Design
We have designed two products, acne sticker and acne mask, they have the same structure but part of different feature. The acne patch is more lightweight and compact for daily use, while the mask has a wider range of functions. Their structures from the inside out are as follows: a layer of adhesive patch with pores on the top to stick the acne sticker and mask firmly on the face, the pores on the top can let the skin breathe freely while letting the Vb12 pass through easily, which is convenient for the engineering bacteria in the inner layer to absorb the Vb12; a layer of semi-transparent membrane, which can prevent the engineering bacteria from escaping, and at the same time the Vb12 can pass through and be absorbed by the engineering bacteria in the next layer; a layer of LB agar medium to cultivate the engineering bacteria; a layer of LB agar medium to cultivate the engineering bacteria. LB agar medium, which is the core of our product. Here Vb12 is absorbed by our engineering bacteria; then another layer of semi-transparent membrane, which can prevent engineering bacteria from escaping to the face and ensure the safety of our products; a layer of cover with pattern, our cover design is one kind of cute pattern, which is more beautiful for customers to put on it and easier to be accepted psychologically, and the other one is Chinese style seal engraving, which is beautiful and at the same time promotes the Chinese traditional culture.
