Formulation consisting: HPMC, tween 80, glycerin, PEG 400, sodium EDTA, sodium benzoate and triethanolamine. Evaluation is conducted to the extract antibacterial activity, face serum bacterial activity and face serum stability. The extract exhibits 0.860 gram/mL MIC50 Cutibacterium acnes, meanwhile, the face serum provides 15.30 ± 4.03 mm inhibition zone. Ultimately, the face serum is stable after 4 weeks testing using accelerated stability test in terms of organoleptic, pH and viscosity.
