Thymoquinone helps neutralize harmful free radicals and reduce inflammation, which is beneficial for maintaining healthy skin.
Furthermore, black seed oil is rich in essential fatty acids, such as linoleic and oleic acids, which are crucial for maintaining skin hydration and barrier function. These fatty acids help soothe and moisturize the skin, making the oil a valuable addition to skincare routines. The combination of these active ingredients makes black seed oil a versatile and effective natural remedy for various skin concerns.
