Comparison of Alpha Arbutin and Azelaic Acid Functions and Combined Use in Acne Cream

Hello,

Based on your question and the staff's reply:

Alpha Arbutin (Product ID 68) primarily functions as a whitening agent only.

Azelaic Acid (Liquid Azelaic™, Product ID 224) has more diverse properties. In addition to helping brighten the skin, it also helps reduce clogged pores and control skin oiliness, which are properties suitable for the acne cream you are formulating.

Therefore, although both ingredients help with skin brightening, Azelaic Acid offers additional benefits for acne and oil control, which align with your needs for an acne cream formulation. Swapping from Alpha Arbutin to Azelaic Acid is a suitable option if you want to focus on acne treatment and oil control properties alongside skin brightening.

Both ingredients can also be used together in the same formula as they have different mechanisms of action and can complement each other.
