This study employed laser-induced breakdown spectroscopy (LIBS) to analyze elemental composition in face blusher powders.\u00a0 A Q-switched Nd: YAG\u00a0laser (1064 nm, 6 ns pulse duration, 10 Hz repetition rate) was used to generate plasma. Results showed that 13 elements were detected, including Aluminum (Al), Barium (Ba), Calcium (Ca), Chromium (Cr), Copper (Cu), Lead (Pb), Potassium (K), Lithium (Li), Magnesium (Mg), Sodium (Na), Titanium (Ti), Zinc (Zn), and Hydrogen (H). The plasma was strongest at the beginning and weakened over time. The plasma parameters, such as electron temperature and electron number density, were determined utilizing the intensity ratio method and the Stark line broadening profile method. The electron temperature was initially recorded at 8,555 K, while the electron number density was measured at 4.69\u00d710<sup>17<\/sup>\u00a0cm<sup>-3<\/sup>. Additionally, the plasma frequency was recorded at 6.16\u00d710<sup>12<\/sup>\u00a0Hz.<\/p><\/div><div class=\"item abstract\"><h3 class=\"label\">How to Cite this paper?<\/h3><div class=\"csl-entry\"><p><strong>APA- Style<\/strong><\/p><p>A.
