Cosmetics Formulation Development

Hello, I made a cream to cure acne. The old formula uses Alpha Arbutin (Switzerland) but thinking of changing it to Azelaic Acid (Liquid Azelaic™) would like to know Azelaic Acid (Liquid Azelaic™) Alpha Arbutin (Switzerland) does a similar function, right? Can you switch to this one? Read the details and have the same brightening properties. But this one reduces oiliness on the skin. Control the oil production of pores, reduce สิวอุดตัน too, so I thought I'd change the formula, thank you.

Hello, the work is different. Alpha Arbutin acts as whitening alone Azelaic Acid reduce สิวอุดตัน , ลดความมันผิว , helps brighten your skin. can be used together By doing additional work because the working mechanism is different
