Post menopausal Skin & The Effects of Cosmetic & Culinary Argan Oil
Research discovers the benefits of using Argan Oil for post menopausal skin care.
During menopause decreases in oestrogen hormone production adversely affect the process of collagen and skin fibre production. This can result in decreased skin elasticity – the main sign of aging. Other symptoms can occur such as dry skin, burning sensation, blotchy skin and rashes.
The Berber women of Morocco say that using cosmetic Argan Oil on the skin and eating Culinary Argan Oil helps prevent aging of the skin by maintaining elasticity.
So, researchers at a number of Moroccan Universities undertook a study to uncover why Moroccan women experience less skin aging at menopause. Their studies tried to find a scientific explanation of how applying cosmetic Argan Oil to skin and eating Culinary Argan Oil as a supplement could improve skin elasticity in post menopausal skin.
The Cause of Aging in Post Menopausal Skin
Changes in the Skin
A 2014 study evaluated the effect of daily consumption and/or application of argan oil on skin hydration in postmenopausal women. The study discovered that using argan oil has led to a significant decrease in transepidermal water loss and a significant increase in water content of the epidermis. 
Your skin is made up of two layers the epidermis and the dermis. The dermis is made up of fibroblasts that produce the collagen and elastic fibres that allow stretching to take place and maintain elasticity.
However, during menopause there is a lowering in oestrogenic secretion. This hormone level drop reduces skin elasticity because it causes a decrease in dermal fibroblasts collagen and elastic fibres
The decline in endogenous oestrogen levels in post menopausal women reduces skin elasticity. It can lead to a loss of collagen in the skin of up to 30% during the first 5 years after menopause.
This is a decline of 2.1% per post menopausal year over 15 years. This decline in collagen further contributes to the acceleration of degenerative changes in dermal elastic fibres.
It is these changes that can lead to other post menopausal symptoms for women’s skin. These include break out skin, acne, blotching and other changes.
Metabolic Changes Affecting Collagen and Fibrer Synthesis
Decreases in collagen and elastic fibre synthesis are due to the loss of oestrogen, which represents the antioxidant hormone of the human body.
The lower oestrogen levels lead to an increase in “reactive oxygen species” – chemically reactive molecules that contain oxygen. These reactive oxygen species cause an imbalance in the synthesis of “transforming growth factor-beta” (TGFβ), a small protein involved in the activation of cell growth, collagen and elastic fibre production. This imbalance favours the activation of “metalloproteinases” (MMPs) which degrade collagen and elastic fibres.
It is clear then that oestrogen treatment could have a beneficial effect and reverse the signs of skin aging by maintaining skin elasticity in post menopausal women. However, there is some concern over side effects from the long term use of hormone replacement therapy.
Clearly, if a natural way to rebalance the production of collagen and skin fibres through diet and skin care changes could be proven then it would be desirable.
Scientists now know that the consumption of culinary Argan oil as a natural supplement is proven to have a positive effect in the treatment and prevention of:
- high cholesterol 
– heart disease 
– Diabetes 
They noticed that these same diseases also have high incidence in Post Menopausal women .
So, could the same changes, that lead to these diseases, that appear to benefit from Argan Oil supplement be connected with the loss of collagen and fibre production in the skin?
How did they test this theory?
A study was conducted with a group of 60 Post Menopausal women to observe the effect of daily culinary Argan Oil consumption in the diet and/or the application of a cosmetic Argan oil for skin care.
The results would be evaluated by using recognised standards of measurement for skin age known as “R” parameters. R-parameters identify the bio-mechanical property of your skin.
Research was only concerned with measuring improvements in skin elasticity ( age ) and not with other problems and changes to post menopausal skin such as dryness, itchiness, rashes or oily skin breakouts.
Three “R” measurements are used:
1: Gross- elasticity of the skin – R2
2. Net elasticity of the skin – R5
3. Biological elasticity – R7
4. Cutaneous Resonance running time [RRT] which is a way to assess skin elasticity.
The study was divided into two groups of 30 women and lasted for 60 days.
During the study none of the subjects were allowed hormone replacement therapy, or to use other anti-aging products or vitamin supplements for skin.
Culinary Argan Oil was consumed as a dietary supplement by a group of 30 women at 25 ml/day.
A different, but also highly beneficial oil for skin, Olive Oil, was chosen for the control group. The control group of 30 women were given 25 ml/day of Olive oil.
Both of these groups used cosmetic Argan Oil on their skin every night.
The Synergistic Effect of Using Both Eating Argan Oil and Cosmetic Argan Oil in Combination
It was noticed that in the group who were eating culinary Argan oil as a food supplement, as well as cosmetic Argan Oil externally as a skin treatment, there was the greatest improvement. The test group that was given Olive oil to eat and cosmetic Argan to apply saw no statistically significant improvement over the use of cosmetic Argan Oil alone.
It is supposed that these results are due to the higher antioxidant content of Argan oil -nearly double that of Olive oil. These antioxidants are mostly vitamin E as well as polyphenols, especially phenolic acid ( ferulic acid ). Vitamin E improves skin elasticity by the decreasing the quantity of TGFβ – transforming growth factor-beta”. The result is more messages to the cells fibroblasts to produce more collagen and elastic fibres. Treatment with Argan oil supplement increased the levels of vitamin E in the bloodstream of post menopausal women. Much more so than Olive oil.
Ferulic acid, present in Olive and Argan Oil component is a phenolic compound which has been used as a food additive to prevent oxidation as it stays in the blood longer than other antioxidants. It is thought that the synergistic antioxidant effect of vitamin E and ferulic acid combined is key to the maintenance of skin elasticity.
There are also two mystery nutrients, sterols, called schottenol and spinasterol present only in Argan Oil. The effect of these on skin elasticity is unknown.
The effects of high levels of anti oxidants, that can affect cell growth signals, can explain why there is a side-effect-free improvement in skin elasticity when taking eating Argan oil as a supplement.
Culinary Argan Oil – 2×6.76fl oz
Culinary Argan Oil has a Delicious Nutty Flavour. Use 10 to 15ml per day for nutritional supplement.
13.53fl oz Argan Oil for Eating
Test results were scientifically verified by the measurement of “R-parameters” (R2, R5, and R7).
The tests revealed that over the 60 day test period that:
1.The consumption of Argan oil led to a significant increase of gross-elasticity of the skin (R2), net elasticity of the skin (R5) and biological elasticity (R7). Furthermore there was a significant decrease of Resonance running time
2.The application of Argan oil led to a significant increase of gross-elasticity of the skin, net elasticity of the skin (R5) and biological elasticity (R7). There was also a significant decrease of Resonance running time.
The conclusions suggested that the daily consumption and/or topical application of Argan oil produces an improvement in skin elasticity.
This research into Argan Oil seems to have uncovered the fact that aging in post menopausal skin could be due to a process that could possibly be slowed or even prevented by taking higher levels of antioxidants and in particular Vitamin E in the diet or by supplements. It may also be the case that the other complex blend of nutrients in Argan Oil contribute to this effect.
How Much Argan Oil is Needed for a Post Menopause Skin Treatment
To say how much cosmetic Argan Oil is needed for a 60 day course is difficult to estimate. It, of course, depends on the total area being treated. Generally a 1 x 65ml bottle of cosmetic Argan oil for external use should be sufficient for at least one month to 6 weeks.
During the research a total of about 1.5 litres ( 25ml per day x 60 days ) of Culinary Argan Oil was eaten. This would require about 7 x 200ml bottles.
