Originally, I didn't feel as if this product did anything or benefited me in any way. Was a bit disappointed as it wasn't the cheapest product out there. I stopped using it for a while but when my skin broke out a lot due to the overuse of active products so I decided to incorporate this ampoule back into my routine. I noticed an improvement in the redness and sensitivity of my skin. Would recommend if your skin is irritated and needs something to calm it down and take a step back from all the other products.
