The marketing surrounding this ingredient is such that it seems logical to believe it. However, the science is very different. Here's why glycerine is often preferable, and how to read an INCI list to choose a good moisturizing product.<\/p>\n      <div class=\"bd-callout\">This content is for information and educational purposes only. It does not constitute medical advice, and recommendations must be adapted to each individual. The application <strong>BeautyDecoded<\/strong> analyzes INCI formulations using artificial intelligence to identify the right cosmetics for each skin type.<\/div>\n    <\/div>\n  <\/section>\n\n  <!-- ============ CONFUSION HA ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap-narrow\">\n      <div class=\"bd-section-label\">The myth<\/div>\n      <h2>Maintaining confusion <em>around hyaluronic acid<\/em>.<\/h2>\n      <p class=\"bd-prose\">The cosmetics industry plays on the confusion between two very different things: the <strong>injections<\/strong> of hyaluronic acid, performed by a physician in the dermis, and the\u2019<strong>local application<\/strong> of hyaluronic acid in a cream or serum. This confusion leads us to believe that the anti-aging effects of cosmetic application are spectacular, which is inaccurate: a surface-applied humectant does not have the same mechanism as an injected filler.<\/p>\n      <p class=\"bd-prose\">However, products containing hyaluronic acid are not bad (except for allergies). The point is not to demonize them, but to put a bit of science back into the equation: there are other humectants that are at least as interesting, and sometimes even more so.<\/p>\n    <\/div>\n  <\/section>\n\n  <!-- ============ 500 DALTONS ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap-narrow\">\n      <div class=\"bd-section-label\">The science<\/div>\n      <h2>The 500-dalton rule <em>and molecular weight<\/em>.<\/h2>\n      <p class=\"bd-prose\">Humectants are molecules that attract water and moisturize the skin. Their molecular weight counts for a lot: in cosmetics, the <strong>\u00ab500-dalton rule\u00bb<\/strong> is that above a weight of 500, a molecule has great difficulty penetrating the skin barrier. This is not an absolute law (other criteria come into play), but a good benchmark.<\/p>\n      <div class=\"bd-mwtable\">\n        <div class=\"bd-mwrow bd-mwhead\">\n          <div class=\"bd-mwcell\">Humectant<\/div>\n          <div class=\"bd-mwcell\">Molecular weight<\/div>\n          <div class=\"bd-mwcell\">Special features<\/div>\n        <\/div>\n        <div class=\"bd-mwrow bd-hl\">\n          <div class=\"bd-mwcell bd-mwname\">Glycerine<\/div>\n          <div class=\"bd-mwcell bd-mwval\">92<\/div>\n          <div class=\"bd-mwcell\">Reference humectant, penetrates deep layers<\/div>\n        <\/div>\n        <div class=\"bd-mwrow\">\n          <div class=\"bd-mwcell bd-mwname\">Urea<\/div>\n          <div class=\"bd-mwcell bd-mwval\">60<\/div>\n          <div class=\"bd-mwcell\">NMF; high concentration keratolytic<\/div>\n        <\/div>\n        <div class=\"bd-mwrow\">\n          <div class=\"bd-mwcell bd-mwname\">Lactic acid<\/div>\n          <div class=\"bd-mwcell bd-mwval\">90<\/div>\n          <div class=\"bd-mwcell\">NMF; also gentle exfoliant (AHA)<\/div>\n        <\/div>\n        <div class=\"bd-mwrow\">\n          <div class=\"bd-mwcell bd-mwname\">Panthenol (provitamin B5)<\/div>\n          <div class=\"bd-mwcell bd-mwval\">205<\/div>\n          <div class=\"bd-mwcell\">Soothing humectant and emollient<\/div>\n        <\/div>\n        <div class=\"bd-mwrow bd-hl-warn\">\n          <div class=\"bd-mwcell bd-mwname\">Hyaluronic acid<\/div>\n          <div class=\"bd-mwcell bd-mwval\">20 000 - 2 000 000<\/div>\n          <div class=\"bd-mwcell\">Well over 500: remains on the surface<\/div>\n        <\/div>\n      <\/div>\n      <p class=\"bd-prose\" style=\"margin-top: 22px;\">Glycerin (92) is well below the threshold, moisturizing the deep layers of the epidermis. Hyaluronic acid, on the other hand, weighs between 20,000 and 2 million daltons: it acts above all to <strong>on the surface<\/strong>, by forming a film that retains water without penetrating deeply. That's the difference.<\/p>\n      <div class=\"bd-tip bd-warn\">\n        <span class=\"bd-tip-label\">Good to know<\/span>\n        <p>Very low molecular weight hyaluronic acids (below around 50,000 daltons) are sometimes described in the literature as potentially pro-inflammatory. This point is the subject of scientific debate and suggests that hyaluronic acid should not be seen as a universally superior active ingredient.<\/p>\n      <\/div>\n      <p class=\"bd-prose\">The conclusion is not to avoid hyaluronic acid, but to avoid being influenced by marketing: knowing how to decipher the INCI list allows you to choose products that really correspond to your skin. Glycerine, often at the top of the list, is an excellent first signal.<\/p>\n    <\/div>\n  <\/section>\n\n  <!-- ============ S\u00c9RUMS \u00c0 L'AH ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap\">\n      <div class=\"bd-section-label\">Our selection - BeautyDecoded data<\/div>\n      <h2>Our moisturizing serums <em>with hyaluronic acid<\/em>.<\/h2>\n      <p class=\"bd-prose\">Let's start with a reminder: a good hyaluronic acid serum remains an excellent surface moisturizer, forming a water-retaining film and temporarily smoothing skin texture.

It's simply not superior to the others, and its high molecular weight prevents it from penetrating deep into the skin. A product containing it is not to be avoided, but its presence should not be the only criterion for choice.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>Why is glycerine often preferable?<\/summary>\n          <div class=\"bd-faq-answer\">Its very low molecular weight (92) enables it to penetrate the skin barrier and moisturize the deeper layers of the epidermis, where hyaluronic acid remains mainly on the surface. It is also very well tolerated and inexpensive.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>What is the 500-dalton rule?<\/summary>\n          <div class=\"bd-faq-answer\">It's a benchmark by which a molecule of more than 500 daltons has difficulty penetrating the skin. It's not an absolute rule, as other factors come into play, but it helps to understand why a small humectant like glycerine acts differently from a very high molecular weight hyaluronic acid.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>How do you know if a product is a good moisturizer?<\/summary>\n          <div class=\"bd-faq-answer\">By reading the INCI list: look for humectants (glycerin, urea, panthenol, NMF), emollients (squalane, ceramides) and water-retaining agents. A complete formula combining these three families moisturizes better than a product focused on a single star ingredient.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>What is the BeautyDecoded application?<\/summary>\n          <div class=\"bd-faq-answer\">A mobile application for cosmetic analysis using artificial intelligence. It analyzes INCI lists and generates compatibility scores for 80 skin types. It does not replace a medical consultation, but helps to objectify product selection according to a skin profile.<\/div>\n        <\/details>\n      <\/div>\n    <\/div>\n  <\/section>\n\n  <!-- ============ DISCLAIMER ============ -->\n  <section class=\"bd-disclaimer\">\n    <p>Information for educational purposes only.
