Azelaic acid for dark circles

[kcha.me]

is 20% azelaic acid too much for undereye purposes? should i switch into a lower concentration. im also using tret.25 since it's my first time using topical products

It could be depending on how thin and dry your skin is, but you could use it every day or less frequently until you can tolerate it more, but I wouldn't recommend azelaic acid for dark circles; only if it's slightly red, I'd recommend hydroquinone
