Brassica Campestris (Rapeseed) Seed Oil

Brassica campestris (rapeseed) oil is the non-fragrant oil extracted from the seeds of a plant that is a member of the cabbage family.

Brassica campestris seed oil works primarily through emollient action, meaning it fills gaps between skin cells and creates a protective layer that reduces water loss. The fatty acids in the oil are similar in structure to those naturally present in healthy skin.The vitamin E content also provides antioxidant protection, which may help protect skin from environmental stressors, though the concentration in skincare products is typically modest.

Brassica campestris seed oil is typically encountered as part of a broader formulation rather than as a standalone product, so follow the usage instructions of your specific skincare product. If using an oil-based product containing this ingredient, start with a small amount and adjust based on your skin's response. It can be used morning or evening, depending on the formulation and your skin type preference.

Generally well-tolerated and safe for topical use. Those with known sensitivity to rapeseed or related plants should patch test first. It may not be suitable for acne-prone skin in high concentrations due to its occlusive nature.
