The increasing demand for plant-based skincare products has promoted the development of herbal peel-off face mask gels with multifunctional cosmetic benefits. This review focuses on the anti-ageing and skin-rejuvenating potential of commonly used herbal ingredients and functional excipients in peel-off formulations. Polyvinyl alcohol (PVA) provides excellent film-forming properties for efficient removal of dead skin cells and impurities, while hydroxypropyl methylcellulose (HPMC) enhances gel consistency, spreadability, and stability. Glycerin acts as a humectant, maintaining skin hydration and improving elasticity, whereas phenoxyethanol ensures product safety by preventing microbial contamination. Lavender essential oil contributes antioxidant, antimicrobial, and soothing properties that help protect and calm the skin. Shankhpushpi (Convolvulus prostratus) is rich in flavonoids and phenolic compounds that neutralize free radicals, reduce oxidative stress, stimulate skin repair, and delay wrinkle formation. Bael (Aegle marmelos) possesses antioxidant, anti-inflammatory, and antimicrobial phytochemicals that protect collagen, and support healthy youthful skin. Butterfly Pea (Clitoria ternatea) contains anthocyanins that preserve collagen integrity, improve skin firmness, and minimize photoaging. Flaxseed (Linum usitatissimum) is abundant in omega-3 fatty acids and lignans that enhance skin barrier function, promote collagen synthesis, improve elasticity, and reduce fine lines. Orange Peel (Citrus sinensis) provides vitamin C and flavonoids that stimulate collagen production, brighten the complexion, reduce pigmentation, and promote skin renewal. The synergistic combination of these natural ingredients offers antioxidant, moisturizing, anti-inflammatory, collagen-protective, and rejuvenating effects, making herbal peel-off face mask gels a promising, safe, and eco-friendly approach for anti-ageing skincare and future cosmeceutical applications.
