Brassica Oleracea Italica (Broccoli) Extract

Brassica oleracea italica (broccoli) extract offers antioxidant benefits for skin and can help offset negative effects caused by environmental stressors (including sun damage). This natural plant extract can be derived from the leaves, flowers, or stems of broccoli.

Beta-carotene is one of the predominant beneficial antioxidants present in Brassica oleracea italica (broccoli) extracts, joined by others including vitamins A, C, E, quercetin, glutathione, and sulphorapane. In particular, sulphorapane is highlighted for its soothing effects.

Researchers have also studied Brassica oleracea italica (broccoli) extract for its pro-collagen effects. Brassica oleracea italica (broccoli) extract is considered an upcycled skin care ingredient when it is salvaged as a byproduct of agricultural processing. This is a welcome sustainable practice to reduce food waste.

Due to its antioxidant-rich nature, products with Brassica oleracea italica (broccoli) extract should be packaged in a way that limits air and light exposure (these elements degrade antioxidants). Think opaque, air-tight pump bottles or squeeze tubes as opposed to clear, screw-top jars.

Usage levels of Brassica oleracea italica extract in skin care range from 1–3%, with levels up to 5% being advised when this broccoli-derived ingredient is part of a blend.

Astringent ingredients work by causing mild contraction of the outer layers of skin, which can temporarily reduce the appearance of pores and mattify oily areas. This effect is largely mechanical and transient, lasting only whilst the product is on the skin.

The bioactive compounds in broccoli extract—particularly sulphur-containing compounds and flavonoids—may also contribute antioxidant benefits. Preliminary research suggests these compounds possess antimicrobial properties, though their effectiveness in finished skincare products requires further investigation.

Use as directed on product packaging. Astringent products are typically applied to clean skin, either as a toner or as part of a serum or lightweight treatment. Because astringents can be drying, always follow with appropriate hydration and moisturiser, especially if you have dry or sensitive skin. Begin with lower frequency if new to astringent ingredients, increasing as tolerated.
