Eucalyptus targeted Luohe freckle washing mainly reaches mesoderm through nano-scale transdermal technology, and multi-dimensional targeted treatment is carried out for the causes of chloasma. However, this method has some limitations in the depth and breadth of treatment, and it is difficult to cover all pathological parts.
