Decent, think it helps with acne a bit.
I think it has helped with my hormonal/stress acne on my chin (which I've had for years, I'm in my 30s). I've been using it for about 3 months and I'm breaking out less, and the old red marks are improving. I also have been using Dema-E  Hyaluronic ultra hydrating serum and occasionally the Derma-E blemish control treatment as well as prescription retinol on occasion and overall my skin has calmed down. It's cyclical so we'll see if the improvement holds, but overall I'd say it's worth a try, considering Azelaic acid has been recommended by some dermatologists for this sort of thing.
