Finally, their elongations without rupture are higher than for the films of the prior art. They are therefore longer.
- the film containing the active whose bioavailability is studied, is deposited on the skins during 10 to 20 minutes. After 10 to 20 minutes of contact, the film is removed, the molecules present on the surface of the skin are removed. The layers of the stratum corneum of the skin are then removed and the active present in these layers is extracted and quantified, it corresponds to the content of the active ingredient in the stratum corneum.
- the assay of the active ingredient in the samples is carried out according to a method adapted to the nature of the test asset, such as, for example, by fluorometry, by chromatography, or any other analytical method adapted to the assay of the chosen active ingredient.
- results are expressed as a percentage of active ingredient present in the stratum corneum with respect to the amount of active ingredient deposited on the skin.
- the different formulas of masks of the market allow a low bioavailability of the active ingredient in the stratum corneum. There is, moreover, no variation between the different formulas, which is of mask-cream type, mask fabric + lotion or hydrogel mask.
- the functionality on the skin of different films containing or not different active ingredients, that is to say the performance in terms of cosmetic effectiveness of the films was evaluated on volunteers.
- the cosmetic evaluation of the films concerned the moisturizing or smoothing effect or improving the complexion or lightening / depigmenting or anti-seborrhoeic or anti-aging.
- the effects have also been studied immediately after the application of a single film, or in the long term after a cure of several films.
- the volunteers apply the film on the face or part of the face for 10 to 20 minutes.
- the moisturizing, smoothing, radiance, anti-seborrhea and anti-wrinkle effects were evaluated immediately after a single film to evaluate the immediate effect, and / or in the long term, after the application of 8 films distributed 28 days.
- This study consists of evaluating the immediate moisturizing effect of the film that does not contain or contains an active ingredient. Hydration rate measurements were performed at the forehead using a MoistureMeter-D ® from Delfin Technologies.
- the MoistureMeter D ® generates a high frequency electromagnetic wave that is sent by a probe to the skin.
- the reflected electromagnetic wave is recorded, thereby obtaining a dielectric constant proportional to the water content of the measured tissue.
- the higher the value of this constant the greater the water content of the fabric.
- the probe used to carry out the measurements is the XS5 probe which mainly measures the water content of the epidermis at the effective measurement depth of 0.5mm. 12 to 21 volunteers applied a film for 10 minutes on the face. The measurements were made before and after removal of the film.
- the evaluation of the anti-seborrhea effect is carried out by measuring the level of sebum on the surface of the skin. Measurements of sebum were made at the forehead before and after application of the film. Measurements were made using a MPA 580 ® handset.
- the MPA580 ® allows direct measurement of sebaceous secretion.
- the plastic film contained in a cassette is translucent and matt (type frosted glass). In contact with the sebum, this film becomes transparent according to the amount of scum located on the surface of the skin.
- the Determination of sebum is achieved by introducing the cassette head into the MPA580 ® handset. A cell then analyzes the transparency of the film. The results are displayed in pg of sebum / cm 2 of skin.
- the measurements were made before the application of the film and 10 minutes after the removal of the film.
- the various films were tested by 11 to 21 volunteers with a sebum level greater than 150.
- the evaluation of the smoothing effect was carried out by analysis of the cutaneous microrelief of the crow's feet by projection of fringes, apparatus dedicated to the 3D measurement of the cutaneous relief (Eotech).
- This system includes a measurement sensor combining a bright fringe projector and a high resolution CCD camera connected to an Optocat acquisition software (Eotech).
- a system of repositioning the volunteer's head according to the 3 axes of displacement makes it possible to find the same measurement zone at the different times of the study.
- the effect of the film is measured on a region of interest cut automatically on the original acquisition.
- the microrelief of the skin is studied by the 3D roughness parameter (Sa) which represents the arithmetic average of surface roughness.
- the software used is the OPTOCAT software, EOTECH. A decrease in these different parameters is characteristic of a smoothing of the studied surface.
- This film refines the grain of the skin
- This first study consists of evaluating the immediate effect of the film. 12 to 20 volunteers applied the film for 20 minutes on the face. Measurements were taken before and 30 minutes after the removal of the film.
- the parameter Sa characteristic of the roughness of the skin microrelief is decreased.
- the cutaneous microrelief of the volunteers is smoothed.
- the film brings an instant smoothing and refines the skin texture. b / long-term effect
- This study consists in evaluating the long-term effect of the film. 12 to 20 volunteers made 8 films in 28 days. Each film was applied for 20 minutes on the face. The measurements are made before the first film and the day after the 8th film.
- the parameter Sa characteristic of the roughness of the skin microrelief is decreased by 7.1%. Thanks to the treatment of 8 films, the cutaneous microrelief of volunteers is smoothed in a sustainable way.
- the film smoothes their skin in a lasting way and reduces skin imperfections.
- the evaluation of the radiance of the complexion was carried out blind by two experts previously trained to judge different parameters representative of the radiance of the complexion.
- the radiance of the skin is characteristic of a radiant complexion. The higher the intensity of the light hooks on the prominent areas of the face, the brighter the skin is.
- the light pink color characterizes a radiant complexion. The more the complexion is pink, the more it is perceived as fresh.
- this parameter is representative of the good-looking effect, if the olive color decreases the good-looking effect is more important.
- This film brings a sparkle
- This first study consists in evaluating the immediate effect of the film with or without active principle. 15 to 20 volunteers applied the film for 20 minutes on the face. Measurements were taken before and 30 minutes after the removal of the film.
- the film improves the good-looking effect and radiation of the skin of the volunteers.
- the film brings an immediate boost and revives the radiance of the complexion.
- This study consists in evaluating the long-term effect of the film. 15 to 20 volunteers made 8 films in 28 days. Each film was applied for 20 minutes on the face. The measurements are taken before the first film and the next day the 8th film. The results are as follows:
- the cure of 8 films has improved the good-looking effect, the radiant complexion and decrease the dull complexion of the skin of the volunteers.
- the 8-film cure brings a permanent glow to their skin and 94% of the volunteers indicate that the cure of 8 films makes their skin more homogeneous.
- Evaluation of the immediate anti-wrinkle effect was performed by analyzing the depth of the main wrinkle at the crow's feet. Standardized facial photographs were made under reproducible lighting conditions using a VISIA-CR (Canfield) system. The visualization of the initial images at the different measurement times as well as the use of a tracking film makes it possible to ensure the good repositioning of the subjects at the different times of the study.

- the evaluation of crow's feet wrinkles was carried out according to the following recommendations: evaluation of the depth of the main wrinkle, not taking into account the number of wrinkles, not taking into account the width of the wrinkles, not taking into account account for any scars.
- the volunteers had to evaluate the stage of wrinkles of their crow's feet by observing themselves in a mirror according to the scale above. This evaluation was done before and after the film was made.
- the study consists in evaluating the immediate effect of the film for its immediate anti-wrinkle effect. 12 to 20 volunteers applied the film for 20 minutes on the face. Self-evaluations were done before and 30 minutes after the film was removed.
- the volunteers also say that the film makes the skin smoother, more hydrated, softer for 92% of the volunteers.
- the film lifts for 75% of the volunteers.
- the film reduces wrinkles around the eye and fades wrinkles and fine lines.
