I am a huge fan of the scinic honey ampoule but wanted a product that has a pump. I didn't realize how strong the active ingredient was in this product and so find that I can only use this product every three days to avoid irritation as I have very dry skin that works best with very low amounts of vitamin c. This product would probably work best with someone who has oiler or combo skin, or a strong skin barrier,  as I found that is was breaking down my skin barrier when I was using it too often. That said it works well at doing what you would hope a product containing vitamin c would do.
