Science
Mechanism of Action
This oil functions through its key bioactive constituents, primarily germacrone, which provides anti-inflammatory, antimicrobial, antioxidant, and cellular regeneration properties. The presence of azulene further enhances its potent anti-inflammatory, anti-allergic, and calming effects. These components work synergistically to inhibit comedone formation, reduce hyperpigmentation, improve skin hydration, and offer a natural protective factor against UV radiation.

Formulation
Stability
Geranium Macrorrhizum Herb Oil may crystallize when exposed to temperatures below room temperature. To return it to a liquid state, gentle warming in a water bath is required. Once seamlessly integrated into a base vegetable oil, it maintains its mobile liquid consistency and will not re-crystallize.
Safety
Safety Profile
Geranium oil, potentially encompassing Geranium Macrorrhizum, is Generally Recognized As Safe (GRAS) by the FDA for use as a flavoring agent. For topical application, it is generally deemed safe for most individuals when appropriately diluted with a carrier oil. However, undiluted application may lead to skin irritation, rash, or a burning sensation. The International Fragrance Association (IFRA) suggests usage levels up to 10% in fragrance concentrates, noting that alpha-bisabolol, a component, is restricted due to identified sensitization concerns. Specific safety assessments from the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) for 'GERANIUM MACRORRHIZUM HERB OIL' were not found.
