Abstract :

Lip hyperpigmentation is a common cosmetic concern associated with ultraviolet exposure, dehydration, smoking, and prolonged use of synthetic cosmetic products. Synthetic lip-lightening formulations may cause irritation and long-term adverse effects, necessitating safer herbal alternatives.
The present study aimed to formulate and evaluate a herbal lip-lightening scrub containing liquorice extract for the management of lip hyperpigmentation. Three formulations (F1, F2, and F3) were prepared using liquorice powder, beetroot powder, strawberry powder, beeswax, petroleum jelly, sesame oil, coconut oil, honey, vitamin E, and strawberry essence. The prepared formulations were evaluated for organoleptic properties, homogeneity, pH, spreadability, abrasiveness, washability, solubility, irritation test, moisturizing effect, microbial limit test, and stability for one month at room temperature.
All formulations showed uniform appearance, pleasant odor, and good homogeneity without phase separation. The pH values were found to be 6.7 ± 0.2 (F1), 6.4 ± 0.1 (F2), and 6.1 ± 0.1 (F3), indicating compatibility with lip skin. Spreadability diameter was recorded as 5.8 cm (F1), 6.5 cm (F2), and 5.2 cm (F3), demonstrating satisfactory ease of application. Abrasiveness testing revealed gentle and non-irritant exfoliation in F1 and F3, while F2 showed mild exfoliation. All formulations were easily washable, with F2 and F3 leaving no residue.The irritation test showed no redness, itching, or discomfort in any formulation. Stability studies conducted for one month demonstrated no change in color, odor, or phase separation. Microbial limit testing showed absence of visible microbial growth in all formulations. Among the formulations, F3 exhibited better moisturizing effect with soft and hydrated lips after application.
The developed herbal lip-lightening scrub demonstrated satisfactory physicochemical properties, stability, safety, and effective moisturizing performance. The formulation, particularly F3, may serve as a safe and natural alternative to synthetic lip-lightening products for improving lip texture and pigmentation.
