Excessive sun exposure caused skin redness, inflammation, and even skin cancer. One effective way to protect the skin from the sun is by using sunscreen. Nasi-nasi leaves (Syzygium zeylanicum (L.) DC) had the potential to serve as a natural sunscreen due to their phenolic compounds, which could absorb harmful ultraviolet (UV) rays. This study aimed to explore the potential of sunscreen gel extr…
