Redensity [I] Beauty Booster

Everybody is speaking about hyaluronic acid! But how exactly does it work?

Hyaluronic acid (HA), which is naturally present in our body, performs a fundamental role in keeping the skin in good health. This essential element of the dermis retains water like a sponge so as to maintain its hydration.

Skin Undergoes Changes with the Passage of Time

The main reasons for the ageing of the skin include excess of oxidants (free radicals)* and progressive loss of intrinsic HA.

With age, we can lose up to 2/3 of our hyaluronic acid pool1. At 35 years of age the skin’s thickness has decreased on average by about 22%.2

As it gets thinner, the skin becomes more fragile, dehydrates and its elasticity diminishes.

Just like an apple that dries, skin that is deprived of its sources of hydration will lose its shine with the passage of time.

Young Skin vs Aged Skin

Teosyal Features

An Alternative for Prevention

The hyaluronic acid injections are designed to prevent premature ageing of our skin and to boost the radiance of our face.3

A Compensation for the Skin

The hyaluronic acid injections compensate the natural loss of this substance and stimulate the auto-production of collagen4 to help smooth out wrinkles, enhance skin glow and restore volume.

The efficacy of injectable hyaluronic acid enables us to push ever forward into the future the need for anti-ageing surgery.5

Approximately 80% of facial skin ageing is attributed to UV-exposure.

When & Where Should It Be Used?8

For your personal protocol, ask your practitioner who will recommend the most optimal treatment for your needs.

  • Regularly as core treatment to prevent cutaneous ageing
  • In alternation with or as a complement to other treatments
  • On specific chosen occasions to rehydrate and give
    a new glow to your skin (for example, before/after
    prolonged sun exposure…)

For the face, neck and neckline.

For an optimal result, it is recommended to follow the complete protocol to extend the effects of the treatment and obtain long-lasting results:

  • for an optimum treatment: 3 sessions at 3-week intervals for immediate and cumulative results
  • for a maintenance treatment of the results, as soon as the need is felt: 1 session usually 3 times a year

Questions women have asked us about Redensity [I]


  • A session consists of intra or hypodermic micro-injections given with a fine needle of very small quantities of Redensity [I] along the lines of wrinkles and evenly spread over the surface of the whole face. In this way the Redensity [I]’s HA and nutrients arrive at the heart of the skin.
  • The injection may be «manual», with syringes and needles, but also «electronically assisted» for more comfort (e.g. Teosyal® Pen).
  • A session lasts about 20 minutes.


A very slight lack of comfort and a few small spots may appear at the injection points*. These inconveniences generally disappear quickly after injection.


The results are seen immediately at the first session. The skin has a better colour, is less creased, better hydrated and becomes more supple. Gradually,
from one session to the next, the complexion looks increasingly radiant and the skin becomes firmer.


The micro-injections are shallow and performed with very fine needles. For better comfort throughout the injection session Redensity [I] contains lidocaine which is a local anaesthetic widely used in the world. For enhanced comfort it is possible to apply an anaesthetizing cream before treatment.


Hyaluronic acid is a resorbable molecule, its effects are temporary and depend on several factors: skin type, age, treated area, injection technique… For an optimum result, an initial protocol of 3 sessions and a maintenance session 2-3 times a year are recommended.

Redensity [II] Under Eye Circle Fighter

Win the battle against eye circles


Stress, lifestyle, thin skin, hereditary factors…we are all unique when it comes to under eye circles 1. Arcane Research study conducted in France in February 2011 on 4,402 women aged 18 to 75.

Remove under eye circles

Your eyes are a reflection of your personality

Your eyes express your emotions and feelings.

But when your eyes are shadowed by under eye circles, they lose their sparkle and shine.

These hollow depressions are caused by a loss of volume below the eyes in the area between the lower eyelid and the cheek, often accompanied by a darkening of skin colour.

Under eye circles can give the illusion of tired, dull and aged appearance. As a result, you don’t feel like yourself anymore, and every day you try to conceal them.

Dr. de Kleer can provide a long-lasting solution to treat under eye circles, using injection of a hyaluronic acid gel specifically developed by TEOXANE Laboratories for the delicate eye contour.

Hyaluronic acid: a medical solution to treat under eye circles

Hyaluronic acid is a natural component2 of the skin. It holds in
moisture like a sponge, to keep skin firm, soft and supple.

However, with age, the skin’s hyaluronic acid content
diminishes. The skin loses volume, becomes dry, thin and
fragile. Underneath the skin, other tissues also retract.

As a result, under eye circles become hollow and more visible.

TEOXANE: Experts in hyaluronic acid

For over 10 years, TEOXANE Laboratories have specialised
in designing hyaluronic acid-based injectable products.
Our researchers have developed a biocompatible gel
specifically designed for the delicate under eye area:

Frequently asked questions about under eye treatment using Redensity [II]

What will happen during the treatment?
The medical practitioner will make a precise diagnosis of the area requiring treatment. An injection of the Redensity [II] gel will be administrated with a sterile, single-use syringe. The session will not take long, usually around 20 minutes.

How many treatments will I need?
Immediate results can usually be seen after just one visit. Occasionally, a touch-up injection may be needed within one month after your first session.

Can I go straight back to work after a session?
You may experience some post injection reactions such as minor bruising and/or swelling in the treated area. These reactions do not always occur and are usually mild, short term and correctable.
