I was not very knowledgable about skincare when I first tried this product, so I can't fault it for that, but I have to say it was extremely irritating for me.
If you're new to skincare and are looking for something for acne, I do not think you should start with this.
I'm honestly not sure what is in this that is supposed to treat acne besides Niacinamide, which I've come to suspect my skin may not like in any amount anyway - I think it irritates me and causes flakiness.
And on top of the potentially irritating niacinamide, it has ascorbic acid, which is crazy given that Numbuzin is not marketing this as a vitamin C serum whatsoever. Vitamin C is a good ingredient for some people, but it doesn't treat acne, and ascorbic acid is the most irritating form of it. Why is it in here??
AND it has three essential oils in it! For what? Again, essential oils are irritants and, as far as I know do not treat acne.
So, why would you put highly irritating ingredients that do not treat acne in a product that is marketed as an acne treatment? If anything, those will only worsen acne, as irritated skin tends to be more acne prone.
I don't know, maybe I'm missing something, given that this product is so highly rated otherwise, but I just wouldn't recommend it to anyone, personally.
