I have got dark circle and sunken eye since 2008. Remedy not just on applying cream or gel. U need to work on both internal and external. Other than applying cream/gel, u need to do massage, change ur lifestyle, eating habit and take supplement. I don't know all these until my friend highlighted to me. He has got a testing kit to check on my 5 organs and he detected that I was overstress with work. As a result, sleepless night and low appetite. Fortunately, everything start to improve since last year November. At the same time, I also read a book written by a doctor "What your doctor doesn't know about nutritional meicine may be killing you". After reading this book, I begin to be more talkative...haha concern people and tell my surrounding people how to take care of ourselves. Note: Our beauty start from internal.
