Belonging to the species of Rubus idaeus, the fruits are known for their excellent therapeutic properties being rich in compounds with strong antioxidant activity, promoting health and well-being of human cells. Have you guessed which amazing botanical plant oil I am referring too...? Say hello to Red Raspberry Seed Oil.
Collagen - the lowdown
The Dermis (middle layer) is the main part of the skin and is where blood vessels, lymph vessels, nerve ending, sweat glands, hair ducts and sebaceous glands reside. Collagen is the tough fibre which bundles all this together. Elastin fibres allow for the dermis to be flexible and stretch, the Dermis gives your skin it's firmness. Wrinkles develop here, in the dermis due to the degradation of these two important fibres.
70% of our dry skin mass is comprised of collagen,
the loss of collagen as we age is due to the
slowing down our our ability to produce collagen.
The Dermal Matrix components of collagen and elastin are responsible for the appearance of the skin, collagen is produced and secreted by fibroblasts, together with dermal proteins of the Extracellular Matrix (ECM).
Collagen predominantly consists of Collagen type I and type II and is responsible for the tensile strength, stability of the dermal tissue and blood vessels (your skin). Collagen can be damaged by the suns UVA and UBV rays which stimulate Reactive Oxygen Species (ROS) that in turn synthesis enzyme degenerating metalloproteases (MMPs). These MMPs can breakdown intact collagen along with already damaged collagen fibres leading to the early signs of ageing. The Eastin-degrading enzyme is known as 'elastase', the Collagen-degrading enzyme is known as 'collagenase'.
How can Raspberry Seed Oil Help?
- POTENT ANTIOXIDANTS - Especially high in Tocopherol (Vitamin E) along with Carotenoids (precursors of Vitamin A), acting as important free-radical scavengers helping to reduce skin damage caused by UV radiation and pollution. Antioxidants assist in the revitalisation of dull skin, stimulate cell repair and importantly protect it from further damage!
- ANTI-INFLAMMATORY - High Linoleic acid (omega-6) and alpha-Linolenic acid (omega-3) content. These are essential fatty acids (EFA) playing an important role in the health of your skin and it's normal function. With both emollient and skin conditioning properties they are particularly beneficial for prematurely ageing skin. Read EFA Explained
- POLYPHENOL COMPOUND - Ellagic acid, present in Raspberry seed oil, is a natural antioxidant and has been shown to reduce the destruction of collagen in skin and promote cellular regeneration. (Remember the destruction of Collagen leads to wrinkle formation and sagging skin.) Ellagic acid has been shown to reduce inflammation due to chronic UV exposure which can lead to photoaging.
- PHYTOSTEROLS - If you struggle with dehydrated skin – as so many of us do especially when ageing – the phytosterols in Raspberry Oil help keep skin hydrated by improving it's ability to retain water. Instead of treating dehydration from the outside-in like some moisturizers, this oil works from the inside-out by decreasing the amount of water that your body loses throughout the day.
THE BIOLOGICAL ACTIVITIES - of Raspberries are partially attributed to their high content of and diverse range of phytochemicals:
Flavonoids (anthocyanins, flavonols, and flavanols)
Tannins (proanthocyanidins, ellagitannins, and gallotannins)
Phenolic acids (hydroxybenzoic and hydroxy- cinnamic acid derivatives)
Lignans (compounds that form the building blocks of plant cell walls)
- HIGH LEVELS - Alpha-Linoleic Acid when compared to any other fruit seed oil. This natural acid has strong anti-inflammatory properties that can help with acne, breakouts, eczema as well as psoriasis.
COMPOSITION - of red raspberry seed oil:
54.5% Linoleic Acid
29.1% R-linolenic Acid
12% Oleic acid
4% Saturated Fatty Acids
Thanks to these active compounds, Red Raspberry Seed Oil is an important addition to my Certified Organic Face Serum specifically designed to fight and reduce wrinkle formation.
Until next time...
