Science
Mechanism of Action
Rhodopseudomonas exhibits extraordinary metabolic versatility, allowing it to thrive in diverse environments and utilize various energy sources. Its extracts are believed to provide antiviral and antibiotic activity, contributing to therapeutic effects on skin disorders. The bacteria produce valuable compounds such as carotenoids (potent antioxidants) and other beneficial metabolites, which help counteract oxidative stress, support immune function, and promote skin whitening, moisturization, and softening. The presence of light-harvesting complexes also suggests a potential for modulating photosynthetic processes relevant to skin health.

Key findings
- 01 A topical cream containing 10% (v/v) extract from a related photosynthetic bacterium (Rhodobacter sphaeroides) significantly reduced skin moisture content loss and pruritus by 27.82% in clinical trials for atopic dermatitis. It also showed statistically significant improvements in skin pH (to 4.83), temperature, firmness, general appearance, and wrinkle states.
- 02 A liquid formulation with a cell concentration of 1 X 10^7 cells/ml, applied between 0.05ml and 0.7ml per cm², demonstrated benefits in skin whitening, moisturization, softening, and therapeutic effects for atopy and acne. When 1 to 30ml of this cell culture was mixed with 100ml of water-soluble cosmetics, similar cosmetic effects and potential prevention/treatment of viral skin infections were observed.

Stability
While a specific optimal pH range for Rhodopseudomonas ingredient stability in cosmetics is not fully defined, a related species showed an optimal pH of 7 for hydrogen production in a microbial context. Notably, a clinical study utilizing an extract from a related bacterium in a topical cream resulted in a skin pH of 4.83, suggesting compatibility or efficacy within an acidic product environment. Cell cultures are suggested for mixing with water-soluble cosmetic bases.
Safety
Safety Profile
No specific safety assessments by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS) were found for Rhodopseudomonas. The FDA mandates cosmetic product safety but does not pre-approve ingredients, excluding color additives.

Verdict
Rhodopseudomonas demonstrates promising multi-functional efficacy across various skin concerns, including significant improvements in moisturization, anti-aging, and therapeutic effects for conditions like atopy and acne. However, a comprehensive safety review by independent regulatory bodies is currently insufficient for a definitive safety and overall ingredient rating.
