help: 一句话不明白

speed_eriko

Cho Won-hyuk, college student, said, "I feel more confident after putting makeup on. When I put makeup on, it actually gets rid of my complex of having facial flushing. And I can focus more on what I do. At first, I think a few people started using makeup, and as we have such a small society, it soon became a trend."

红色高亮处的这句话是什么意思呢? 句中的complex 和 flushing怎么翻译比较好呢？
请指教，谢谢。

facial flushing = red face, use google image for examples.
complex = something the person is highly aware/concerned of.
facial flushing complex = being concerned about what others think of his red face problem.
