Generated: 2026-09-16T18:18Z - **INCI name:** Potassium Azeloyl Diglycinate - **Common name:** Potassium azeloyl diglycinate - **Evidence tier:** literature-backed - **Functions:** tone-support, soothing ## What it does Potassium azeloyl diglycinate is a derivative of azelaic acid in which the acid is bound to two glycine molecules and neutralised as a potassium salt. The change matters for formulation: azelaic acid is poorly soluble in water and gritty at useful levels, while this derivative dissolves cleanly into a light, clear serum at a skin-compatible pH. Supplier and cosmetic literature describe it as sebum-normalising and tone-evening, with a moisturising contribution from the glycine portion. In use it is chosen for formulas aimed at the look of post-blemish marks, patchy tone and shine on oily zones, particularly where a gentler feel than azelaic acid is wanted. It is non-acidic, does not increase sun sensitivity and sits comfortably alongside niacinamide, tranexamic acid and hydroxy acids in a multi-active formula. Most of the published evidence sits with the parent molecule, azelaic acid, so we label this ingredient literature-backed at the level of mechanism and supplier data rather than borrowing the parent molecule's claims. ## Notes Potassium azeloyl diglycinate is a derivative of azelaic acid in which the acid is bound to two glycine molecules and neutralised as a potassium salt.
