Herbal cosmetics have gained widespread acceptance due to their safety, biocompatibility, and multifunctional benefits. Plant- and animal-derived ingredients contain diverse bioactive constituents that impart antimicrobial, antioxidant, cleansing, moisturizing, and anti-inflammatory effects. The present review compiles and analyzes the phytochemistry and cosmeceutical applications of selected crude drugs—Cymbopogon citratus (lemongrass), Berberis aristata (daruharidra), Sapindus mukorossi (reetha), and goat milk. Key constituents such as citral, berberine, saponins, lactic acid, and lipid fractions are discussed in relation to their mechanisms of action in skin and hair care. The review also highlights formulation considerations, current trends, challenges in standardization, and future prospects of these natural ingredients in modern cosmeceuticals. The integration of pharmacognosy and pharmaceutical chemistry provides a rational basis for their effective and safe use.
