i can understand your concerns.According to your history i think its just the sunlight that is affecting your complexion.So try to avoid sunlight especially between 9am - 4pm,liberally use sun block or screen of SPF more than 30,have a good night sleep,and drink plenty of water(2-3l) a day with vegs and friuts in your diet.
And please do not use the creams and ointments
suggested by someone as it can do more harm than benefit. ALWAYS go to a dermatologist
so the bottom line is i think you dont need this cream at this point,try whatever i have suggested for a month and contact me back with results.
all the best
