What is Potassium Azeloyl Diglycinate? Potassium Azeloyl Diglycinate is the combination of azelaic acid and glycine. Azelaic acid is a skin brightener and serum normalizer while glycine is a hydrating ingredient.
Let’s talk about azelaic acid first.
Azelaic acid has been shown to be a multitasking ingredient. It reduces hyperpigmented area or dark spots on the skin by inhibiting tyrosinase, the enzyme responsible for the production of melanin.
Azelaic acid also improves excessive sebum production which is beneficial in acneic skin.
Azelaic acid has also been documented to reduce inflammation and redness in rosacea patients.
Potential side effects of azelaic acid depends on the concentration. Common side effects include burning or stinging sensation. Redness and skin dryness can also happen.
By combining glycine, the hydrating agent, into azelaic acid has significantly increased the moisturizing effect; therefore, eliminates the potential stinging and redness with azelaic acid alone. That makes the combined ingredient, Potassium Azeloyl Diglycinate, more versatile in brightening treatment and other problematic skin condition.
