Raphanus Sativus Root Extract

Raphanus Sativus (radish) root extract is typically used at low concentrations as an antioxidant/skin-conditioning botanical, and most users tolerate it well. However, botanical extracts contain multiple bioactive constituents and can trigger irritation or allergic contact reactions in a small but meaningful subset of sensitive/eczema-prone patients, especially in compromised skin barriers. Given that risk profile and the lack of strong evidence that it is universally inert, I rate it as gentle but not risk-free. Safety Notes: In commercial skincare, Raphanus Sativus (radish) root extract is most often used as a minor botanical/skin-conditioning component or part of a preservative blend, where it commonly appears around 0.01–0.5% (leave-on and rinse-off). Higher levels are seen in “natural/clean” formulas and some extract-forward serums/masks where the brand loads botanical extracts, with observed consumer-available products reaching ~1–5% depending on extract type and solvent system. The upper end is constrained mainly by sensorial impact, color/odor, and overall formula stability/compatibility rather than a specific global regulatory maximum for the extract itself.
