I'm in love. The trial kit lasted me for like 2 months, with me using it every morning and not being particularly stingy about it. There's still some of the serum left, even. So imagine how much these big bottles are going to last.
I purchased the whole line because it's honestly really good. I have the weirdest skin type on earth (sensitive, acne-prone, with an oily t-zone and the rest of my face being normal to dry) and I have to moisturize it everytime after cleansing it because even my t-zone feels dry and tight and uncomfortable if I don't do it. This line has changed my skin tremendously. It's moisturizing but it doesn't feel oily, sticky, nor heavy on the skin. My t-zone doesn't get oily throughout the day and my skin feels nice even under me constantly moving into different temperatures.
And it also smells sooooooo good you'll fell in love with the products just opening the bottles. I definitely recommend the whole line.
