good
I dont know what difference its suppose to make because i havent tried it long enough but my skin is kind of sensitive and it did not irritate it attt allll lovvve that but just fyi if you use toner and this after it it might irritate a little but what i did is i used centella ampoule and then this and then moisturiser and it did not sting like it did with the toner hope that helps <3
