Functions
Buffering
Chelating
Grabs onto metal ions in water that would destabilize the formula. Keeps your product from going bad or changing color.
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Astringent
Tightens and contracts skin tissue, temporarily shrinking pores and reducing oiliness. That "clean, tight" feeling after toner.
Antioxidant
Protects skin from free radical damage caused by UV, pollution, and stress
Moisturizing
Locks in moisture to keep skin soft and supple throughout the day
Fights Acne
Provides scent
Maintains optimal pH
Binds metal ions
Traditional Use
Citric acid from citrus fruits has been known since ancient times; sodium citrate was first synthesized in the 19th century. Used historically as a pH buffer and preservative in both food and cosmetics.
