How Is Rosa Alba Leaf Cell Extract Obtained?

Among the different species and varieties of roses, there is the white rose, or alba rose. The stem cells extracted from this plant promote the oxygenation of skin cells and fight against the overproduction of free radicals. They even out the complexion, revive the skin's radiance and reduce pigmentation defects.

The White Rose: Overview.

The white or alba rose (Rosa alba) is a hybrid species belonging to the large family of Rosaceae. It is native to temperate and subtropical regions of the Northern Hemisphere. There are about 200 species of roses including shrubs and bushes. These hardy plants do not require any particular protection during the winter period. They can easily withstand temperatures as low as -20 °C.

Because of its colorlessness and simple petal crown, the white rose has symbolized purity and innocence since ancient Greek times, when it was the flower of Aphrodite, the young goddess of beauty. Today, this ancient rose is cultivated in some European countries, including France, for its resistance to cold, its sweet and powerful fragrance, and for its essential oil; however, it is said to still grow wild in Asia Minor.

Alba Rose Stem Cells: Definition and Process of Obtaining.

White rose stem cells are whole cells taken from a certain plant part. They are the result of a biotechnological process that respects the environment and biodiversity, which involves several steps:

  1. Selection of the plant and sampling: Removal of a piece of the plant (leaves);

  2. In vitro culture of the sampled plant: Successive replications on a new nutritive medium made of water, minerals, sugar and vitamins;

  3. Elicitation: Stimulation by UV and visible light of the cell culture to produce metabolites (active molecules);

  4. Rinsing: Removal of all traces of the nutritive medium;

  5. Cell filtration;

  6. Sonication of the cells and dispersion of the extract in sunflower oil.

This method of extraction allows keeping all the active molecules present in the plant cells, which confers to this compound a complementary action compared to other vegetable extracts (vegetable oils, essential oils and hydrolats).

Cell Extract of Alba Rose: Benefits for the Skin.

Alba rose stem cells act at different levels to revive the radiance of the complexion:

  1. First, the native rose cells stimulate cell regeneration. As a reminder, this process is essential because it allows the elimination of dead cells and reinforces the skin barrier, thanks to the keratin that keratinocytes are responsible for. A new skin brings radiance and luminosity to the complexion.

  2. Then, they reduce the inflammations related to the aggressions, in particular those of the UVB. They act by inhibiting the activity of three inflammation mediators synthesized at the level of the hair bulb: two cytokines (IL1-alpha and IL-6) and a prostaglandin (PGE2), involved in particular in vasodilation.

  3. Finally, the stem cells of rose provide antioxidant benefits. Indeed, they reduce the creation of free radicals that are due to pollution. Rose cell extract limits the release of malondialdehyde (MDA) during lipid peroxidation induced by pollutant residues and heavy metals. MDA, naturally present in tissues, is a manifestation of oxidative stress. It is derived in particular from the action of reactive oxygen derivatives on polyunsaturated fatty acids.

Due to their actions on the skin, approximately 375,000 native white rose cells are present in our botanical radiance blend. This night serum is best used in the evening, before bedtime, for a luminous skin in the morning. Please note that it is not recommended for pregnant or breastfeeding women due to the presence of essential oil.
