At 95%, the Mary\u0026amp;May Marine Collagen Serum uses low-molecular-weight marine-derived Hydrolysed Collagen as the overwhelming primary ingredient, building a formula whose amino acid content and penetration efficiency are both genuinely high rather than choosing one over the other. Marine collagen derived from fish has a structural compatibility with human skin collagen that makes it more bioavailable than bovine or porcine alternatives, and at 95% concentration, each application delivers a meaningful amino acid dose to the layers of skin where collagen support actually produces visible changes in firmness and plumpness. Mary\u0026amp;May is a Seoul-based South Korean brand built on high-concentration actives and full EWG ingredient transparency.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\n\u003cp\u003eThe formula delivers high-penetration marine collagen support, visible plumping, improved skin elasticity, and barrier hydration through a 95% low-molecular-weight Hydrolysed Collagen base.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e95% Low-Molecular-Weight Marine Collagen for Structural Support:\u003c\/strong\u003e Low-molecular-weight Hydrolysed Collagen delivers amino acids (glycine, proline, hydroxyproline) to the upper dermis that signal fibroblast activity and support the skin's own collagen synthesis pathway. The penetration advantage of low versus high molecular weight collagen means the amino acid delivery is substantive rather than surface-level, and the marine source ensures higher biocompatibility with human skin collagen than terrestrial alternatives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisible Plumping and Hydration:\u003c\/strong\u003e Marine collagen's strong water-binding capacity delivers immediate surface plumping and a visibly more supple, bouncy skin feel that is noticeable from the first use alongside the gradual structural improvements that develop over weeks of consistent application.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSkin Elasticity and Resilience Over Time:\u003c\/strong\u003e Consistent daily amino acid delivery from low-molecular collagen has been shown in peer-reviewed research to improve skin elasticity and reduce the rate of visible skin ageing, with measurable results at four to six weeks of consistent use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHyaluronic Acid for Supporting Hydration:\u003c\/strong\u003e Sodium Hyaluronate provides complementary surface hydration that maintains comfortable skin moisture and amplifies the plumping effect of the collagen amino acids through simultaneous multi-mechanism hydration activity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThis serum contains Hydrolysed Collagen derived from fish.

At 95%, the collagen content is the formula — producing amino acid delivery at a dose genuinely capable of supporting fibroblast signalling rather than providing a label claim.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Molecular Weight for Penetration Where High-Concentration Products Cannot Reach:\u003c\/strong\u003e Many high-collagen-percentage products use large-molecule collagen that sits on the surface as a film-forming agent. The low-molecular-weight specification in this formula is the formulation decision that makes the concentration meaningful rather than superficial.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEWG Green-Grade Verified:\u003c\/strong\u003e Free from parabens, artificial fragrance, alcohol, and mineral oil.

Low-molecular-weight collagen passes through the skin barrier to reach the upper dermis, where it delivers amino acids that support fibroblast activity and the skin's own structural protein synthesis. The penetration difference means a lower concentration of low-molecular collagen produces more substantive structural benefit than a higher concentration of large-molecule collagen at equivalent application frequency.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this alongside a peptide serum?\u003c\/strong\u003e\u003cbr\u003eA: Yes, and the combination is complementary. Collagen provides amino acid building blocks and direct water-binding capacity; peptides signal cells to produce their own structural proteins. Used together they address skin longevity from structural supply and cellular signalling angles simultaneously. Apply the lighter-textured product first.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How long before I see results?\u003c\/strong\u003e\u003cbr\u003eA: Improved hydration and a subtle plumping effect are typically noticeable within the first week. Meaningful changes to firmness and elasticity generally require four to six weeks of consistent daily use, reflecting the skin's natural cell renewal and collagen remodelling timeline.\u003c\/p\u003e\n\n\u003cp\u003eThe Mary\u0026amp;May Marine Collagen Serum is the collagen serum for those who understand that 95% of a molecule that reaches the dermis is more useful than 95% of one that does not.\u003c\/p\u003e\n\n\u003cdiv class=\"sn-explore-more\"\u003e\n\u003cp\u003eFor a full structural support routine, pair this serum with the \u003ca class=\"sn-ilink\" href=\"\/collections\/collagen\"\u003ecollagen collection\u003c\/a\u003e — creams, masks, and targeted treatments for firmer skin.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca class=\"sn-ilink\" href=\"\/collections\/collagen\"\u003eCollagen\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca class=\"sn-ilink\" href=\"\/collections\/wrinkles-aging\"\u003eWrinkles \u0026amp; ageing\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca class=\"sn-ilink\" href=\"\/collections\/mary-may\"\u003eMore from Mary\u0026amp;May\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Mary\u0026May","offers":[{"title":"Default Title","offer_id":52921681641806,"sku":"MMS01-SM","price":17.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0798\/5057\/0062\/files\/MMS01-SM.png?v=1778671450","url":"https:\/\/skin-nomad.fr\/products\/mary-may-marine-collagen-serum","provider":"Skin-Nomad","version":"1.0","type":"link"}
