Acne vulgaris is a widespread dermatological condition, especially among adolescents and young adults. Due to increasing resistance and side effects associated with synthetic treatments, herbal alternatives are gaining interest. This study focuses on the development and evaluation of a natural anti-acne serum using Moringa oleifera leaf extract, known for its anti-inflammatory and antimicrobial properties.

Methods: Fresh Moringa oleifera leaves were collected, shade-dried, and extracted using maceration with 70% ethanol over 72 hours. The extract was then incorporated into an herbal serum formulation using aloe vera gel as the base, lecithin as the emulsifier, honey as a preservative, rose water for soothing effects, and tea tree oil for its antibacterial properties. The final serum underwent physicochemical evaluation, including organoleptic examination, pH measurement, viscosity analysis, smear test, homogeneity test, and stability testing under varied conditions for 4 weeks.

Findings: The formulated serum exhibited a pleasant herbal aroma and a light brown color. The pH was recorded at 4.65, which falls within the ideal acidic range for facial application, enhancing skin barrier function and antibacterial activity. The viscosity was measured at 4. 21Pa.S, indicating a lightweight and easy-to-apply serum texture. Homogeneity and smear tests confirmed a uniform, smooth application with no visible separation or grittiness. Stability studies demonstrated no significant changes in color, odor, or texture, confirming the formulation’s physical stability over time.

Interpretation: The herbal serum developed in this study showed promising results in terms of stability, safety, and usability. The formulation is free from synthetic preservatives or additives, making it suitable for sensitive and acne-prone skin.
