As someone with super sensitive skin, I used to only use Avène mist. My skin would immediately get itchy and develop tiny red bumps if something didn't agree with it. However, this product has been fine for me. I'm almost through a whole bottle and haven't had any issues, which is great. I bought it after testing the spray at Olive Young and liking how it dispersed. I'm happy to have found a product that works hard for my skin!
As I saw in other reviews, there's the scent issue... I absolutely avoid cosmetics with added fragrances, and generally dislike products with any scent. While this product doesn't contain artificial fragrances, it does have a smell. In my purely subjective opinion, it's not a particularly pleasant one.
