I have been using this product since 2014, but i dont really understand its function onto my skin. Later, after bunch of products i have been using.. then i understand this hada labo really works well to hydrates, calm, and brightened my skin. I have stop for a while now using hada labo because i interested in using cosrx, ordinary and skin1004. But i realize that my skin tend to be so dry if im not using moisturizer.. then i go back to using hada labo and surprizingly, i dont get any irritation when i exfoliate my skin after using this hada labo. I really have found a really good match for my skin! ❤️❤️❤️
