Cosmetic tests: the scientific requirement by FILORGA.

The quality and effectiveness of a cosmetic product depend primarily on the active ingredients that make it up. Active ingredients are those that act on the surface and in the different layers of the skin. Some of them like hyaluronic acid, collagen, or antioxidants, are probably already familiar to you.

To create a skin care product, FILORGA selects the active ingredients according to very precise specifications: the effectiveness and safety of each ingredient must be proven by science and its quality must be irreproachable. The search for the right ingredient, a step called sourcing, is therefore essential in the development process of a product.

But creating an anti-wrinkle cream or moisturizing serum is not just a matter of mixing. Like star chefs, the experts at Laboratoires FILORGA know better than anyone how to combine these quality active ingredients at concentrations whose effectiveness has been scientifically proven and which will allow them to shine. They also know how to determine, thanks to their decades of experience, the ideal quantity of each ingredient and integrate them into effective and comfortable formulas.

Before being put on the market, each FILORGA skin care product undergoes numerous tests and European cosmetic regulations require us to prove all the benefits that we put forward for each product. Simply put, if we can’t prove it, we have no right to assert it.

In addition, because we are confident in our manufacturing processes and know-how, we place high demands on ourselves in terms of efficiency. Thus, if a day cream does not give results after 7 days of use, we do not market it.

Tests carried out in the laboratory.

Our scientific team carries out two types of tests to study the mechanism of action of our products, such as the increase of collagen in the skin.

In vitro tests (Latin for “under glass”) are used to observe the effectiveness of an active ingredient or care product on the skin cells. 

Ex vivo tests (Latin for “outside the living”) are performed on portions of human skin (from voluntary donors, after surgery). Compared to in vitro tests, ex vivo tests provide a more accurate view of the effect of the skin care product under real application conditions, compared to untreated skin.

Clinical study.

This type of cosmetic test is performed in vivo (from the Latin “in the living”), on women volunteers to test the product. They follow the protocol provided by us for 1 to 8 weeks. This protocol is managed by an independent laboratory: it is validated beforehand by dermatologists who are also responsible for evaluating the results.

Before and after the application of the product, they observe the evolution of skin parameters such as hydration rate, wrinkle depth, skin tone, skin luminosity, etc. The independent evaluator then records their analysis based on instrumental measurements and/or an approved medical scale.

The self-evaluation questionnaire.

The last cosmetic test we practice is self-evaluation. Participants are asked to complete a satisfaction questionnaire to assess the effectiveness of the product at different time points during the study (immediately after product use, after 7 days, after 28 days, etc.). 

These self-assessments reflect the impressions of testers, “real life” people, after using the products.

Our objective with these cosmetic tests is not only to evaluate our products before they are put on the market. We also communicate our results in international dermatology and aesthetic medicine congresses as well as in scientific journals, in order to advance research.

To illustrate our testing process, we will give you a few examples of the tests performed during the development of our anti-wrinkle cream TIME-FILLER 5XP.

In the laboratory.

For our ex vivo test, we used skin explants donated by a 60-year-old woman.

After 6 days of daily application of TIME-FILLER 5XP, our scientists observed a significant increase in the components of the dermis that help fill in and reduce wrinkles.

Compared to untreated skin, this resulted in:

• +25% elastin*
• +59% collagen*
• +34% hyaluronic acid*

*Ex vivo test on human skin explant. Histochemical analysis after 6 days of daily application of TIME-FILLER 5XP gel-cream. p<0.05 compared to untreated skin.

These results tend to show that TIME-FILLER 5XP can have a positive effect on wrinkle reduction.

Clinical study.

Conducted by an independent laboratory, this study was based on the following protocol:

• 33 volunteers aged 45 to 65 years.
• Skin types: normal to dry, sensitive skin.
• Twice-daily application of the product to the face and neck for 56 days.

After 8 weeks, a significant decrease in the volume of 5 wrinkles of the face and neck was demonstrated.

The self-evaluation questionnaire.

The self-evaluation questionnaire filled out by our volunteers confirmed the effectiveness of our anti-wrinkle cream after only 7 days of application:

• 87%* of women noted that TIME-FILLER 5XP gel-cream had a smoothing effect on their skin. *Clinical study – 30 subjects – after 7 days of twice daily application of TIME-FILLER 5XP gel-cream.

li style=”font-weight: 400;” aria-level=”1″>The organoleptic properties of the products were highly appreciated with a very good satisfaction rate on the penetration, the texture, the smell and the feeling of comfort.

In addition, 9 out of 10 women* said they found their skin younger after 56 days of application. *Clinical study – 29 subjects – after 56 days of twice-daily application of TIME-FILLER 5XP cream.

For over 40 years, FILORGA has developed strong scientific expertise in the field of skin care. The extensive cosmetic tests to which we subject our products make FILORGA a reference in terms of quality, effectiveness and safety of beauty products.
