Environmental and Safety Considerations

Oenothera biennis sprout extract is generally considered safe for use in cosmetics and pharmaceuticals when used according to recommended guidelines. It is a natural ingredient with a low risk of irritation or allergic reactions. Environmentally, the sustainable harvesting of plant sprouts and the use of laboratory extraction methods contribute to a lower ecological impact compared to wild harvesting, supporting more sustainable production practices.

INCI


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
