Applied topically, it moisturizes the epidermis, but has no proven anti-aging action, contrary to what the marketing suggests. To make the most of it, apply to damp skin and seal with a cream or SPF.<\/p><div class=\"bd-hero-meta\"><div class=\"bd-hero-meta-item\"><span>Family<\/span><strong>Humectant (polysaccharide)<\/strong><\/div><div class=\"bd-hero-meta-item\"><span>Method<\/span><strong>Verdict Sensitivity - Dr David's rule<\/strong><\/div><div class=\"bd-hero-meta-item\"><span>Selection<\/span><strong>4 treatments rated by BeautyDecoders<\/strong><\/div><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Mode of action<\/span><h2>A humectant <em>powerful<\/em><\/h2><p class=\"bd-lead\">Hyaluronic acid is a humectant: it captures a very large quantity of water, making it the active ingredient of choice for hydration. Naturally present in our bodies (joints, muscles, skin), it plays a role in skin hydration and healing. With age, it diminishes in the dermis, under the effect of sunlight, free radicals and glycation, hence its use in aesthetic injections and cosmetics.<\/p><p class=\"bd-lead\">Its cosmetic benefits include exceptional moisturizing power (one gram attracts over five liters of water), an immediate plumping effect on fine lines, and a non-greasy, non-comedogenic texture. Another advantage is that it is suitable for both dry and oily skin. Along with collagen and elastin, it is one of the three essential components of the dermis, all produced by fibroblasts.<\/p><div class=\"bd-video-wrap\"><iframe src=\"https:\/\/www.youtube.com\/embed\/49gGdDmLC1A\" title=\"Hyaluronic acid explained - BeautyDecoded\" loading=\"lazy\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Scientific reality<\/span><h2>What he does <em>really<\/em><\/h2><p class=\"bd-lead\">In cream or serum form, hyaluronic acid does not penetrate to the dermis, but remains in the epidermis. Most products use molecules of different weights: the larger ones act on the surface, while the smaller ones penetrate a little deeper into the epidermis, without ever reaching the dermis.<\/p><p class=\"bd-lead\">What's more, hyaluronic acid is continually created and destroyed in the body: an enzyme, hyaluronidase, breaks it down in 24 to 48 hours. This is why the effect of a serum lasts 24 to 48 hours. Discovered in 1934 and widely studied, hyaluronidase has a solid track record in wound healing and aesthetic medicine, but little data on its anti-ageing effect when applied topically. A study of users on isotretinoin (suffering from severe dryness) showed that a hyaluronic acid cream significantly improved dryness and acne, but beyond that, evidence of a topical anti-aging effect is lacking.<\/p><div class=\"bd-alert bd-alert-info\"><span class=\"bd-alert-icon\">\ud83d\udc89<\/span><div>In aesthetic medicine, injected hyaluronic acid is stabilized and cross-linked: bridges between the chains slow down its resorption (six months to a year and a half). It is injected into the dermis for texture, or subcutaneously to restore volume (cheekbones, lips, dark circles, nose). These procedures require specialized medical consultation.<\/div><\/div><\/div><\/section><section class=\"bd-dark\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Focusing<\/span><h2>The anti-aging myth <em>topical application<\/em><\/h2><p>Why has hyaluronic acid become one of marques's favorite active ingredients? For its real qualities (hydration, tolerance, immediate action), but also because the industry has long played on the confusion between the effect of injections and that of local application.<\/p><div class=\"bd-dark-quote\"><strong>An excellent moisturizer, not an anti-aging agent<\/strong><p>This confusion gives the impression of a topical anti-aging effect, to the detriment of actives that really have one, such as retinol, but whose use is more complex. Hyaluronic acid remains an excellent moisturizer - it is not an anti-aging active.<\/p><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Tolerance<\/span><h2>Can it cause <em>reactions<\/em> ?<\/h2><p class=\"bd-lead\">Yes, but rarely in cosmetics on healthy skin. In hospitals, on wounds (with an altered skin barrier), some users developed reactions after ten days or so. In cosmetics, unusual redness may indicate poor tolerance to the very fine molecules of hyaluronic acid (potentially pro-inflammatory) or to another ingredient in the product. The right reflex: don't insist on using the product in question, try others before banishing hyaluronic acid, and stick to a simple routine to limit risks.<\/p><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Instructions for use<\/span><h2>How to <em>use it<\/em><\/h2><p class=\"bd-lead\">It all depends on the format. A moisturizing cream often contains other humectants (glycerin), emollients and occlusives: no particular precautions are required, other than to apply it to slightly damp skin to maximize the effect. On the other hand, a serum containing only humectants, with no emollients or occlusives, can dry out the skin: the water attracted eventually evaporates. So always seal with a cream or sun cream containing emollients or occlusives. Exception: in very humid climates, hyaluronic acid draws water from the air, so an occlusive is optional.<\/p><div class=\"bd-alert bd-alert-info\"><span class=\"bd-alert-icon\">\u26a0<\/span><div>If you use a hyaluronic acid serum in the evening, do not apply a retinol serum immediately afterwards on damp skin: this enhances the penetration of the retinol, which will act more strongly and may cause irritation.<\/div><\/div><\/div><\/section><!-- ===== S\u00c9LECTION PRODUITS ===== --><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">The selection<\/span><h2>Hyaluronic acid products <em>choose<\/em> ?<\/h2><p class=\"bd-lead\">Here's a selection by format (lotion, serum, moisturizing sunscreen), with BeautyDecoded scores and user feedback.

Pure hyaluronic acid serum, on the other hand, can encourage water evaporation and dry out the skin.<\/div><\/details><details class=\"bd-faq-item\"><summary>Hyaluronic acid for oily or dry skin?<\/summary><div class=\"bd-faq-answer\">Both: that's one of its great assets. Non-comedogenic and non-greasy, it's suitable for oily skin; highly moisturizing, it soothes dry skin. The only thing that changes is the routine that surrounds it (richer or less rich cream to seal in moisture).<\/div><\/details><details class=\"bd-faq-item\"><summary>Can hyaluronic acid and retinol be combined?<\/summary><div class=\"bd-faq-answer\">Yes, hyaluronic acid even helps moisturize skin dried out by retinol. Just avoid applying retinol immediately after a hyaluronic acid serum on damp skin, as this intensifies retinol penetration and the risk of irritation.<\/div><\/details><details class=\"bd-faq-item\"><summary>How long does a serum last?<\/summary><div class=\"bd-faq-answer\">The moisturizing and plumping effect lasts 24 to 48 hours, as hyaluronic acid is broken down by a natural enzyme, hyaluronidase. This is why it should be used daily, as part of a regular routine, for continuous benefits.<\/div><\/details><\/div><\/div><\/section><section class=\"bd-section\"><div class=\"bd-wrap\"><span class=\"bd-section-label\">Further information<\/span><h2>Others <em>associated guides<\/em><\/h2><div class=\"bd-hub-grid\"><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/retinol\/\"><span class=\"bd-hub-card-tag\">Ingredient<\/span><h3>Retinol<\/h3><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/vitamin-c\/\"><span class=\"bd-hub-card-tag\">Ingredient<\/span><h3>Vitamin C<\/h3><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/moisturizer\/\"><span class=\"bd-hub-card-tag\">Guide<\/span><h3>How to moisturize your skin<\/h3><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/care-by-skin-type\/dry-skin\/\"><span class=\"bd-hub-card-tag\">Guide<\/span><h3>Dry skin<\/h3><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><\/div><\/div><\/section><div class=\"bd-sig\"><strong>Dr Sylvain David<\/strong><span>Plastic and aesthetic surgeon - Founder of BeautyDecoded<\/span><\/div><div class=\"bd-disclaimer\"><p>Information for educational purposes only.
