Science
Mechanism of Action
Manganese Citrate acts as a robust antioxidant by serving as a cofactor for the enzyme superoxide dismutase, effectively neutralizing reactive oxygen species and free radicals that contribute to premature skin aging and cellular damage. It plays a vital role in wound healing and skin regeneration through the activation of enzymes necessary for collagen synthesis, thereby enhancing skin barrier integrity and elasticity. The ingredient also exhibits anti-inflammatory effects, which help alleviate discomfort, redness, and swelling associated with inflammatory skin conditions like acne and eczema. Furthermore, Manganese Citrate supports cellular metabolism, repair, and renewal processes, fostering revitalized and healthy skin, and may contribute to reducing wrinkles by influencing neuromotor influx and muscle fiber contraction.

Key findings
- 01 Research indicates that manganese, including its citrate form, at concentrations spanning from 0.0001% to 10%, effectively diminishes the appearance of wrinkles and fine lines, contributing to a smoother skin surface.
- 02 A facial serum featuring a manganese peptide complex (Manganese Tripeptide-1), applied twice daily for up to 12 weeks, demonstrated improvements in various signs of cutaneous facial photodamage, particularly hyperpigmentation. This treatment was well tolerated, with no significant cutaneous inflammation observed.

Stability
Manganese(III)-citrate complexes exhibit stability in neutral aqueous solutions (pH 4.5–6.6) for several days when citrates are in excess relative to Mn(III) ions. The pH of a 5% w/v aqueous suspension for FCC Food Grade Manganese Citrate is typically between 4.5 and 6.0 maximum. While described as slightly soluble in water, its solubility is enhanced in the presence of sodium citrate.
Synergies
- Sodium Citrate (enhances solubility)
Conflicts
- Strong oxidizing agents
Safety
Safety Profile
The CIR Expert Panel assessed the safety of inorganic citrate salts, including Manganese Citrate, concluding they are safe for use in current cosmetic practices and concentrations. Additionally, Manganese Citrate is affirmed as Generally Recognized As Safe (GRAS) by the FDA for direct use as a human food ingredient (nutrient supplement, sequestrant) without specific concentration limits beyond good manufacturing practice in various food categories and infant formulas.
