Beta-carotene is discussed to protect against photooxidative stress and thus prevent skin damage. Though beta-carotene has been successfully used against photosensitivity in patients with erythropoietic protoporphyria, its beneficial potential in normal skin is still uncertain. A number of experimental studies indicate protective effects of beta-carotene against acute and chronic manifestations of skin photodamage. However, most clinical studies have failed to convincingly demonstrate its beneficial effects so far. Nevertheless, intake of oral beta-carotene supplements before sun exposure has been recommended on a population-wide basis. Recent studies on skin cells in culture have revealed that beta-carotene acts not only as an antioxidant but also has unexpected prooxidant properties. At present, there is an ongoing debate on the protective or potentially harmful role of beta-carotene in human skin.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56598","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"BIESALSKI HK,UNIV HOHENHEIM,DEPT BIOL CHEM & NUTR;FRUWIRTHSTR 12;D-70593 STUTTGART, GERMANY.biesal@uni-hohenheim.de\"","annee":"2001","mois":"5","numero":"389:1","page":"1-6","auteurs":[{"ID":56597,"post_author":"0","post_date":"2018-12-04 07:25:45","post_date_gmt":"2018-12-04 06:25:45","post_content":"","post_title":"Obermueller Jevic","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"obermueller-jevic","to_ping":"","pinged":"","post_modified":"2018-12-04 07:25:45","post_modified_gmt":"2018-12-04 06:25:45","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/obermueller-jevic\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":2641,"post_author":"0","post_date":"2018-12-03 16:57:41","post_date_gmt":"2018-12-03 15:57:41","post_content":"","post_title":"Hans Konrad Biesalski","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"hans-konrad-biesalski","to_ping":"","pinged":"","post_modified":"2018-12-03 16:57:41","post_modified_gmt":"2018-12-03 15:57:41","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/hans-konrad-biesalski\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":5122,"post_author":"0","post_date":"2018-12-03 17:24:29","post_date_gmt":"2018-12-03 16:24:29","post_content":"","post_title":"ARCHIVES OF BIOCHEMISTRY AND BIOPHYSICS","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"archives-of-biochemistry-and-biophysics","to_ping":"","pinged":"","post_modified":"2018-12-03 17:24:29","post_modified_gmt":"2018-12-03 16:24:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/archives-of-biochemistry-and-biophysics\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
