Many patients wonder: why does this product, naturally present in the human body, not stay in place permanently? Hyaluronic acid's non-permanent nature is neither a weakness nor a constraint, but a fundamental property contributing to its safety and clinical relevance.<\/p>\n<p>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"419\" src=\"https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/06\/skinbooster-rides-joues-2-768x419.webp\" alt=\"photo cheek wrinkle treatment with skinbooster\" srcset=\"https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/06\/skinbooster-rides-joues-2-768x419.webp 768w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/06\/skinbooster-rides-joues-2-300x164.webp 300w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/06\/skinbooster-rides-joues-2-1024x559.webp 1024w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/06\/skinbooster-rides-joues-2-1536x838.webp 1536w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/06\/skinbooster-rides-joues-2-2048x1117.webp 2048w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/06\/skinbooster-rides-joues-2-18x10.webp 18w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><br \/>\n\t\t\t\t\t<a href=\"https:\/\/drromanovaleria.ch\/en\/contact-doctor-romano-valeria\/\"><br \/>\n\t\t\t\t\t\t\t\t\tBook an appointment<br \/>\n\t\t\t\t\t<\/a><\/p>\n<h2>\n\t\t\t\tContents\t\t\t<\/h2>\n<p>\t\t\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=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><br \/>\n\t\t\t\t<svg aria-hidden=\"true\" viewbox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M240.971 130.524l194.343 194.343c9.373 9.373 9.373 24.569 0 33.941l-22.667 22.667c-9.357 9.357-24.522 9.375-33.901.04L224 227.495 69.255 381.516c-9.379 9.335-24.544 9.317-33.901-.04l-22.667-22.667c-9.373-9.373-9.373-24.569 0-33.941L207.03 130.525c9.372-9.373 24.568-9.373 33.941-.001z\"><\/path><\/svg><br \/>\n\t\t\t\t<svg aria-hidden=\"true\" viewbox=\"0 0 1000 1000\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M500 975V858C696 858 858 696 858 500S696 142 500 142 142 304 142 500H25C25 237 238 25 500 25S975 237 975 500 763 975 500 975Z\"><\/path><\/svg>\t\t\t<\/p>\n<h2>What is hyaluronic acid ?<\/h2>\n<p>Hyaluronic acid is a physiological molecule present in many tissues of the human body, particularly the skin, joints and eyes. Its main role is to retain water, maintain hydration and contribute to tissue suppleness.<br \/>Unlike an inert substance, hyaluronic acid is constantly synthesised and broken down by the body. This partly explains why injectable hyaluronic acid cannot be permanent: the body is naturally programmed to metabolise it.<br \/>The injectable gels used in aesthetic medicine are designed to mimic this natural molecule, but are slightly modified to prolong their action. However, they remain subject to the same biological breakdown mechanisms.<\/p>\n<h2>Variable duration of effects<\/h2>\n<p>The duration of hyaluronic acid effects is never strictly predictable and depends on several factors. Depending on these factors, effects may last from a few months to more than a year, but gradual absorption is the rule, never the exception.<\/p>\n<ul>\n<li>The type of gel: highly cross-linked (deep volumiser) or very fluid (superficial, Skinbooster).<\/li>\n<li>The injected area: in highly mobile regions, the product breaks down faster than in less mobile areas.<\/li>\n<li>Individual metabolism: some people naturally break down hyaluronic acid faster than others.<\/li>\n<\/ul>\n<h2>Cross-linking: prolonging the effect without making it permanent<\/h2>\n<p>To increase the duration of injectable hyaluronic acid, manufacturers have developed cross-linking processes. This chemical modification makes the molecule more resistant to enzymatic degradation.<br \/>The more cross-linked the gel, the denser it is and the longer its action lasts. However, even the most highly cross-linked hyaluronic acids remain biodegradable. No injectable hyaluronic acid gel is designed to remain in tissues indefinitely.<br \/>This is a deliberate choice. Making a product permanent would considerably increase long-term risks, particularly if the face changes, complications arise or the indication changes.<\/p>\n<h2>The face changes, so treatments must be adaptable<\/h2>\n<p>The human face is not a fixed structure. It changes over time through ageing, weight fluctuations, hormonal changes and numerous environmental factors.<br \/>A permanent product would fix the face in a given state without allowing adaptation. Conversely, hyaluronic acid's temporary nature allows volumes to be adjusted over time, the treatment strategy to be modified and natural facial changes to be respected.<br \/>Gradual product absorption provides essential treatment flexibility for both patient and doctor.<\/p>\n<h2>Medical safety associated with non-permanence<\/h2>\n<p data-pm-slice=\"1 1 []\">Hyaluronic acid stands out for its high safety profile, widely recognised in aesthetic medicine. Its biodegradable nature allows gradual, natural absorption by the body without permanent sequelae.<br \/>This provides additional safety for patients: if results do not meet expectations, aesthetic goals change or the face naturally evolves, results can be adjusted or disappear over time. Reversibility is therefore a major advantage compared with previously used permanent products, whose long-term complications led to their abandonment.<\/p>\n<p>By avoiding permanent change, hyaluronic acid protects patients over time and forms part of a modern, cautious and responsible approach to aesthetic medicine.<\/p>\n<h2>Permanent products of the past<\/h2>\n<p>Historically, permanent injectable products were used in aesthetic medicine. Their use was gradually abandoned because of delayed complications: chronic inflammatory reactions, nodules, migration and difficulties with subsequent management.<br \/>These experiences profoundly influenced medical practice and led to a major evolution in safety standards. Today, non-permanence is considered a fundamental quality criterion for an injectable product.<\/p>\n<h2>Why gradual product disappearance is an aesthetic advantage<\/h2>\n<p>Aesthetically, gradual hyaluronic acid absorption allows a more natural result. The face undergoes no abrupt change, but a gentle evolution consistent with ageing.<br \/>This timing allows frozen effects to be avoided, facial dynamics to be preserved, overall harmony to be maintained and facial identity to be respected<br \/>Treatment thus becomes ongoing support rather than a permanent transformation.<\/p>\n<p>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"252\" height=\"300\" src=\"https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/07\/photo-docteur-romano-valeria-252x300.webp\" alt=\"Photo of doctor Valeria Romano in Geneva\" srcset=\"https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/07\/photo-docteur-romano-valeria-252x300.webp 252w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/07\/photo-docteur-romano-valeria-10x12.webp 10w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/07\/photo-docteur-romano-valeria.webp 763w\" sizes=\"auto, (max-width: 252px) 100vw, 252px\" \/>\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},"excerpt":{"rendered":"<p>Hyaluronic acid is not permanent because it is naturally reabsorbed by the body.
