What order do I apply azaleic acid and vitamin c in the morning?

I’m trying to determine which order to incorporate vitamin c and azaleic acid into my routine in the mornings. I’ve been researching and reading a ton of posts and watching videos, but I’ve seen so many mixed things. These are my current products:

Cleanser

Byoma Redness Relief Soothing Toner

Vanicream Vitamin C

Azaleic Acid 15% prescription gel

Khiel’s Avocado Eye Cream

Purito Oat-In Calming Gel Cream

I’ve seen toner before vitamin c, I’ve seen vitamin c first, I’ve seen serums before both vitamin c and azaleic acid, etc.

Just trying to get the benefits and avoid pilling or irritation!
