This is an amazing product. VitC is very good for your skin and helps speed up the cell turnover and nourishes the skin.
The packaging is great. A dark glass bottle that prevents the VitC to breackdown.
I use it after the AHA/BHA toner, because it works best with a low skin Ph.
I used it over a month and the result is magnificent! The skin is clear, clean and shiny (the good way).
I had no reaction to the acidic substance nor any irritation even though my skin is very sensitive.
Just remember to use an spf if you apply the product in the morning.
