Sunscreens in Patients With Cutaneous Lupus Erythematosus(CLE)
Part I: to investigate the efficacy of different sunscreens in the prevention of skin lesions following standardized photoprovocation with Ultraviolet A/Ultraviolet B (UVA/UVB) light in patients with CLE.
Part II: to evaluate the influence of different sunscreens on the expression of biomarkers in the skin of patients with CLE and of Healthy Controls following UV irradiation.

Part I-interventions will be:
- Experimental intervention: Application of broad-spectrum sunscreens with a low, medium, and high Sun Protection Factor (SPF) in random order to uninvolved skin areas prior to standardized photoprovocation.
- Control intervention: Intra-individual application of vehicle in random order; standardized photoprovocation of vehicle treated and untreated areas.
Part II-interventions will be:
- Experimental intervention: Application of a broad-spectrum sunscreen with a high SPF to uninvolved skin areas prior to UV irradiation.
- Control intervention: UV irradiation of untreated areas.
