Les spicules sont microscopiques en forme d'aiguille<\/a> Ces structures sont souvent d\u00e9riv\u00e9es d'organismes marins ou de sources synth\u00e9tiques. Ils sont utilis\u00e9s dans les soins de la peau pour cr\u00e9er des micro-canaux contr\u00f4l\u00e9s dans la peau.<\/p>\n Lorsqu'elles sont appliqu\u00e9es localement, les spicules p\u00e9n\u00e8trent dans les couches sup\u00e9rieures de la peau, augmentant le renouvellement cellulaire et am\u00e9liorant la p\u00e9n\u00e9tration des ingr\u00e9dients actifs. Cela cr\u00e9e un effet de resurfa\u00e7age similaire au concept de microneedling<\/a>\u00a0mais par le biais d'un produit topique.<\/p>\n Les spicules peuvent am\u00e9liorer la texture et la luminosit\u00e9, mais ils ne constituent pas un ingr\u00e9dient \u00e0 usage quotidien et ne doivent pas \u00eatre superpos\u00e9s \u00e0 d'autres actifs agressifs. Utilis\u00e9s trop fr\u00e9quemment ou de mani\u00e8re incorrecte, ils peuvent compromettre l'efficacit\u00e9 du produit. barri\u00e8re cutan\u00e9e<\/a>. Les spicules conviennent mieux \u00e0 des traitements de courte dur\u00e9e ou \u00e0 des routines guid\u00e9es par des professionnels qu'\u00e0 une utilisation \u00e0 long terme sans surveillance.<\/p>","protected":false},"excerpt":{"rendered":" What they are Spicules are microscopic needle-like structures, often derived from marine organisms or synthetic…<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_relevanssi_hide_post":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","footnotes":"","_links_to":"","_links_to_target":""},"doc_category":[],"glossaries":[],"doc_tag":[],"class_list":["post-2010002","docs","type-docs","status-publish"],"acf":[],"year_month":"2026-06","word_count":119,"total_views":"355","reactions":{"happy":"0","normal":"0","sad":"0"},"author_info":{"name":"freshpies","author_nicename":"freshpies","author_url":"https:\/\/www.dralexisgranite.com\/fr\/author\/freshpies\/"},"doc_category_info":[],"doc_tag_info":[],"knowledge_base_info":[],"knowledge_base_slug":[],"_links":{"self":[{"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/docs\/2010002","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/docs"}],"about":[{"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/types\/docs"}],"author":[{"embeddable":true,"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/comments?post=2010002"}],"version-history":[{"count":0,"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/docs\/2010002\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/media?parent=2010002"}],"wp:term":[{"taxonomy":"doc_category","embeddable":true,"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/doc_category?post=2010002"},{"taxonomy":"glossaries","embeddable":true,"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/glossaries?post=2010002"},{"taxonomy":"doc_tag","embeddable":true,"href":"https:\/\/www.dralexisgranite.com\/fr\/wp-json\/wp\/v2\/doc_tag?post=2010002"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Comment ils agissent dans les soins de la peau<\/h3>\n
