If necessary, an oral treatment with antihistamines or anti-inflammatory medication may be prescribed. In the rare cases where the reaction is more pronounced, an injection of hyaluronidase may be performed : this enzyme dissolves hyaluronic acid and makes it possible to immediately correct the effect of the product.<br data-start=\"846\" data-end=\"849\">Medical monitoring remains essential to ensure a favorable outcome. One of the major advantages of hyaluronic acid is precisely its reversibility : in the event of intolerance or an undesirable result, it is always possible to intervene and safely restore the balance of the face.<\/p>\n<h2>Conclusion<\/h2>\n<p class=\"translation-block\">Allergy to hyaluronic acid is extremely rare. The molecule is natural, biocompatible and resorbable. Mild reactions are common, but transient and without severity. In the event of persistent pain, significant inflammation or an unusual reaction, it is imperative to consult the physician.<br>A thorough medical history, a rigorous product selection and a well-controlled technique help to minimize risks.<\/p>\n<p>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/07\/photo-docteur-romano-valeria-150x150.webp\" alt=\"Photo of doctor Valeria Romano in Geneva\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/p>\n<p>Article written by <a href=\"https:\/\/drromanovaleria.ch\/en\/\">Dr Romano Valeria<\/a><\/p>\n<p>SHARE THIS ARTICLE ON<\/p>\n<p>\t\t\t\t\t\t\t\t<svg aria-hidden=\"true\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 32H31.9C14.3 32 0 46.5 0 64.3v383.4C0 465.5 14.3 480 31.9 480H416c17.6 0 32-14.5 32-32.3V64.3c0-17.8-14.4-32.3-32-32.3zM135.4 416H69V202.2h66.5V416zm-33.2-243c-21.3 0-38.5-17.3-38.5-38.5S80.9 96 102.2 96c21.2 0 38.5 17.3 38.5 38.5 0 21.3-17.2 38.5-38.5 38.5zm282.1 243h-66.4V312c0-24.8-.5-56.7-34.5-56.7-34.6 0-39.9 27-39.9 54.9V416h-66.4V202.2h63.7v29.2h.9c8.9-16.8 30.6-34.5 62.9-34.5 67.2 0 79.7 44.3 79.7 101.9V416z\"><\/path><\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\tLinkedIn\t\t\t\t\t\t\t\t\t<\/p>\n<ul>\n<li>\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"mailto:dr.romano.valeria@gmail.com\"><br \/>\n\t\t\t\t\t\t\t<svg aria-hidden=\"true\" viewbox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M502.3 190.8c3.9-3.1 9.7-.2 9.7 4.7V400c0 26.5-21.5 48-48 48H48c-26.5 0-48-21.5-48-48V195.6c0-5 5.7-7.8 9.7-4.7 22.4 17.4 52.1 39.5 154.1 113.6 21.1 15.4 56.7 47.8 92.2 47.6 35.7.3 72-32.8 92.3-47.6 102-74.1 131.6-96.3 154-113.7zM256 320c23.2.4 56.6-29.2 73.4-41.4 132.7-96.3 142.8-104.7 173.4-128.7 5.8-4.5 9.2-11.5 9.2-18.9v-19c0-26.5-21.5-48-48-48H48C21.5 64 0 85.5 0 112v19c0 7.4 3.4 14.3 9.2 18.9 30.6 23.9 40.7 32.4 173.4 128.7 16.8 12.2 50.2 41.8 73.4 41.4z\"><\/path><\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\tdr.romano.valeria@gmail.com<br \/>\n\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/li>\n<li>\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"tel:+41%2078%20209%2002%2089\"><br \/>\n\t\t\t\t\t\t\t<svg aria-hidden=\"true\" viewbox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M497.39 361.8l-112-48a24 24 0 0 0-28 6.9l-49.6 60.6A370.66 370.66 0 0 1 130.6 204.11l60.6-49.6a23.94 23.94 0 0 0 6.9-28l-48-112A24.16 24.16 0 0 0 122.6.61l-104 24A24 24 0 0 0 0 48c0 256.5 207.9 464 464 464a24 24 0 0 0 23.4-18.6l24-104a24.29 24.29 0 0 0-14.01-27.6z\"><\/path><\/svg><br \/>\n\t\t\t\t\t\t\t\t\t\t+41 78 209 02 89<br \/>\n\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/li>\n<\/ul>","protected":false},"featured_media":5444,"template":"elementor_header_footer","class_list":["post-24758","infographie","type-infographie","status-publish","has-post-thumbnail","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Peut-on \u00eatre allergique \u00e0 l\u2019acide hyaluronique ? - Dr Romano<\/title>\n<meta name=\"description\" content=\"Les r\u00e9actions allergiques \u00e0 l\u2019acide hyaluronique sont rares, car il s\u2019agit d\u2019une substance naturellement pr\u00e9sente dans le corps.
