  1. 1. Development and Evaluation of an Enzyme-Based Sunscreen

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Författare :Karolina Eriksson Torfgård; [2023]
    Nyckelord :Enzyme activity; UV-filter; Protease; Biotechnology; Technology and Engineering;

    Sammanfattning : Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. LÄS MER
