I've repurchased this essence after finishing my previous bottle, this product doesn't cause any skin irritations on me. I like to put this in a spray bottle, directly spraying it on my face because it's easy to use and no product is wasted with cotton pads
 

Improves skin texture, I noticed the small wrinkles around my eyes diminish, and for my hormonal breakouts it keeps them more calm than any product I have ever used... As you can see.
