Which grade is higher, Qi Dan or Houhou?

Tian Qidan and Hou are both Korean skin care brands. Among them, Hou is the top brand in Korea, and Tianqidan is one of the high-end series. Therefore, from the perspective of brand grade, Hou is higher than Tian Qidan. In addition, the later Tianqidan series is the most advanced one in basic skin care, which has strong antioxidant effect and can fundamentally solve the problem of oil-water balance of skin.
