What is ATDS (the Amphiphillic Transdermal Delivery System)?

The ATDS system allows formula to penetrate the skin rapidly down to the dermis to achieve maximum result of tissue repair. The function of ATDS requires a solvent in a form of molecular level smaller than the nano to penetrate epidermis. The combined mechanism of a sustaining penetration system and the EO ”floating system” allows the aqueous and the hydrophobic propo

The Innovation of L-Ascorbic acid technology

Further to the breakthrough solutions in 1999 to the stability and high concentration, a Technology difficulty to the ester-C and nano-C, Dr. Chen introduced the Amphiphilic Transdermal Delivery System ATDS)in 2003 to the market with U.S.patent.
