About this ingredient
Rehmannia root extract (Rehmannia Chinensis Root Extract, traditional Chinese medicine name Shu Di Huang) is a Scrophulariaceae plant traditionally used in traditional Chinese medicine for 'yin deficiency' conditions. Active compounds are iridoids (catalpol, aucubin) and polysaccharides. Where applied. Rehmannia appears in niche Asian formulas for sensitive and mature skin (0.1-1%), often in multi-component 'traditional Asian medicine' blends. On the Spanish market it appears with niche K-beauty brands. Evidence base. In vitro: catalpol shows anti-inflammatory and antioxidant effects in cell cultures. No clinical topical RCTs in humans. Marketing claims of 'deep restoration' lack evidence support. Safety. EU CosIng permits use. Allergic reactions are rare, mostly in people sensitized to Scrophulariaceae plants. Pregnancy and lactation – use with caution. Orally, traditional Chinese medicine does not recommend it during pregnancy (theoretical estrogen-like effect and uterine stimulation). No topical data – safer to avoid in pregnancy and lactation formulas.
