What Does Burning Sensation On Face After Using Skin Lite Cream Indicate?

Hi , I'm using skin lite cream , initially i got a good result , If i stop using it for couple of days r 3-4 days my skin is going very dark & some times after I wash my face I feel like burning sensation on my face ! So I'm continuing to use skin lite since from 1 year 6 months ! Please suggest me a good solution & to retain my fairness ! Thanks in advance
