    AzGl

    Azelaic acid + glycolic acid

    Studied together, still sting-prone

    AzSa

    Azelaic acid + salicylic acid

    Two acids, split timing

    Azelaic acid can sting and salicylic acid labels warn of irritation with another acne medicine, so using them at different times is gentler.

    AzAd

    Azelaic acid + adapalene

    Split morning and night

    Both can irritate at first, so one in the morning and one at night is gentler than stacking them.

    Morning
    Azelaic acid, let it dry SPF 30+
    Night

    AzBp

    Azelaic acid + benzoyl peroxide

    Works together, split timing

    They work well together, but the benzoyl peroxide label warns of irritation with another acne medicine, so split timing is a safe precaution.

    Morning
    Azelaic acid, let it dry SPF 30+

    AzNc

    Azelaic acid + niacinamide

    Fine to layer

    Nothing harmful is known between them, so they can share a routine; azelaic acid’s early sting is the main thing to watch.

    AzHa

    Azelaic acid + hyaluronic acid

    Safe to layer

    Hyaluronic acid is a moisturizer, not an exfoliant, and no bad reaction with azelaic acid is known, so they layer safely.

    Morning
