        abstract = {Lipsticks are one of the most widely used cosmetic products designed to enhance lip appearance while offering protection and hydration. Conventional lipsticks often contain synthetic dyes, heavy metals, and petroleum-based chemicals that may pose health concerns, especially due to unintentional ingestion during regular use. To overcome these limitations, natural and herbal lipsticks have gained significant attention due to their safety, biocompatibility, and availability of plant-based colourants. This review provides a comprehensive overview of lipstick history, anatomy of lips, types of lipsticks, ideal characteristics, advantages, disadvantages, and side effects. It also highlights various natural pigments such as beetroot, carrot, tomato, hibiscus, rose, turmeric, annatto, and purple sweet potato, along with their extraction methods. The general formulation steps, manufacturing procedures, and evaluation parameters including melting point, breaking point, pH, solubility, texture, and stability are discussed. Overall, natural lipsticks formulated with herbal colourants offer a safer alternative to synthetic products while maintain desirable aesthetic and functional properties.},
