We used the optical coherence tomography instrument to obtain  the surface of the consumer＇s skin.  Accordingly, we build the skin model by 3D printing. We get the personal template, and apply our lab＇s polysaccharide material physicochemical database to pick up the material with which consumers don＇t have skin allergies and rubefaction. The material is filled in personal template, with active substance in the holes, then demolding. Microneedle array is obtained.

While subcutaneous injection can be used to deliver substances directly into the blood, this method requires trained personnel to operate.
Microneedle is a new generation of transdermal delivery system, it can effectively transfer substances to the skin or blood at a certain rate, reduce the absorption variability of substances and maintain the concentration of substances in the blood.

This invention can cooperate with the mask manufacturer to develop a microneedle mask which can increase the contacted area between  mask and skin. Then, we can work with the medical beauty clinic, the doctor evaluates the skin condition of the user and  scan the surface of the skin. Before returning to the clinic, we prepare a personal microneedle, loaded with the prescribed drug.
