Before a 6 month I am personally used this cream. When I am starting to uae a cream that time this cream gives a response. In 1 or 2 week take to for your skins lite.in starting you will happy with this cream. If you regularly use this cream then automatically do you know whats was happening. When you cross the same week or month than your lite color skin cames into a red colour tones. And its look like a ur skine is harmful and red dotted. And again when you stopped the cream use than ur skin colour is comes into a balck.
