The topical application of black seed oil.
The unsaturated fatty acids with which black seed oil is enriched give it nourishing and protective properties for the skin. Suitable for all skin types, it is particularly recommended for dry skin. Indeed, these do not produce enough lipids, which weakens their natural barrier. However, the linoleic acid contained in black seed oil reacts with the ceramides of the horny layer through an esterification reaction, during which the linoleic acid and lipids bind, forming the skin's waterproof barrier.
Furthermore, the application of black seed oil helps to combat skin sagging. Indeed, the thymoquinone in black seed oil is an antioxidant compound, which, through several mechanisms, eliminates free radicals from cells and prevents them from causing damage to DNA and proteins such as the collagen and elastin.
Finally, the anti-inflammatory properties of black seed oil make it a good supplement in cases of acne, eczema, psoriasis or rosacea. Studies have indeed shown that thymoquinone reduces the production of pro-inflammatory cytokines, such as interleukins 6 and 12 (IL-6 and IL-12) and tumour necrosis factor (TNF-α). These compounds play a role in the onset of redness and inflammation.
How to apply black seed oil?
Diluted in another vegetable oil.
It is important to know that black seed oil should never be applied undiluted to the skin. Depending on skin sensitivity, it is recommended to dilute it to 5 or 10% in another vegetable oil, such as argan oil or avocado oil for instance. You can then apply the oil to your body or face, taking care to avoid the eye area, as black seed oil can potentially irritate the mucous membranes. It can also be used as the final step in your routine, replacing your moisturising cream. Note that a few drops are sufficient and it is beneficial to accompany the application of the oil with a massage. This will ensure better absorption by the skin.
At Typology, we have incorporated black seed oil into our CBD botanical blend. This treatment is suitable for all skin types, but is particularly adapted for sensitive and fragile skin, prone to redness and in need of soothing. Combining the action of six botanical extracts, this night serum is used as the final step in your evening routine and can replace your moisturiser if you have combination to oily skin.
Diluted in a cream.
It is also possible to use black seed oil in synergy with a moisturising cream or a stretch mark cream. To do this, take a small amount of cream in the palm of your hand and add one or two drops of black seed oil. You can then apply the treatment by gently massaging it in and benefit from its nourishing properties.
Using black seed oil for hair care.
The application ofblack seed vegetable oil can be beneficial for dry and damaged hair. Thanks to its high content of oleic acid, an omega-9, it can provide nourishment. Moreover, it contains saturated fatty acids whose structure is similar to that of the lipids found in the hair cuticle, allowing them to integrate and strengthen this protective layer. Thus, black seed oil promotes the impermeability and cohesion of the cuticle, contributing to the overall protection of the hair fibre. By strengthening the cuticle, the hair becomes more resistant and reflects light better, giving it a shinier appearance.
How to use black seed oil for hair application?
To deeply nourish the hair, nigella vegetable oil can be used pure in an oil bath. This can be carried out once or twice a week to strengthen the hair and give it shine. To do this, apply a few drops of nigella vegetable oil strand by strand, starting from the mid-lengths and going to the tips, then let it sit for about fifteen minutes. It is important not to use an excessive amount of oil so as not to weigh down the hair. Nigella oil indeed has a rather thick and greasy texture. You can then proceed with a shampoo.
Black seed oil for protecting one's nails.
The numerous nourishing active ingredients contained within Nigella vegetable oil make its application beneficial for the nails. It is ideal for strengthening or repairing them if they are brittle or begin to split.
How to apply black seed oil on the nails?
Through massage.
To strengthen your nails, you can apply a drop of black seed oil to each one daily and massage until fully absorbed. After a few days, your nails will appear stronger.
As an oil bath or as a mask.
It is also possible to allow the black seed oil to work for a longer period by using it as an oil bath or a hydrating mask. For the bath, soak your nails in black seed oil for about twenty minutes. You can also wrap your nails, coated in black seed oil, in cellophane wraps for a night.
The oral intake of black seed oil.
Black seed oil also finds its place in the culinary field and has several benefits for the body and health. It can particularly strengthen the immune system, promote digestion, regulate metabolism, and support cardiovascular health.
How to use black seed oil for oral consumption?
To season dishes.
You can enjoy the various benefits of black seed oil by incorporating it into your meals, which will also enhance their flavour. It is primarily found in soups or salads, at a rate of one teaspoon to one tablespoon per day. It is generally not recommended to exceed this amount per day, as it may cause stomach discomfort. Moreover, be careful not to overheat the black seed oil, in order not to degrade the active ingredients it contains and to retain all its benefits.
As a dietary supplement.
Nigella oil capsules are also available, typically dosed at 500 mg to be taken four times a day for one to three months. This regimen helps to boost the immune system and facilitate digestion. Moreover, the antioxidant properties of nigella oil make it an excellent shield against oxidative stress which attacks the body's cells and causes them to age prematurely.
