Figure 1 d-Limonene prevented sunburn formation. Mice were exposed orally to 20 μL of pure or diluted d-limonene daily for 4 consecutive days followed by 1.5 kJ/ m2 of ultraviolet B exposure generated by a commercial sunlamp 1 d later. The maximum sunburn response occurred as shown by skin erythema on 6th day of UVR exposure was completely eliminated by pure d-limonene. A: UVR alone; B: UVR + 1.0% d-limonene in liponate; C: UVR + 10% d-limonene in liponate; D: UVR + 100% d-limonene. Topical application of d-limonene followed by UVR yielded similar results (data not shown). UVR: Ultraviolet irradiation.
