Development and Evaluation of a Herbal Lip Balm Containing Guava (Psidium Guajava) Leaf Extract

Lip skin is one of the most delicate and sensitive parts of the human body due to the absence of sweat glands and a very thin stratum corneum layer. Continuous exposure to environmental factors such as sunlight, wind, pollution, and dehydration leads to dryness, cracking, pigmentation, and premature aging of lips. Synthetic lip care products may cause irritation or allergic reactions upon prolonged use. Therefore, herbal cosmetic formulations have gained significant attention due to their safety, effectiveness, and minimal side effects. Guava leaves (Psidium guajava) are rich in bioactive compounds and antioxidants that exhibit antimicrobial, anti-inflammatory, and healing properties. The present study focuses on the preparation and evaluation of a herbal lip balm containing guava leaf extract. The formulation was prepared using natural ingredients such as beeswax, cocoa butter, shea butter, coconut oil, and vitamin E by the fusion method, while the extract was obtained using the maceration process. The prepared formulations were evaluated for parameters such as color, odor, pH, melting point, spreadability, stability, and irritation test. The results indicated that the formulations possessed good physical properties, stability, and no irritation, confirming their suitability for lip care application.
