What Is Brassica Oleracea Gemmifera Extract?

Brassica Oleracea Gemmifera Extract is derived from Brussels sprouts, a cruciferous vegetable rich in phytonutrients, polyphenols, and sulphur-containing compounds. In skincare, it functions primarily as an astringent — a category of ingredients that may help to temporarily tighten the appearance of skin and refine pores.

The extract is used in formulae at relatively low concentrations, where its plant constituents are believed to offer mild binding and possibly antioxidant benefits to the skin barrier.

How It Works

Astringent ingredients work by temporarily contracting skin tissue, which can create a perception of tighter, smoother skin. This effect is usually short-lived and tends to be more pronounced on oily or combination skin types.

The bioactive compounds within the extract, including glucosinolates and polyphenols, may also contribute antioxidant activity, though the extent to which these remain stable and bioavailable in formulated products remains an open question.

Clinical Evidence & References

Research specifically examining Brassica Oleracea Gemmifera Extract in skincare is limited. The ingredient is primarily included based on traditional use and knowledge of the antioxidant and astringent properties of Brussels sprouts in general.

Whilst cruciferous vegetables are well-documented as nutritious foods, translating that benefit into topical skincare requires evidence of stability, penetration, and efficacy in finished formulations — data which remain sparse for this particular extract.

How to Use

This ingredient is typically formulated into toners, essences, and light serums rather than occlusives. If using a product containing Brassica Oleracea Gemmifera Extract, apply to clean skin as directed and follow with appropriate hydration and sun protection. Because astringents can feel drying, those with sensitive or compromised barrier function should introduce the product gradually and monitor skin response.

Safety & Precautions

Generally well-tolerated in cosmetic products. Those with sensitivity to brassica family plants or known fragrance sensitivities should patch-test, as plant extracts can occasionally trigger contact irritation in sensitive individuals.
