During
the Antarctic summer of 1988, a Spanish scientific expedition collected
mud samples from the inlet Admiralty Bay, on King George Island, Antarctica.
A new bacterial strain, Pseudoalteromonas Antarctica, was isolated from
these samples and characterized.
During growth, the
bacteria produced an extracellular material, an exopolymer of glycoproteins
believed to help the bacteria retain water, adhere to surfaces, and withstand
the extreme cold.
Its protective function
in nature is applied in cosmetics to regenerate and protect the skin.
- Pseudoalteromonas Ferment Extract
helps the skin retain water
- Pseudoalteromonas Ferment Extract
presents a cryoprotective effect due to its ability to modify the morphology
of ice crystals
- Pseudoalteromonas Ferment Extract
stimulates fibroblast adhesion and keratinocyte growth, regenerating
tissues and enabling a faster healing of wounds
- Pseudoalteromonas Ferment Extract
increases collagen type I and IV, as well as elastin, resulting in a
restructured skin and a reduction in wrinkles
- Pseudoalteromonas
Ferment Extract reduces the depth of expression wrinkles, especially
in the forehead and around the eyes
In nature, Pseudoalteromonas Ferment Extract
has the function of protecting the bacteria against harsh conditions.
In cosmetics, Pseudoalteromonas Ferment Extract maintains its natural bioprotective
properties and promotes keratinocyte growth and fibroblast adhesion for
a skin regenerating effect and enhanced wound healing.
In Vitro Test
An in vitro skin model
composed of keratinocytes and fibroblasts was used to monitor the levels
of Collagen I, Collagen IV and Elastin.
- Collagen
I increases 128% in 15 days
- Collagen
IV increases 81% in 15 days
- Elastin
levels increase 31% IN 15 days
In Vivo test
on volunteers
Skin topography analyses were performed by obtaining silicon imprints
from around the eyes of 10 healthy women volunteers.
The product tested was a cream containing 5% Pseudoalteromonas Ferment Extract and it was applied
twice daily for 30 days.
Silicon imprints were obtained pre-test and after 30 days. Analyses of
the imprints were performed by confocal laser scanning microscopy to assess
the evolution of the skin surface before and after the treatment. Skin
topography images from the three dimensional reconstruction of optical
sections are shown in the figure. The depth of the wrinkle decreased significantly,
with maximum values between 50 and 60%.
