Efficacy
Efficacy of Hyaluronic Acid Pure Active on Facial Wrinkles
-
Plumps up the skin (low molecular weight)
Deeply stimulates the synthesis of hyaluronic acid and collagen naturally present in the skin to visibly reduce facial wrinkles.
-
Hydrates (high molecular weight)
Protects the skin from dehydration on the surface of the epidermis. Acting like a sponge, it is able to retain up to a thousand times its weight in water.
Is this care suitable
for your skin?
-
When
Our recommendation: use for 8 weeks as a replacement for serum.
-
Where
Apply to the entire face, concentrating on wrinkles. Apply to dry, thoroughly cleansed skin.
-
How
Squeeze the base of the bottle and apply 4 drops directly to facial skin.
Do not use more than 2 pure active ingredients at a time. When using 2 active ingredients, you may apply one after the other.
Remember to apply Hyaluronic Acid Pure Active last, just before using your moisturiser (it forms a light film on the skin).
The efficacy of this highly purified and perfectly dosed active ingredient is scientifically proven to help diminish wrinkles and fine lines.
We have added additional ingredients to this active: their exclusive role is to ensure the product’s stability and ability to penetrate the skin (In-Skin patent). Nothing more, nothing less.
Obtained through the natural fermentation of plant substrates (wheat and beetroot).

How do I know if I have established wrinkles?
Established wrinkles appear with age, particularly due to dehydration, a loss of elasticity, reduced collagen production, and natural skin slackening. These wrinkles can be seen on a number of areas on the face: the nasolabial folds (from the nostrils to the corner of the mouth), marionette lines (at the corner of the mouth), the lip contour, the chin, and the neck and décolleté. To combat these established wrinkles and firm skin, the ideal solution is a targeted treatment to plump up the skin and fill in wrinkles.
-
What are dehydration lines?
They appear over time where the skin is thinner and sensitive, most often around the eyes and lips. They are caused by a lack of skin hydration, or external factors such as smoking and pollution.
-
What is high molecular weight hyaluronic acid?
Hyaluronic acid molecules penetrate to different depths in the skin depending on their size, or molecular weight. Molecules with a high weight act on the surface of the epidermis. They form a non-occlusive protective film and can retain up to one thousand times their weight in water. Skin is therefore protected against dehydration and the natural hydrolipidic film is strenghtened to prevent further water loss.
-
What is low molecular weight hyaluronic acid?
Hyaluronic acid molecules penetrate to different depths in the skin depending on their size, or molecular weight. Molecules with a low weight have the ability to penetrate deeper into the skin to stimulate the synthesis of the hyaluronic acid and collagen that are naturally found deep down in the skin, ensuring skin tone and firmness. The skin is plumped up and facial wrinkles are reduced.
-
Is Hyaluronic Acid Pure Active recommended for sensitive skin?
Yes, our hyaluronic acid is formulated to be kind to skin and is tested on sensitive skin. As with all Pure Active products, always ensure you follow our usage instructions (dose, duration) on the product page.
-
Pure Active: how is this different from a serum?
In terms of the way it is used, Pure Actives are applied like a serum: to clean skin before your face cream, to provide a specific action.
But, unlike a serum, our Pure Actives only contain a single, perfectly dosed, active molecule, which precisely targets a skin issue. This means that they are ultra-safe, since there’s no risk of a cocktail effect (piling up different active ingredients). And our INSkin™ patent helps it to penetrate down to where it needs to be in the skin. -
Pure Active: should I apply it before or after my face cream?
Always before your moisturising cream, but most importantly, always on clean skin. Thanks to their drop-by-drop bottles, Pure Actives are applied in small quantities, where they are needed (see the detailed instructions for each product).
-
What is the maximum number of Pure Actives that I can apply to my skin?
We recommend applying no more than 2 Pure Actives at once to your face (1 Pure Active after the other, to clean skin before applying your face cream). In most cases, the best solution is to treat one problem at a time with a Pure Active. If you apply multiple active substances on your skin there is a risk of over-treating it.
-
How long should a Pure Active be used for?
Pure Actives should be used like a “course of treatment”, for between 3 and 8 weeks depending on the active ingredient and the benefit in question. That’s why we package them in small anti-UV containers suited to short-term use. To ensure they stay effective, you should store them away from heat and light, and for no more than 6 months. You’ll find usage instructions for each Pure Active on the product pages on the site.
-
What is the difference between Pure Skincare and Pure Actives?
Pure Skincare products do not contain any active ingredients, to take care of skin every day, without needlessly irritating it. Pure Actives offer a targeted action to treat skin problems when necessary (1 Pure Active = 1 skin issue). Healthy skin with no particular issues does not need Pure Actives.
-
Do your products contain fragrances?
Our Pure Actives do not contain fragrances, nor do some of the other care products such as the Moisturising Eye Contour Fluid, the Melting Exfoliating Gel and the Express Purifying Mask. The majority of our Pure Skincare products are very lightly scented to make them pleasant to use while being kind to skin. We carefully select our fragrances, which we create ourselves, and make sure they are free from allergens and sensitising substances.
-
Are your products tested on animals?
No, in accordance with the applicable European cosmetics regulations, our products and the ingredients they contain are not tested on animals. Toxicology experts have evaluated our formulas’ perfect tolerance. And, of course, our products are tested under dermatological and ophthalmological supervision if necessary.
-
Do your products contain preservatives?
In order to protect our formulas from contamination, we use the necessary amount of natural preservatives (black radish extract, potassium sorbate or capryloyl glycine). We also use airless bottles, pumps and tubes to limit the risk of contamination, and therefore the quantity of preservatives.
