What makes azelaic special?
The best thing about azelaic acid is it's gentleness. It's generally well-tolerated and safe to use alongside other actives like niacinamide or salicylic acid.
Unlike AHAs, azelaic acid will not make you photosensitive/sun sensitive.
You can find this ingredient naturally occurring in grains like wheat, rye, and barley. In cosmetics, azelaic acid is typically lab-made, which is more stable and effective.

As a surfactant, it helps collect dirt and oils for washing. Emulsifiers prevent oils and water from separating.
Polysorbate 20 also adds scent to a product. Since it is made using sorbitol, it has a sweet scent. Sorbitol can also be found in fruits such as apples and peaches.
The lauric acid used to create Polysorbate 20 is often derived from coconuts.
Polysorbate 20 may not be fungal acne safe.

Another role of this ingredient is preventing a product from melting or freezing. Propylene glycol also adds antimicrobrial properties to a product, elongating product lifespan.
This ingredient is considered an organic alcohol and commonly added into both cosmetics and foods.
Those with sensitive skin or conditions may develop a rash when using this ingredient.
