Lightener

Acts on the skin’s natural pigmentation mechanisms to safely lighten skin.

Lightening the skin is a societal phenomenon and standard of beauty for certain people, whether for cultural or social reasons. Yet most whitening products are dangerous. In fact, they often contain cortisone or corticoids that modify melanin and can cause various problems in the long term (hormonal issues, scarring, burns, etc.). Luckily, some products block the natural pigmentation process without causing harm. In fact, this process is quite easy to understand. First, under the effect of UV rays, the skin releases a hormone, which induces the melanocytes to synthesise melanin in the melanosomes. Melanin is responsible for skin pigmentation and melanosomes are vesicles for the storage and transport of melanin. Melanosomes are subsequently transferred to the epidermis, where they are broken down and eliminated. The melanin released in the process is destroyed more or less swiftly depending on each person’s background. Reducing the number and size of melanosomes is one way to interfere with the natural pigmentation process. Next, melanin synthesis can be reduced. Finally, the transport of melanin to the keratinocytes can be prevented.

[Blᵃ]+HOLLYHOCK, RICE AND LICORICE EXTRACTS

ORIGINS

These three unique plants are well known to naturally brightens and illuminates the face.

EFFICIENCY

In-Vitro :
> 88% inhibition of tyrosinase activity, an enzyme involved in melanin synthesis
> Inhibition of melanocyte differentiation and proliferation

In-Vivo :
> 273% increase in luminosity index after 28 days of application
> 10.1% increase in skin color index after 56 days of application (the higher the index, the lighter the skin)
> 12.58% reduction in the appearance of spots after 56 days of application
> 53% reduction in the amount of melanin contained in pigmentation spots after 56 days of application

[Blᵇ]+PEA EXTRACT

ORIGINS

This synergistic complex of botanical origin is composed of a pea extract and a fatty acid to which is attached a sugar, sucrose dilaurate.

EFFICIENCY

In Vitro:
> 35% decrease in tyrosinase activity (enzyme involved in melanin synthesis)
> 20% decrease in the expression of genes involved in the maturation of melanocytes
> Reduction in melanin formation, determined at the level of released and intracellular melanins.

In Vivo:
> 8% increase in skin lightening after 6 weeks, i.e. a whitening activity similar to hydroquinone (Hydroquinone: reference molecule for its whitening properties but can be irritating).

[Blᶜ]+NARCISSUS POETICUS STEM CELLS

ORIGINS

The narcissus of the poets is a perennial European white flower, with early flowering, heady perfume, cousin of the daffodil, which is known since antiquity for its medicinal properties.

EFFICIENCY

In-Vitro
> 27% decrease in tyrosine synthesis (melanin precursor)
> 18% decrease in tyrosinase activity (enzyme involved in melanin synthesis)
> 17% decrease in the concentration of melanin in keratinocytes by reducing melanosome migration.

In-Vivo
> Color contrast between spots and adjacent skin decreased by 11% > Spots became lighter
> Spots lighten by 10% (measurement of melanin level)
> Adjacent skin areas lightened by 14% (melanin level measurement)
> 10% increase in lightening in the intensity of the spots
> 90% of women say their skin tone is lighter
> 85% of women say their skin tone is more even
> 85% of women report that their pigmentary imperfections have decreased
