<p><span>Exposure to ultraviolet (UV) radiation is a leading cause of premature skin aging, sunburn, and skin cancer. While conventional sunscreens provide protection, they often contain synthetic ingredients linked to photostability issues, allergic reactions, hormonal disruptions, and potential carcinogenic effects. These limitations have led to growing interest in herbal sunscreens, which offer safer, cost-effective, and eco-friendly alternatives. This review focuses on herbal ingredients with photoprotective properties and minimal side effects, emphasizing their potential in sunscreen formulations.Key herbal components such as shea butter, beeswax, rose water, olive oil, coconut oil, raspberry seed oil, grape seed oil, almond oil, rosehip seed oil, and tea tree oil are rich in flavonoids, phenolic compounds, and essential oils. These ingredients exhibit antioxidant, anti-inflammatory, moisturizing, and skin-rejuvenating properties, contributing to effective UV protection. The photostability of herbal sunscreens is also discussed, highlighting how certain natural compounds stabilize UV filters, ensuring sustained protection.Herbal sunscreens offer multiple advantages, including easy availability, renewable sourcing, low toxicity risks, and no requirement for specialized equipment during preparation. However, challenges such as formulation stability, standardization, and comprehensive clinical validation remain. Addressing these issues through further research could enhance the efficacy and safety profiles of herbal sunscreens. Overall, herbal sunscreens represent a promising, natural alternative to conventional formulations, offering broad-spectrum UV protection with reduced adverse effects.</span></p>
