Yao Yu-Chen treats chloasma in women

By Tang Shu-Liang

Dr Yao Yu-Chen was an experienced gynaecologist in the city of Nantong with whom I studied for many years. I found that because his treatments for chloasma in women were particularly efficacious and rapid, the number of patients seeking his help for this problem grew into an endless queue. As his approach to diagnosis and treatment quite clearly had an internalised rationale behind it, I have set it out accordingly.
