The fusion of technology and skincare has birthed an innovative product that not only targets facial imperfections but does so with a cryptocurrency twist. A novel campaign titled “On-Chain Summer” brings together the established Ethereum layer-2 network, Base, and the pioneering on-chain beauty brand, KIKI World. They've unveiled a unique form of pimple patches, which are linked to non-fungible tokens (NFTs) featuring the caricatured image of Coinbase CEO, Brian Armstrong.

Striking the balance between utility and style, each BASE FACE NFT is your key to unlocking a physical set of 40 patches. These aren't ordinary patches — half bear the likeness of Armstrong in various sizes, while the rest are adorned with the Base network symbol. Ownership of these NFTs allows individuals to mint the patches for the equivalent of about $12 in Ethereum.

KIKI World's co-founder, Jana Bobosikova, has shared that their vision with these patches goes beyond their practical use of cleaning pores and combating acne. Instead, they view the patches as a statement piece, merging fashion with digital culture. The inspiration for including Armstrong's illustrated face arose during the collaborative discussion, focusing on a design that appeals to all genders.

Engaging with the community, those who connect their purchased NFTs to a KIKI World on-chain account will gain the opportunity to influence future beauty products and designs. KIKI World's recent advancement is marked by a major investment spree, attracting funds from cryptocurrency and beauty industry leaders, showcasing the potential intersection of beauty and blockchain technology.
