Soybean Oil

Generally safe·Strong evidence·INCI: Glycine Soja (Soybean) Oil

A nutrient-rich carrier oil from soybean seeds containing linoleic and linolenic acids essential for barrier function. Phytoestrogen content is present but not absorbed systemically from topical application, graded low concern by regulatory assessments.

The myth vs the evidence

Phytoestrogens in soybean oil are fearmongered as hormone disruptors, but the concentrations in topical products are negligible and research does not support absorption or systemic activity from cosmetic use.
