Carrier Oils For Aromatherapy

Some research shows that external applications of black seed oil could benefit skin conditions like acne due to its antimicrobial and anti-inflammatory propertiesTrusted Source.

A 2020 study found that using a topical gel made with black seed extract twice daily for 60 days reduced acne severity by 78%Trusted Source. Researchers also noted a significant improvement in the number of acne lesions in study participants compared to those in a control group.

Research suggests that Nigella sativa extract has anti-inflammatory benefits, and animal studiesTrusted Source suggest that black seed oil could reduce skin inflammation and other symptoms of psoriasis.

A 2017 reviewTrusted Source also found that combining oral and topical forms of black seed extract reduces symptoms of psoriasis and improves skin lesions.

That said, it’s important to remember that more human studies are needed.

Black seed oil contains a compound called thymoquinone, which, when applied directly to the skin, may stimulate tissue growthTrusted Source and facilitate wound healing.

Animal studies have found that thymoquinone may help treat burns, excisions, and other types of wounds due to its anti-inflammatory, antioxidant, and antibacterial effects. The oil seems to increase collagen production and have moisturizing effects, both beneficial to wound healing.

May support hair health and growth

Black seed extract may be good for the hair. It’s often added to hair care products, including masks and shampoos.

A 2020 review highlighted a small study in which the daily use of a Nigella sativa extract lotion for 3 months significantly increased hair density and thickness in people with telogen effluvium, a common form of hair loss.

The same review found a study with 90 participants using different seed oils for hair loss. Nigella sativa oil was the most effective at reducing hair loss.
