<![CDATA[This study aims to formulate a lip scrub using coffee grounds and dragon fruit peel extract as a natural source of antioxidants. The extract was obtained through maceration with 96% ethanol, while coffee grounds served as an exfoliating agent. Variations of extract volume (0.3–2.7 mL) and coffee grounds mass (9.9–12.3 g) were tested for pH, homogeneity, melting point, organoleptic properties (texture, aroma, color), and antioxidant activity using the DPPH method. The results showed that all formulations had a pH of 4.5–4.9, in accordance with SNI 16-4399-1996, were homogeneous, and had a melting point of 62–65 °C. Organoleptic tests indicated that the natural coffee aroma and brown color were preferred by panelists, while texture was influenced by the ratio of coffee grounds to dragon fruit peel extract. Antioxidant activity increased with higher extract volume, with the highest value of 0.8259 mg vitamin C equivalent per gram of sample obtained at 2.7 mL extract combined with 12.3 g coffee grounds. This study demonstrates that the combination of coffee grounds and dragon fruit peel extract can produce a natural lip scrub that is effective as an exfoliant while providing antioxidant protection, making it a potential eco-friendly cosmetic product.
