Moringa oil, an ally against stretch marks?

Stretch marks, also known as striae distensae, are scars that form when the skin undergoes a rapid distension. This causes the collagen and elastin fibres located in the deeper layers of the skin to rupture. There are many causes for the appearance of stretch marks: pregnancy, rapid weight gain or loss, hormonal changes, genetic predisposition, diet ... Initially, stretch marks are red or purple in colour as they signal inflammation of the dermis due to skin stretching. They then turn white. It is almost impossible to act on white stretch marks that have been present for a long time.

Rich in active molecules, moringa oil is sometimes cited as a natural solution for stretch marks. In reality, there currently exists no clinical study supporting this theory. We can only suppose that the moisturising, nourishing, antioxidant and healing properties detailed below of the moringa oil could potentially be beneficial in combating stretch marks.

• Moringa oil hydrates and softens the skin.

  The high content (≈ 70%) of oleic acid in moringa oil allows it to strengthen the hydrolipidic film present on the skin's surface. Half aqueous, half oily, this protective veil primarily serves as a barrier to limit water loss. By keeping the skin hydrated, it is likely that moringa oil ensures its suppleness, which may reduce the risk of stretch marks. Furthermore, moringa oil contains linoleic acid, a fatty acid involved in the synthesis of certain types of ceramides. Ceramides are lipids of the epidermis acting as intercellular cement and ensuring the cohesion of the horny layer. When this is consolidated, the skin is more resistant to weight variations and strains.

• Moringa oil protects the dermal fibres from oxidative stress.

  Free radicals generated by UV rays, pollution, or tobacco are known to degrade collagen and elastin, thereby weakening the structure of the dermis. They therefore indirectly promote the occurrence of stretch marks. However, it is possible to protect skin tissues from the effects of free radicals by incorporating antioxidants into your skincare routine. Moringa oil, containing carotenoids, vitamin E and phytosterols, can fulfil this role. These compounds indeed have anti-radical properties. Furthermore, studies in vitro have shown that moringa oil has an activating effect on catalase and superoxide dismutase, which are antioxidant enzymes.

• Moringa oil promotes healing.

  The high oleic acid content of moringa oil also gives it healing properties. Studies in vitro have shown that this fatty acid can stimulate collagen synthesis in a healing situation. Indeed, collagen is a key constituent of granulation tissue synthesised by fibroblasts. As a reminder, granulation tissue is a transitional tissue formed during the repair of inflammation. Furthermore, moringa oil appears to be able to intensify angiogenesis, that is, the development of new blood vessels. It can be assumed that these healing effects of moringa oil could allow it to act on purple stretch marks.
