Is this care suitable
for your skin?

  • When

    Our recommendation: use for 4 consecutive days as an initial treatment to fight dilated pores and restore radiance, then use twice a week for one month.

  • Where

    Apply exclusively to affected facial areas, avoiding the eye contour area. Apply to dry, thoroughly cleansed skin.

  • How

    Squeeze the base of the bottle and apply drops to the tips of the fingers. Gently smooth and press into the skin as follows: - 4 drops to the entire face, - or 1 drop to each area of particular concern (dilated pores, small blemishes).

A slight tingling sensation may be felt upon application: this is completely normal.

We do not recommend combining Salicylic Acid 2% and Citric Acid 26%. Do not use more than 2 pure active ingredients at a time. If you are using 2 active ingredients, you may apply one after the other.

The antioxidant efficacy of this highly purified and perfectly dosed active ingredient is scientifically proven to help improve facial radiance.

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.

  • How can I tell if my pores are enlarged?

    Pores are tiny orifices on the skin from which sweat and oil flow. They can become bigger due to external stress, excess oil flow or insufficient care, often on the sides of the nose and the T-zone. Impurities then have the ability to lodge themselves in the pores and build up until a blackhead appears. Everyone’s pores are more or less dilated and therefore visible, but this issue is more common in men than women, and in oily skin. An easy way to determine if your pores are enlarged is to compare the area of concern with another area of the face. Pores commonly become enlarged in the T-zone (forehead, nose and chin) where there is more oil flow.

  • What constitutes excess sebum?

    Sebum is composed of lipids (oil) and contributes to the face’s skin barrier function. It protects the skin from damage, especially UV-induced oxidation as well as prevents transepidermal water loss. With hyperseborrhoea, or excess sebum, the skin tends to present a shine throughout the day either in the T-zone or over the entire face. Unsuitable or poorly used cosmetics (too rich, too stripping) and sun exposure without protection can encourage excess sebum production. In adulthood, causes include pollution, smoking, stress and fatigue. In teenagers, hormones play a role.

  • What is an AHA?

    An AHA is an alpha-hydroxy acid, usually taken from a fruit (fruit acid) or other natural compounds containing sugar. The most used and well known are citric acid (from lemons), glycolic acid (from sugar cane), lactic acid (from milk) and malic acid (from apples).
    AHAs are “chemical” exfoliants (as opposed to mechanical exfoliants with grains). They help eliminate dead cells from the surface of the skin and therefore stimulate cell renewal for a more even skin texture, and smooth, even and bright skin.

  • 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.
