The black seed oil has been considered a miracle oil in the Middle East for centuries. It is currently gaining ground in the mainstream beauty industry as the ingredient for acne-free skin.
While other active ingredients like benzoyl peroxide and retinol are known as popular remedies for acne, these sometimes have side effects like dryness, stinging, itchiness, and burns.
Black seed oil is presented as a natural option that is less invasive yet provides the same result. But is this oil really good for acne-prone skin? In this guide, you will find everything you need to know about this wonder ingredient.
What is black seed oil?
Black seed oil is obtained from the cold press of the seeds of the Nigella sativa (fennel flower) plant. This plant grows in parts of the Middle East, Asia, Eastern Europe, and North Africa.
It has been used for over 2000 years in Asian, Aruyvedic, and Arabic cultures for its medicinal properties.
The pure and natural black seed oil has a golden brown colour. It has a shelf life of 2 years and is non-comedogenic. Its scent can be described as mild, earthy, spicy, or woody. It is also referred to as black cumin seed oil, black caraway oil, black onion seed, or kalonji oil.
This lightweight oil has antioxidant, anti-inflammatory, antibacterial, and antifungal properties that make it suitable for combination and acne-prone skin. These are also the reasons why a lot of brands today are turning to this natural oil to formulate products for acne treatment. Below are some of the incredible benefits of black seed oil.
Benefits of black seed oil for acne-prone skin
Destroys acne-causing bacteria
The black seed oil contains the active compound thymoquinone, a strong antibacterial that helps get acne vulgaris. This bacteria is responsible for the appearance of white and blackheads.
It has an essential fatty acid profile made up of linoleic acid (50.2%), oleic acid (19.9%), and stearic acid (2.5%). Its linoleic acid content helps unclog pores and regulate sebum production in oily skin, while oleic acid provides hydration.
A 2010 clinical study on 62 patients suffering from mild to moderate acne revealed that a 20% black seed oil lotion was more effective in reducing the appearance of acne lesions compared to a 5% benzoyl peroxide lotion.
Has strong antioxidant and anti-inflammatory effect
The black seed oil is packed with phenolic compounds (thymoquinone, thymol, carvacrol) and saponins (alpha-hederin) that give it antioxidant properties.
When exposed to free radicals, skin cells are damaged, causing inflammation in acne-prone skin. The antioxidants present in black seed oil help prevent that by reducing the oxidative stress and neutralizing free radicals present on the skin.
This oil equally works to smooth out signs of ageing. Its has high concentrations of linoleic acid helps to boost ceramide production for a healthy lipid barrier.
Facilitates the absorption of other skincare products
The black seed oil has a high concentration of linoleic acid. That makes it capable of enhancing the absorption of other products into the skin. It goes a long way to render the other products in your skincare routine more effective as they will be able to reach deeper layers of the dermis.
A recent 2019 study revealed that black cumin seed essential oil treats pathogenic yeast and dermatophytes fungi (a group of fungi that cause skin disorders.). This includes skin conditions such as fungal acne, facial, hair, and body ringworm; athlete’s foot, jock itch, and onychomycosis.
Heals acne scars
This oil has been known over the years to speed up wound healing like acne scars. While it doesn’t boost the production of collagen, it is effective in scar reduction. By reducing inflammation caused by acne, it speeds up the skin healing process. Added to that, it helps inhibit the growth of bacteria that could lead to further pore infection.
Other benefits of black seed oil
Soothes eczema and psoriasis
When applied topically, black seed oil helps reduce inflammations and calms down itchiness caused by eczema flare-ups thanks to its anti-inflammatory properties. Tested on hand eczema it was proven to be more effective than Eucerin.
The black seed oil also helps treat psoriasis. It is proven to boost the immune system and inhibit the reproduction of infected skin cells. Its antioxidant, anti-inflammatory, antibacterial and anti hostile effects all work together to prevent and treat psoriatic lesions on the skin.
Patients in this study who were treated with both the oil and oral doses recorded a complete cure.
Treats hypopigmentation and vitiligo
Hypopigmentation occurs when your skin cells fail to produce enough melanin. Vitiligo is a skin condition caused by the loss of the skin’s pigment-producing cells, also called melanocytes. In both cases, the result is the appearance of lighter patches of skin all over the body.
According to a review posted in the Journal of Dermatology & Dermatologic Surgery, thymoquinone, the most active ingredient present in black seed oil, induces melanin production when exposed to melanocytes.
When tested on patients in this clinical study, the topical application of black seed oil resulted in a decrease of the vitiligo area after six months of daily application.
