What is "Rubus Idaeus Fruit Extract" and what is its utility?
A few words on the red raspberry.
The Rubus idaeus is the scientific name for the red raspberry bush. This shrub, belonging to the Rosaceae family, originates from Europe and Asia (from Turkey to Siberia, passing through China and Japan). It thrives in regions with a cold climate. The species name of the raspberry bush, "Idaeus", comes from its discovery on Mount Ida near Troy in northern Turkey, a setting of Greek mythology. According to legend, the fruit derives its red colour from the blood of Ida, the daughter of the King of Crete and nurse of Zeus. In an attempt to soothe him, she supposedly picked raspberries, which were originally white in colour, and scratched her breast, which bled and stained the fruits red.
Today, the raspberry is a fruit widely used in cooking. In skin and hair care, it can be incorporated into formulas in the form ofvegetable oil (Rubus Idaeus Seed Oil), powder (Rubus Idaeus Seed Powder) and/oraromatic extract (Rubus Idaeus Fruit Extract).
How is the plant extract of raspberry obtained?
Raspberry extract is derived from the soaking of the fruits in a circulating mixture of bioglycerin-water. Organoleptically, the raspberry plant extract is a reddish to brown liquid with a fruity smell. It is soluble in water and alcohol but insoluble in any lipophilic environment. Its incorporation rate in a cosmetic formula is not regulated, but it is recommended by the main suppliers of this extract at a content between 0.3 and 10%.
What are the benefits of Rubus Idaeus Fruit Extract?
Thanks to its antioxidant action, raspberry extract is used to slow down the appearance of ageing signs induced by oxidative stress. Indeed, the compounds it contains such as polyphenols and vitamin E act at the internal structure of the skin. They notably help to counteract the effects of oxidation reactions, which are responsible for the deterioration of the body's constituents such as collagen and elastin. As a reminder, these fibrous proteins present in the dermis are responsible for the skin's tone and elasticity.
The plant extract of raspberry also exerts this antioxidant action when applied to hair. It thus protects the hair from external aggressions (pollution, sun, cigarette smoke...) that generate an overproduction of free radicals. Oxidative stress is a factor linked to the deterioration of hair fibres, the appearance of white hair, or even hair loss. The raspberry extract and the molecules it contains neutralise these free radicals to prevent them from causing damage and maintain good hair quality for as long as possible.
Beyond its antioxidant activity, raspberry extract also has exfoliating and purifying properties. It removes dead cells from the skin's surface for an immediate radiance boost. It reveals smoother skin and a refined skin texture.
Furthermore, the presence of minerals (potassium) acts on inflammations, helping to soothe redness and irritation.
