It represents around 75 % of the skin's dry weight and is a fundamental component of the dermis. Its function is to give the skin firmness, mechanical strength and elasticity. In a young person, collagen fibres are abundant, well organised and associated with elastin and hyaluronic acid, allowing smooth, toned, wrinkle-free skin.<br \/>Several collagen types exist, but those playing a major role in skin health are mainly type I collagen, abundant in the deep dermis, and type III collagen, essential to tissue suppleness. Until around 25, the skin renews these structural fibres optimally. Thereafter, collagen production gradually decreases while its breakdown accelerates, leading to loss of firmness and elasticity over time.<\/p>\n<p>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"220\" src=\"https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/05\/hydratation-peau.webp\" alt=\"image of young hydrated skin\" srcset=\"https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/05\/hydratation-peau.webp 300w, https:\/\/drromanovaleria.ch\/wp-content\/uploads\/2024\/05\/hydratation-peau-16x12.webp 16w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><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>Pourquoi la production de collag\u00e8ne diminue-t-elle avec l&rsquo;\u00e2ge ?<\/h2>\n<p>Avec l\u2019\u00e2ge, la production de collag\u00e8ne diminue progressivement, d\u00e8s la vingtaine, \u00e0 un rythme estim\u00e9 entre 1 % et 1,5 % par an. Ce ph\u00e9nom\u00e8ne s\u2019acc\u00e9l\u00e8re apr\u00e8s 40 ans et peut \u00eatre aggrav\u00e9 par des facteurs environnementaux tels que l\u2019exposition aux rayons UV, la pollution, le stress oxydatif, le tabagisme et une alimentation d\u00e9s\u00e9quilibr\u00e9e. La qualit\u00e9 des fibres de collag\u00e8ne se d\u00e9t\u00e9riore \u00e9galement : elles deviennent plus rigides, d\u00e9sorganis\u00e9es, et leur capacit\u00e9 \u00e0 maintenir la structure de la peau s&rsquo;affaiblit.<br \/>This gradual collagen deterioration is directly linked to visible signs of skin ageing, particularly fine lines, deep wrinkles and facial laxity. Loss of dermal density makes the skin thinner, less elastic and more susceptible to gravity.<\/p>\n<h2>Comment la perte de collag\u00e8ne favorise-t-elle l&rsquo;apparition des rides ?<\/h2>\n<p>Wrinkles are the morphological reflection of disorganisation in dermal connective tissue. They first appear as fine dynamic lines linked to muscle contraction. With time and declining collagen, these lines become permanent and deepen. Several wrinkle types can be distinguished :<\/p>\n<ul>\n<li>Expression lines, linked to muscle activity (crow's feet, forehead lines, frown lines).<\/li>\n<li>Gravitational wrinkles, caused by loss of support in the dermis and fatty tissue (nasolabial folds and marionette lines, for example).<\/li>\n<li>Actinic wrinkles, resulting from chronic sun exposure and closely linked to UV-induced collagen degradation.<\/li>\n<\/ul>\n<h2>Which factors accelerate collagen loss in the skin ?<\/h2>\n<p>Beyond chronological ageing, many environmental and behavioural factors accelerate collagen loss and therefore premature wrinkle formation. These external factors must be considered in any facial rejuvenation strategy.<br \/>These factors justify targeted dermal treatments, such as facial mesotherapy and Skinbooster injections, which not only stimulate collagen production but also restore skin quality damaged by external stressors.<\/p>\n<ul>\n<li>Sun exposure : ultraviolet (UV) radiation, particularly UVA, penetrates deep into the dermis and damages collagen fibres. It activates production of matrix metalloproteinases (MMPs), enzymes that break down dermal supporting fibres. This process, called photoageing, is one of the main causes of early wrinkles, particularly on the face, neck and d\u00e9colletage.<\/li>\n<li>Smoking : regular smoking causes constriction of dermal capillaries, reducing the supply of oxygen and essential nutrients to fibroblasts. Cigarette smoke also contains free radicals that destroy structural proteins such as collagen and elastin. Smokers' skin is often duller, dehydrated and prematurely aged.<\/li>\n<li>Oxidative stress and pollution : urban pollution and fine particles generate chronic oxidative stress in the skin. This stimulates free radicals that attack cell membranes and matrix proteins such as collagen. Chronic oxidative stress worsens skin laxity and deep wrinkle formation.<\/li>\n<li>Diet and lifestyle : an unbalanced diet low in antioxidants (vitamins C and E, polyphenols), amino acids and essential fatty acids impairs the body's collagen synthesis. Conversely, a sugar-rich diet encourages glycation of collagen fibres, making them stiff. This glycation process is particularly visible in mature skin lacking elasticity.<\/li>\n<\/ul>\n<h2>How can collagen be preserved to prevent wrinkles ?<\/h2>\n<p>Preserving collagen is a fundamental pillar of skin ageing prevention. A comprehensive strategy based on simple but essential habits slows wrinkle formation and maintains skin firmness and elasticity over time. Daily sun protection with SPF 50+ remains the first defence against UV-induced collagen degradation. A balanced diet rich in antioxidants, omega-3 fatty acids and amino acids also plays a major role, nourishing the skin from within. Adequate hydration, both of the skin and the body, is essential too. Limiting aggravating factors such as smoking and oxidative stress, which accelerate ageing, is equally crucial. Finally, regular topical skincare, such as vitamin C or retinol, naturally stimulates collagen production and improves skin quality. Combined with non-invasive medical treatments performed in the practice, these habits provide a comprehensive, lasting and effective approach to preserving youthful skin.<\/p>\n<h2>Which treatments naturally stimulate collagen production ?<\/h2>\n<p data-start=\"153\" data-end=\"811\">In a modern, precise and personalised approach to wrinkle treatment, stimulating collagen synthesis now plays a central role. In Geneva, advanced aesthetic techniques activate neocollagenesis \u2014 the production of new collagen \u2014 to redensify the dermis, smooth wrinkles and restore skin elasticity, all without surgery. Protocol selection always rests on a comprehensive, individual assessment : age, skin quality, ageing pattern and patient expectations guide the choice of the most appropriate treatments.<\/p>\n<h3>Is Sculptra the best treatment for stimulating collagen ?<\/h3>\n<p>Sculptra is an injectable collagen stimulator whose active ingredient is poly-L-lactic acid. Unlike conventional fillers, its action is not immediate : it gradually stimulates fibroblast activity to rebuild skin structure from within. Subtle but lasting results emerge over the weeks. This treatment is particularly indicated for hollow faces, deep folds or prevention of age-related laxity.<\/p>\n<h3>Do Skinboosters really stimulate collagen production ?<\/h3>\n<p data-start=\"220\" data-end=\"806\">Skinboosters are lightly cross-linked hyaluronic acid injections designed to improve overall skin quality. Their action follows two complementary pathways : deep rehydration, restoring tissue radiance and suppleness, and stimulation of collagen synthesis triggered by the mechanical effect of injections. This treatment is particularly intended for thin or dehydrated skin, as well as skin beginning to show the first signs of laxity and ageing, providing freshness, firmness and vitality.<\/p>\n<h3>Can mesolift stimulate skin collagen ?<\/h3>\n<p>Mesolift involves intradermal injections of a nourishing complex of non-cross-linked hyaluronic acid, vitamins, amino acids and trace elements. By revitalising the cellular environment, it restarts fibroblast activity and improves skin quality, firmness and radiance. It is particularly indicated for dull, depleted or fragile skin.<\/p>\n<h3>Does fractional laser stimulate collagen production ?<\/h3>\n<p>Fractional ablative laser creates thermal microperforations in the dermis, stimulating an intense repair response. This technique produces deep collagen restructuring and visible skin renewal. It is ideal for pronounced wrinkles, uneven skin density, enlarged pores or mature skin losing firmness.<\/p>\n<h3>Is laser photorejuvenation effective for restarting collagen production ?<\/h3>\n<p>Unlike intense pulsed light, laser photorejuvenation has a more targeted, powerful action on the deep dermis. It triggers controlled thermal stimulation, activating collagen synthesis and gradually improving skin density. Alongside this, treatment corrects certain pigmentation or vascular irregularities while reviving complexion radiance. It is particularly suited to ageing prevention or skin maintenance.<\/p>\n<h2>Quels r\u00e9sultats attendre d&rsquo;un traitement stimulant le collag\u00e8ne ?<\/h2>\n<p>Aesthetic medicine treatments focused on stimulating collagen synthesis offer many benefits for patients wishing to address wrinkles naturally and gradually : overall improvement in skin quality, a visible tightening effect after a few weeks, gradual reduction in superficial and moderate wrinkles, delayed need for more invasive procedures and a natural result without facial 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=\"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":0,"template":"elementor_header_footer","class_list":["post-25953","infographie","type-infographie","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Quel est le r\u00f4le du collag\u00e8ne dans la formation des rides ?
