Bionic film: refers to the fact that after lipstick is applied, a protective film with a structure and function similar to that of a sebum film will be formed on the lips. Most of our skin on our face is protected by a layer of sebum film, but there is almost none on our lips. This is the reason lips are prone to dryness and peeling after removing lipstick. Perfect Diary's first bionic lip film - Biolip, specializes in pomegranate peptide complex and combines biotechnology to create a bionic sebum film for lips.
