People with acne-prone skin, such as myself, have to be careful that anti-aging products don't cause breakouts due to their active ingredients, but I had not problems of the sort with this serum. It applies very smoothly and evenly and one pump is enough for my entire face, neck and decolletage. One 32mL container has lasted me 2 months and I apply morning and night. I notice that my skin is smoother and more radiant. It also smells delicate, but quite nice.
