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 stratum corneum 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 that, through various mechanisms, eliminates free radicals from cells and prevents them from causing damage to DNA and proteins such as 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 tumor necrosis factor (TNF-α). These compounds play a role in the onset of redness and inflammation.
