Recently, the research and development team led by Professor Liu Wei from Baisi Kairui and Wuhan Zhongke Optics Valley (a wholly-owned subsidiary of Jiabiyou) have achieved important research and development results in the co delivery of bird's nest acid series nanocarriers and DHA series nanocarriers. Five highly active transdermal delivery products have been developed around this project, and five Chinese invention patents have been applied for. Due to the outstanding novelty and creativity of the research and development work, all five invention patents mentioned above have been successfully granted Chinese invention patents. These five research and development achievements adopt the "transdermal co delivery nanocarrier technology" of the National Nanodrug Engineering Technology Research Center, based on the concept of "precision skincare". By accurately anchoring the skin targets and functional pathways of different efficacy skincare products, precise screening and scientific combination of efficacy ingredients are carried out with bird's nest acid and DHA as the core efficacy ingredients, and suitable transdermal co delivery nanocarriers are constructed to achieve precise transdermal delivery of skincare core efficacy ingredients. Based on the above-mentioned patented technology, a series of skincare nano carrier products with bird's nest acid and DHA as the core functional ingredients have been developed.
