I've been using 10% Azelaic acid from The Ordinary for a few years but when I ran out a few months back didn't bother replacing it.
Unfortunately my skin is looking awful - bumpy, spotty dull -and I clearly need to reintroduce it back into my daily regime but The Ordinary one is sold out everywhere so looking for a new brand. I like the look of the Paula's Choice booster but can't afford £38 for just 30ml. Any suggestions?
