Gu Yan Fang Xue's freckle removing principle focuses more on internal adjustment and external repair. The formation of human facial pigment spots is due to insufficient blood circulation regulation, local congestion and insufficient local nutrition supply, which leads to pigment spots.

The so-called temporary solution is not a permanent cure, but some melanin in the skin is wiped off with external cosmetics. Before long, the blood circulation and metabolism are not good, and pigment spots will appear on the face. Even if we don't cure the problem and unclog the circulation, the spots will still recur.

Yan Zhixue starts from the inside, plus external use, which is the best guarantee for completely removing freckles without rebounding.
