Abstract: The growing concerns over the adverse effects of prolonged exposure to ultraviolet (UV) radiation, coupled with increasing reports of skin irritation, environmental contamination, and potential endocrine-disrupting effects associated with synthetic sunscreen ingredients, have intensified interest in plant-based alternatives for photoprotection. This review gives an insight to the dermatological and photoprotective potential of three widely utilized medicinal plants, Moringa oleifera, Curcuma longa, and Aloe vera, with emphasis on their phytochemical composition, mechanisms of action, and applications in topical skincare and cosmeceutical formulations. Relevant literature was critically evaluated using peer-reviewed sources. Evidence from the reviewed studies indicates that these plants contain diverse bioactive compounds, including flavonoids, phenolic acids, carotenoids, curcuminoids, polysaccharides, vitamins, and other antioxidants that contribute to skin protection through multiple mechanisms. These mechanisms include direct absorption of ultraviolet radiation, neutralization of reactive oxygen species, suppression of inflammatory pathways, enhancement of skin barrier function, stimulation of collagen synthesis, and promotion of wound healing. The review further highlights the benefits of combining these botanicals in topical formulations, where improvements in photoprotective efficacy, antioxidant capacity, skin hydration, and formulation stability have been reported. Recent advances in extraction technologies and delivery systems have also enhanced the bioavailability and effectiveness of plant-derived photoprotective agents. Collectively, the evidence demonstrates that Moringa oleifera, Curcuma longa, and Aloe vera possess considerable potential as sustainable and multifunctional ingredients for dermatological and cosmeceutical applications. However, further clinical investigations, formulation optimization, and long-term safety evaluations are required to fully establish their effectiveness as alternatives or complements to conventional synthetic photoprotective agents.
