Wrinkles and Fine Lines reduction

Skin surface (i.e. wrinkle depth, volume, skin roughness, etc.) is quantitatively assessed by Primos CR SF (Canfield Scientific Europe, BV, Utrecht, Netherlands). Primos CR SF is a non-contact in vivo skin measurement device based on structured light projection. In conjunction with a comprehensive 3-D measurement and evaluation software, the sensor allows to evaluate skin surface properties.

In this study:

- Sa parameter (related to skin smoothness) is measured in the crow’s feet area at T0/T4/T8

- Crow’s feet wrinkle depth is measured at T0/T1h/T4/T8.

Skin profilometry by means of Primos CR SF analysis:




a - The technique.

Primos CR SF (small field) is a 3D scanner that create a point cloud (set of vertices in a three-dimensional coordinate system) of geometric samples on the surface of the subject. These points are then used to extrapolate the shape of the subject (a process called reconstruction). Like cameras, 3D-scanner has a cone-like field of view, and like cameras, they can only collect information about surfaces that are not obscured. While a camera collects color information about surfaces within its field of view, 3D scanners collect distance information about surfaces within its field of view. The “picture” produced by a 3D scanner describes the distance to a surface at each point in the picture (see the image in the insert).

b - Calculation of wrinkle depth.

It is calculated the height of wrinkles in the sampling lengths: this calculation is done on the sectional picture (wrinkle depth vs. section).

c - Calculation of skin smoothness (Sa parameter).

The surface roughness is calculated through the arithmetic roughness (Sa parameter). Sa is the arithmetic mean of the surface roughness and it is a vertical parameter. This means it describes the roughness in vertical direction. The parameter is used to evaluate the surface smoothness.


Skin radiance improvement

Skin radiance (or skin brightness) is the ability of the skin to reflect the light and it is measured using the gloss parameter (taken using the spectrophotometer/colorimeter CM-700D (Konica-Minolta). The instrument emits diffuse light that reaches the skin through an opening located at the extreme of the lighting sphere. A sensor located at 8° compared to the vertical axis of the opening detects then the reflected light and calculates a parameter known as ‘gloss’. The gloss value is used in the management of the brilliance of the colour. Skin radiance is measured at T0/T1h/T4/T8.


Skin moisturisation improvement

Skin moisturisation (and hydration) is evaluated by means of Corneometer® measurement. This measurement is based on the completely different dielectric constant of water (81) and other substances (mostly < 7). The measuring capacitor shows changes of capacitance according to the moisture content of the skin. A metallic lamina separates the metallic tracks (gold) in the probe head from the skin in order to prevent current conduction in the measured area. An electric field between the tracks with alternating attraction develops. One track builds up a surplus of electrons (minus charge) the other a lack of electrons (plus charge). The scatterfield penetrates the very first layer of the skin (10-20 μm) during the measurement and the capacitance is determined.

Skin moisturisation is measured at T0/T1h/T4/T8.


Skin elasticity and firmness improvement

Skin elasticity measurement is based on the suction/elongation method and the subsequent release of the skin inside the opening of the instrument (Cutometer®MPA 580, Courage+Khazaka, electronic GmbH). During the suction/elongation phase the instrument generates, in fact, a constant negative pressure (450 mbar) able to aspirate the skin inside the measurement probe. The suction phase is followed by the release phase, in which the pressure inside the probe is switched to 0 mbar allowing the skin recovery after the elongation phase. An optical measurement system evaluates the depth of the skin inside the probe in the two phases of the measurement, the obtained data are then elaborated and showed graphically and numerically in order to calculate the viscoelastic properties of the skin.

In this study, the following parameter are measured:

- R2 parameter (gross elasticity or overall elasticity): it is the ratio between the residual deformation and the maximum elongation of the skin (Ua/Uf) and it indicates the ability of the skin to return to its original state of recovery after a stressing event. Closer the value is to 1, more elastic is the skin.

- R0 parameter (skin distensibility): it is the first max amplitude of the curve (Uf) and it represents the passive behavior of the skin to a force (i.e. gravity). A reduction of R0 parameter indicates an improvement of the skin ability to oppose to the deformation imposed by the probe during the suction phase, than can be expressed as an improvement of skin firmness.

Skin elasticity and firmness is measured at T0/T4/T8.


Skin barrier function improvement

Skin barrier function is measured at T0/T4/T8 using a Tewameter® TM 300 (Courage+Khazaka, electronic GmbH). The following equation which represents the Diffusion law (discovered by Adolf Fick in 1855) is the basis for the measurement:


A=surface in m² / water transported (in g) - / time (h) - / diffusion constant (=0.0877 g/mhmm Hg) / vapor pressure of the atmosphere (mm Hg) - / distance from skin surface to point of measurement (m)

The diffusion flow dm/dt indicates the mass per cm² which is transported in a specific period of time. It is proportional to the area A and the change of concentration per distance (dp/dx). D is the diffusion coefficient of water vapor in the air. This law is only valid within a homogenous diffusion zone, which is approximately formed by a hollow cylinder. The resulting density gradient is measured indirectly by two pairs of sensors (temperature and relative humidity) and is analyzed by a microprocessor. The measuring head of the probe is a narrow hollow cylinder (10 mm diameter and 20 mm height), in order to minimize influences of air turbulence inside the probe.


Skin sebum reduction

The sebum measurement is based on the internationally recognized Sebumeter® method (Sebumeter 815, Courage+Khazaka GmbH). The measurement principle is the photometric method, the grease spot photometer. According to this method the sebum on skin is collected on a 64 mm2 mat synthetic tape contained in a cassette, then the measuring head of the cassette is inserted into the aperture of the device, where a photocell measures the transparency. The light transmission represents the sebum content on the surface of the measuring area. A microprocessor calculates the result, which is shown on the display in µg sebum/cm² of the skin.

Skin sebum is measured at T0/T4/T8.


Skin impurities removal

On pictures acquired by Visia®-CR (Canfield Scientific) an image analysis with a dedicated software is carried out in order to evaluate Protoporphyrin distribution. Protoporphyrin is produced by bacteria and a decrease of its distribution can be related to impurities removal.

Protoporphyrin distribution is measured at T0/T4/T8.

Protoporphyrin distribution over the face:


Skin pores reduction

On pictures acquired by Visia®-CR (Canfield Scientific) an image analysis with a dedicated software is carried out in order to evaluate pore dimension (size). For each volunteer, the measurement is carried out in a standardized area of the face.

Pore dimension measured at T0/T4/T8.


Skin microbiome improvement

The skin microbiome analysis is based on the metagenomic analysis of the 16S rRNA gene. 16S rRNA gene was chosen since this gene is present in all bacterial (prokaryotic) cells genetic material, but not in human (eukaryotic) cells. Skin microbiota is collected by brushing a defined skin area with a swab, a non-invasive method allowing to collect the bacteria on the skin surface. The second step of the analysis pipeline consists in isolating the bacterial DNA from other components of the sample (human DNA, sebum, dead skin cells, atmospheric pollutants, etc.). Through a series of cell lysis and extraction steps, the purified bacterial material of a given volunteer is obtained. The bacterial material in each sample is then amplified by PCR in order first to increase the quantity of DNA, and second to label the genetic material in each sample - which will later allow the identification of each sample during the sequencing step. The samples’ concentrations are levelled out prior to pooling, to give the sequencing mix. This solution is then loaded in a cartridge and analysed by a sequencer. At the end of the metagenomic analysis run, the raw files are analysed by means of various dedicated software, and the results compiled according to the client’s requirements.

Analysis performed at T0/T8.

Benefit measurement protocol

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum

Where does it come from?

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.
