<![CDATA[Ultraviolet (UV) radiation exposure can cause oxidative stress and damage the skin, highlighting the need for protection using natural cosmetic products like sunscreens. This study aims to formulate green tea leaf extract (Camellia sinensis) into sunscreen creams using different concentrations and to evaluate their physical properties. The research used an experimental method by adding the extract to a cream base at 5% (F1), 10% (F2), and 15% (F3). Physical quality tests included organoleptic checks, homogeneity, pH, spreadability, adhesion, viscosity, and antioxidant activity using the DPPH method. The results showed that all formulas met the standards for topical use, featuring a semisolid form, soft texture, pH of 5 to 6, spreadability of 5.20 to 6.30 cm, adhesion of 2.09 to 2.12 seconds, and viscosity of 3,533 to 3,544 mPa·s. Higher extract concentrations changed the color and aroma and reduced spreadability. Additionally, the antioxidant test showed that the formula with 15% extract had an IC₅₀ value of 785.84 ppm.]]>
