Role of medicinal and aromatic plants in modern cosmeceuticals

This review article explores the significant role of medicinal and aromatic plants (MAPs) in modern cosmeceuticals, a category of skincare products that merge the benefits of cosmetics and pharmaceuticals. The origins of cosmeceuticals trace back to traditional plant-based preparations for skin health and beauty enhancement, which have evolved into advanced formulations combining nature's efficacy with scientific innovation. While not officially categorized by regulatory bodies, cosmeceuticals are recognized for their ability to improve skin texture, pigmentation, hydration, and elasticity while addressing minor skin disorders. The versatility of MAPs in cosmeceuticals stems from their rich composition of bioactive compounds such as antioxidants, essential oils, flavonoids, and vitamins, which offer moisturizing, anti-aging, skin-brightening, anti-inflammatory, and anti-acne properties. Additionally, the application of MAPs extends to hair care and aromatherapy, utilizing specific plant extracts to nourish hair, soothe the scalp, and enhance sensory appeal. Key ingredients include chamomile, Centella asiatica, liquorice, neem, green tea, turmeric, rosemary, and essential oils from plants like lavender and eucalyptus. This review highlights the increasing consumer preference for plant-based cosmeceuticals, alongside discussions on sustainability, traditional ethnobotanical knowledge, and advancements in extraction methods for optimizing bioactive compound efficacy. The continued exploration of MAPs provides potential pathways for developing sustainable, multifunctional cosmeceuticals, with applications that address both aesthetic and therapeutic needs in modern skincare.
