brand's proprietary RHA (Resilient Hyaluronic Acid) technology to deliver not just hydration but genuine dermal nutrition. It replenishes the essential building blocks that the skin loses with age, environmental damage and stress — amino acids, antioxidants, minerals and vitamins — directly into the layer of skin where they are needed most.
The result is skin that looks and genuinely is healthier. More radiant. More evenly textured. More luminous. Not because anything has been added on top, but because the skin has been given back what it needs to function as younger, healthier skin does.
At Sebastian-Rose Medical Aesthetics Cardiff, we offer Teosyal Redensity I as part of our comprehensive skin quality programme — used as a standalone treatment, as part of a course, or in combination with other regenerative treatments for advanced skin renewal.
WHAT MAKES TEOSYAL REDENSITY I DIFFERENT?
Most injectable skin boosters deliver hyaluronic acid. Teosyal Redensity I delivers hyaluronic acid plus 14 additional bioactive ingredients — a distinction that matters enormously in terms of what the treatment actually does to the skin.
The 14 bioactive ingredients in Teosyal Redensity I include eight essential amino acids (arginine, glycine, lysine, threonine, proline, isoleucine, leucine and valine), three antioxidants (glutathione, N-acetyl-L-cysteine and alpha lipoic acid), two minerals (zinc and copper) and vitamin B6 — all of which are essential for healthy skin cell function, collagen synthesis and protection against oxidative stress.
Oxidative stress — caused by UV exposure, pollution, stress and ageing — is one of the primary drivers of skin deterioration. Most skin boosters do not address it. Teosyal Redensity I specifically targets it, making it one of the most clinically comprehensive injectable skin treatments available.
This combination treats not just dehydration but the underlying biological reasons why skin loses its quality, density and luminosity over time.
WHAT DOES TEOSYAL REDENSITY I TREAT?
Skin Dullness and Loss of Radiance
One of the most immediate and visible effects of Teosyal Redensity I is a restoration of luminosity — the skin glow that is often the first thing to go with age, stress and environmental exposure. Many clients notice brighter, more radiant skin even after their first session.
Dehydration and Loss of Skin Density
As we age, we lose up to two thirds of our natural hyaluronic acid pool — the substance responsible for keeping skin plump, hydrated and resilient. Teosyal Redensity I replenishes this pool from within, at a depth no topical product can reach.
Fine Lines and Skin Texture
By stimulating collagen and elastin production and deeply hydrating the dermis, Redensity I progressively smooths fine lines, improves skin texture and restores a uniformly smoother complexion.
Skin Laxity and Loss of Firmness
The combination of hyaluronic acid and bioactive ingredients works to restructure and redensify the dermis — improving skin tone, tightness and overall firmness progressively over the course of treatment.
Dull, Tired or Stressed-Looking Skin
Whether caused by lifestyle, lack of sleep, hormonal changes or environmental factors, skin that simply looks tired responds exceptionally well to Teosyal Redensity I's nutrient-rich formula.
Sun-Damaged Skin
The antioxidant complex in Teosyal Redensity I specifically targets oxidative stress — one of the primary mechanisms of sun damage — making it an excellent treatment for skin with a history of UV exposure and pigmentation concerns.
Neck and Décolletage
The neck and décolletage are often neglected in aesthetic treatment plans despite showing significant signs of ageing. Teosyal Redensity I is specifically designed for use in these areas as well as the face — providing comprehensive treatment for the most visible skin zones.
Hands
Ageing, crepey skin on the hands responds well to Teosyal Redensity I's hydrating and redensifying action, improving the appearance of thin, textured skin on the backs of the hands.
IS TEOSYAL REDENSIT I A DERMAL FILLER?
No — and this is one of the most common misconceptions we encounter at Sebastian-Rose. Teosyal Redensity I is a skin booster and bioactive skin nutrient, not a volumising dermal filler. Here is the key distinction:
TEOSYAL REDENSITY I Spreads evenly through the superficial dermis after injection. Does not add volume or change facial structure or contour. Delivers 14 bioactive nutrients alongside hyaluronic acid. Improves skin quality, density, hydration and radiance. Results appear progressively over a course of treatment. Lasts 6–12 months depending on lifestyle and skin condition. Ideal for skin quality, nutrition, hydration, radiance and mild laxity.
VOLUMISING DERMAL FILLER Stays localised where injected to add targeted volume. Changes facial contours and structure in specific areas. Contains hyaluronic acid only — no additional bioactive ingredients. Addresses specific structural concerns immediately. Results appear immediately. Lasts 6–18 months. Ideal for targeted volume loss and facial definition.
Many clients at Sebastian-Rose benefit from both — Teosyal Redensity I to improve the quality and health of the skin across the whole face, and targeted Teosyal RHA fillers to address specific structural or volume concerns. Your practitioner will advise on the right combination at your free consultation.

AM I SUITABLE FOR TEOSYAL REDENSITY I?
You may be an ideal candidate for Teosyal Redensity I if:
Your skin looks dull, tired or lacks its former radiance regardless of your skincare routine.
If you have noticed fine lines, loss of skin texture or a general deterioration in skin quality.
If you have dehydrated, crepey or loose skin on the face, neck or décolletage.
If you want to address the effects of sun damage, environmental stress or lifestyle factors on your skin quality.
If you are in good general health and have realistic expectations.
If you are looking for a genuinely preventative treatment — Redensity I is an excellent choice from your mid-twenties onwards to maintain skin health before visible ageing begins.
WHO SHOULD NOT HAVE TEOSYAL REDENSITY I?
Who May Not Be Suitable
Teosyal Redensity I may not be suitable if you are pregnant or breastfeeding, have active skin infections or inflammation in the treatment area, have a known allergy to hyaluronic acid or lidocaine, have blood disorders or are immunocompromised, or have active autoimmune conditions — your practitioner will assess this at consultation.
You cannot have Teosyal Redensity I if you are under the age of 18, pregnant, and / or breast feeding.
A thorough medical consultation is always carried out before any treatment at Sebastian-Rose. We will always tell you honestly if Teosyal Redensity I is or isn't the right treatment for your skin.
HOW DOES TEOSYAL REDENSITY I WORK?
Teosyal Redensity I works through a process of dermal redensification — restoring the dermis to a healthier, more youthful state from within by delivering the precise combination of ingredients that the skin needs but can no longer produce or retain in sufficient quantities.
The hyaluronic acid component attracts and retains moisture within the dermis, immediately improving hydration levels and creating a plumping effect that progressively improves skin density and firmness. The amino acids provide the essential building blocks for collagen and elastin synthesis — giving the skin what it needs to rebuild its structural framework naturally. The antioxidant complex — glutathione, N-acetyl-L-cysteine and alpha lipoic acid — neutralises free radicals and protects the skin from oxidative stress, addressing one of the root causes of accelerated skin ageing. The minerals zinc and copper support essential enzymatic processes within skin cells, and vitamin B6 is essential for skin cell renewal and healthy metabolism.
Together these 14 ingredients work synergistically with the hyaluronic acid — creating a treatment that addresses multiple mechanisms of skin ageing simultaneously rather than simply adding moisture.
WHAT DOES A TEOSYAL REDENSITY I TREATMENT INVOLVE AT SEBASTIAN ROSE?
Your Free Consultation
Every Teosyal Redensity I journey at Sebastian-Rose begins with a complimentary, no-obligation consultation. We will assess your skin quality, discuss your concerns and goals, and determine whether Redensity I — or a combination of skin treatments — is most appropriate for you.
Your Treatment Plan
The recommended initial course is 3 sessions, spaced 3 weeks apart — in line with Teoxane's clinical guidelines. A 4th maintenance session within the first year is recommended to sustain and build on results. Following your initial course, maintenance sessions every 6–9 months keep the skin consistently at its best.
The Treatment
Teosyal Redensity I is administered using a series of microinjections into the superficial dermis using extremely fine needles. The product contains lidocaine — a local anaesthetic — for comfort during treatment, and topical numbing cream is available. Treatment sessions typically take 20–30 minutes. The entire face, neck and décolletage can be treated in a single session if required.
After Your Treatment
You may experience mild redness and small injection site marks for up to 24 hours following treatment — this is completely normal. Most clients feel comfortable returning to their normal activities immediately. Makeup can usually be applied the following day.
Aftercare Guidelines
Avoid strenuous exercise for 24 hours. Avoid hot baths, saunas or steam rooms for 48 hours. Avoid excessive sun exposure and apply a high-factor SPF daily. Avoid other skin treatments including chemical peels for 2 weeks. Do not massage the treated area. Stay well-hydrated — water supports the hyaluronic acid in working optimally.
TEOSYAL REDENSITY I RESULTS - WHAT TO EXPECT
After Session 1
Many clients notice an immediate improvement in skin radiance and hydration following their first Teosyal Redensity I session — a brightness and freshness to the skin that is often visible within 24–48 hours. Mild redness and injection site marks resolve quickly.
After Session 2
Weeks 3–6
The progressive bio-stimulation of collagen and elastin becomes increasingly visible. Skin texture improves, fine lines soften and skin feels noticeably firmer and more elastic. The cumulative nutrient infusion is building the skin's internal health progressively.
After Session 3
Weeks 6–9
Full results of the initial course become visible. Skin is markedly more radiant, hydrated, firm and evenly textured. The antioxidant protection is active and the skin's capacity to retain moisture has been genuinely restored.
Months 3–6
Results are maintained and continue to mature as collagen and elastin production builds cumulatively. Many clients describe this stage as their skin simply looking its best — healthy, luminous and genuinely well rather than obviously treated.
Maintenance
Results typically last 6–12 months depending on lifestyle, sun exposure and skin condition. A maintenance session every 6–9 months sustains results long-term. Clients who maintain regular Teosyal Redensity I treatments report cumulative improvement in skin quality year on year.

TEOSYAL REDENSITY I FAQ'S
How long does Teosyal Redensity I last?
Results from a full course of Teosyal Redensity I typically last 6–12 months, depending on your age, lifestyle, sun exposure and individual skin condition. Maintenance sessions every 6–9 months sustain results and build cumulatively over time.
How many sessions of Teosyal Redensity I will I need?
The recommended initial course is 3 sessions spaced 3 weeks apart, with a 4th maintenance session recommended within the first year. After your initial course, a single maintenance session every 6–9 months is typically sufficient to maintain results.
Does Teosyal Redensity I hurt?
Teosyal Redensity I contains lidocaine — a local anaesthetic — which significantly reduces discomfort during treatment. Topical numbing cream is also available. Most clients describe the sensation as mild stinging at injection sites that resolves quickly. The treatment is generally very well tolerated.
Is there downtime after Teosyal Redensity I?
There is minimal downtime. You may experience mild redness and small injection site marks for up to 24 hours. The majority of clients return to normal activities — including work — immediately after treatment. Makeup can be applied the following day.
When will I see Teosyal Redensity I results?
Many clients notice an immediate improvement in skin brightness and hydration following their first session. Progressive improvements in texture, firmness and overall skin quality develop over the following weeks as collagen stimulation builds. Full results of the initial course are typically visible 2–4 weeks after the third session.
What are the 14 bioactive ingredients in Teosyal Redensity I?
Teosyal Redensity I contains 8 amino acids (arginine, glycine, lysine, threonine, proline, isoleucine, leucine and valine), 3 antioxidants (glutathione, N-acetyl-L-cysteine and alpha lipoic acid), 2 minerals (zinc and copper) and vitamin B6. These are all naturally present in healthy skin and work synergistically with the hyaluronic acid to restore skin health from within.
Can Teosyal Redensity I be used on the neck and décolletage?
Yes — Teosyal Redensity I is specifically designed and recommended for use on the face, neck and décolletage. It is one of the few injectable skin treatments that treats all three zones comprehensively in a single session.
Can Teosyal Redensity I be combined with other treatments?
Yes — Teosyal Redensity I combines excellently with Botox, dermal fillers, Profhilo, Sculptra, polynucleotides and microneedling. At Sebastian-Rose we frequently design bespoke combination skin treatment programmes. Your practitioner will advise on the most appropriate combinations at consultation.
How does Teosyal Redensity I compare to Profhilo?
Both are injectable skin quality treatments using hyaluronic acid, but they work differently. Profhilo uses IBSA's NAHYCO technology with a very high concentration of pure HA to bio-remodel the skin and stimulate collagen and elastin. Teosyal Redensity I combines a lower concentration of HA with 14 additional bioactive nutrients to address skin nutrition and oxidative stress as well as hydration. Profhilo tends to deliver stronger bio-remodelling and structural collagen stimulation — Redensity I delivers a more comprehensive nutrient infusion that addresses the broader biological causes of skin ageing. Many clients benefit from both as a combined programme.
How does Teosyal Redensity I compare to Juvelook?
Juvelook is a Korean injectable combining hyaluronic acid with PDLLA microspheres for dual-action hydration and collagen stimulation. Teosyal Redensity I is a Swiss product combining hyaluronic acid with 14 bioactive nutrients for skin redensification and antioxidant protection. Juvelook is particularly strong for collagen stimulation and glass-skin effects — Redensity I is particularly strong for skin nutrition and antioxidant protection. Both are excellent. Your practitioner will recommend the most appropriate option at consultation.
How does Teosyal Redensity I compare to Sculptra?
These treatments work at entirely different levels. Teosyal Redensity I is a superficial dermis treatment focused on skin quality and nutrition. Sculptra is a deep collagen biostimulator focused on facial volume restoration and structural framework. They are complementary rather than competing treatments and many clients at Sebastian-Rose use both as part of a comprehensive regenerative programme.
How does Teosyal Redensity I compare to NCTF?
Both NCTF and Teosyal Redensity I are multi-ingredient skin nutrient injectables. NCTF by Fillmed contains over 50 active ingredients including polynucleotides and HA. Teosyal Redensity I contains 14 precisely selected bioactive ingredients combined with Teoxane's proprietary hyaluronic acid. Both are excellent for skin nutrition — the specific formulation that is right for your skin will be assessed at consultation.
How does Teosyal Redensity I compare to Sunekos?
Sunekos combines hyaluronic acid with a patented amino acid complex that specifically targets extracellular matrix regeneration and elastin production. Teosyal Redensity I uses a broader bioactive formula targeting hydration, nutrition and antioxidant protection. Sunekos tends to be preferred for more significant laxity — Redensity I for comprehensive skin nutrition and luminosity. Both are offered at Sebastian-Rose and your practitioner will advise on the best option for your individual concerns.
Is Teosyal Redensity I suitable for younger skin?
Yes — Teosyal Redensity I is an excellent preventative treatment from the mid-twenties onwards. It is particularly appropriate for younger clients experiencing dullness, dehydration or early signs of skin quality decline, and for those wanting to protect their skin against oxidative stress and environmental damage before visible ageing becomes established.
Is Teosyal Redensity I available on the NHS?
No. Teosyal Redensity I is a cosmetic treatment and is not available on the NHS. It is available privately at Sebastian-Rose Medical Aesthetics Cardiff.
Do you offer Teosyal Redensity I for men?
Absolutely. Teosyal Redensity I is an excellent treatment for male clients seeking improved skin quality, hydration and radiance without any obvious signs of cosmetic treatment. We welcome clients of all genders.
