Abstract
Many studies performed in the last decade have focused on the cutaneous microbiota. It has been shown that this microbiota plays a key role in skin homeostasis. Considered as “a second barrier” to the environment, it is very important to know how it reacts to exogenous aggressions. The cosmetics industry has a started to use this microbiota as a source of natural ingredients, particularly ones that confer photoprotection against ultraviolet (UV) rays. Interestingly, it has been demonstrated that bacterial molecules can block UV rays or reverse their harmful effects. Oral probiotics containing living microorganisms have also shown promising results in restoring skin homeostasis and reversing the negative effects of UV rays. Microbial-based active sunscreen compounds have huge potential for use as next-generation photoprotection products.

Abstract
BACKGROUND Erythropoietic protoporphyria (EPP) is a rare metabolic disorder, characterized by photosensitivity, caused by errors of the haem biosynthetic pathway. Avoidance of sun exposure is recommended; however, some patients suggested a paradoxical improvement of symptoms when they move to sunny areas. OBJECTIVES In a national French study, we sought to investigate the influence of sun exposure on EPP symptoms. MATERIALS AND METHODS We used a national transversal observational study by questionnaire. Patients were selected from the national record of the Centre Français des Porphyries (French Porphyrias referral centre). Sun exposure level by geographic area was assessed using climate data provided by the French national meteorological service (Météo France). RESULTS Eighty-nine patients were included. We notably observed that 40% of patients declared an improvement in their tolerance of sun exposure after repeated sun exposures. In the more sunny areas, the intensity of the pain was lower (r = -0·26) and the duration of the sun exposure responsible for flares was longer (r = 0·39) than in the areas that were less sunny (P < 0·05). CONCLUSIONS This study proposes a benefit of natural progressive sun exposure for patients with EPP.
