Introduction The global trend in the cosmetics and skincare industry is currently shifting towards products made from natural ingredients . ack to This is driven by increasing consumer awareness regarding the safety and potential long-term side effects of synthetic ingredients, as well as environmental sustainability. Body scrub, as a body care product that functions to cleanse, remove dead skin cells . , and hydrate the skin, is one of the products widely developed by utilizing natural resources. Skin is the largest organ of the human body and serves as the primary barrier against environmental aggressors such as ultraviolet (UV) radiation, pollutants, and microbial Daily exposure to these stressors accelerates skin aging and can lead to dryness, appropriate skin care is not practiced. Exfoliation is an important component of skincare routines because it facilitates the removal of corneocytes, improves skin texture, and enhances the penetration of topical agents. In recent years, there has been a marked shift from conventional synthetic cosmetics toward natural and herbal-based formulations. Consumers increasingly associate AunaturalAy or AuherbalAy cosmetics with better safety profiles, fewer adverse effects, and additional therapeutic Plant-derived ingredients rich in bioactive compounds, such as polyphenols, flavonoids, and triterpenoids, are widely used in skin-care products for their antioxidant, antiinflammatory, photoprotective properties. This trend is also supported by increasing scientific and patent literature focusing on natural ingredients for cosmetics and Auclean beautyAy concepts. Body scrubs are popular cosmetic products designed to mechanically exfoliate the stratum corneum by combining abrasive particles with an appropriate base and functional additives. A well-formulated scrub should effectively remove dead skin cells while maintaining barrier integrity and minimizing Traditionally, synthetic microbeads and aggressive surfactants were frequently employed as exfoliating and cleansing agents. however, concerns about microplastic pollution and skin irritation have driven interest in natural exfoliants and herbal scrubs. Recent studies on herbal facial and body scrubs demonstrate that plant-based formulations can provide gentle antimicrobial, and anti-aging benefits.
