Did nothing for my fungal acne. Actually did nothing at all.
(Compared to my cheap no-name Russian brand Azelaic acid cream which worked wonders).
What’s this mysterious Russian product ??? I’m all ears

One of my favorite products. If you're looking for an Azelaic Acid treatment, this is the right choice. It has the highest concentration you would find on an over-the-counter product (15%), combined with Ceramides and other soothing ingredients that will calm your skin and redness. Aside from rosacea, you can also use it for acne because it will soothe your breakouts and help fading the post-inflammatory hyperpigmentation. Is a very lightweight formula that gets absorbed super easy and rarely pills, so you won't find it hard to combine it with other products on your routine.
Sadly this is an old version of the product, but it performs as good as the new one, so don't worry because if you still get the old one you won't notice any difference. Although I have to admit that I liked this one better because It didn't had any scent at all, while the new one smells a little bit like old cheese (maybe some fermented ingredient) but I don't mind it at all, because it's still great.
