Hyaluronic Acid (HA) is a naturally occurring molecule in the human body capable of holding up to 1,000 times its weight in water; however, the molecular size of HA often determines how effectively it can penetrate the skin's surface. This iconic original formulation utilizes a sophisticated complex of three distinct molecular weights of Hyaluronic Acid—low, medium, and high—alongside a next-generation HA crosspolymer. This multi-depth approach ensures that hydration is not merely sitting on the surface but is delivered into the deeper epidermis to plump the skin and smooth the look of fine lines. Fortified with 5% Pro-Vitamin B5, the formula further enhances surface hydration while providing a soothing effect on the skin barrier. The result is a measurably softer, smoother, and more resilient complexion that exhibits a healthy, \"bouncy\" radiance. Whether you are dealing with seasonal dryness or chronic dehydration, this water-based serum serves as the fundamental cornerstone of any effective clinical skincare ritual.

For American consumers living in major metropolitan hubs like New York City, Chicago, or Los Angeles, the constant exposure to urban pollution and the daily grind can lead to \"City Skin\"—characterized by chronic dehydration and a lackluster appearance. Conversely, in the arid climates of the Southwest or the moisture-stripping winters of the Northeast, the prevalence of indoor heating and air conditioning creates a \"recycled\" dry air environment that compromises the skin's barrier integrity regardless of the outdoor weather. The Ordinary Hyaluronic Acid 2% + B5 is essential for the US market because it provides a \"bio-identical\" solution to these challenges. Its non-comedogenic, oil-free nature is perfectly suited for the fast-paced American lifestyle, absorbing rapidly and sitting comfortably under makeup or high-SPF sunscreen. It meets the sophisticated demand in the USA for high-potency \"Clean Beauty\" that prioritizes molecular transparency and clinical performance. Whether you are navigating a smog-heavy commute or the dry air of a transcontinental flight, this serum provides the resilient hydration infrastructure needed to keep your skin looking polished and protected in any regional environment.\u003c\/p\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eKey Benefits of The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntensive Multi-Depth Hydration:\u003c\/strong\u003e Utilizes low, medium, and high molecular weight HA to deliver moisture to various levels of the skin surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmediate Plumping Effect:\u003c\/strong\u003e Rapidly draws moisture into the skin, making the complexion look fuller, more youthful, and revitalized.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisible Smoothing of Fine Lines:\u003c\/strong\u003e By rehydrating the skin's structural layers, it effectively softens the appearance of dehydration-induced wrinkles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Barrier Support:\u003c\/strong\u003e Fortified with 5% Pro-Vitamin B5 to soothe the skin and reinforce the natural moisture-retaining barrier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Comedogenic \u0026amp; Oil-Free:\u003c\/strong\u003e A lightweight, aqueous formula that provides deep hydration without clogging pores or feeling greasy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Post-Treatment Calm:\u003c\/strong\u003e Ideal for soothing the skin after using high-strength clinical actives like Retinoids or Direct Acids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimizes Skincare Routine:\u003c\/strong\u003e Preps the skin for better absorption of subsequent treatments, acting as a high-performance hydration \"primer.\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced HA Crosspolymer:\u003c\/strong\u003e Features a next-generation delivery system for sustained hydration throughout the day and night.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproves Skin Suppleness:\u003c\/strong\u003e Noticeably improves skin elasticity and \"bounce-back\" from the very first application for a polished US look.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Versatility:\u003c\/strong\u003e A fundamental hydration layer that is effective and safe for all US skin profiles, including the most sensitive.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid Absorption Formula:\u003c\/strong\u003e Sinks in instantly with zero sticky residue, perfect for effortless layering in a busy routine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSustainably \u0026amp; Ethically Produced:\u003c\/strong\u003e A 100% vegan and cruelty-free formula that meets the highest US clinical standards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eKey Ingredients and The Science Behind Them\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003e2% Hyaluronic Acid Complex (Low, Medium, and High Molecular Weight)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eThe science of this serum is centered on the \u003cstrong\u003eHyaluronic Acid\u003c\/strong\u003e complex.

Beyond simple hydration, Panthenol is scientifically documented for its ability to support the skin's natural repair processes. It acts as a precursor to pantothenic acid, which is essential for the synthesis of barrier lipids like ceramides and cholesterol. At a 5% concentration, it provides a synergistic effect with the Hyaluronic Acid, creating a \"moisture cushion\" on the skin surface that helps to soothe redness and promote a more resilient, healthy-looking complexion. It is particularly effective for American consumers whose skin has been sensitized by environmental particulate matter or over-exfoliation.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eSpecifications Table\u003c\/strong\u003e\u003c\/div\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Name\u003c\/td\u003e\n\u003ctd\u003eHyaluronic Acid 2% + B5 (Original)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eThe Ordinary\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFormat\u003c\/td\u003e\n\u003ctd\u003eWater-Based Aqueous Serum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKey Actives\u003c\/td\u003e\n\u003ctd\u003e30% HA Complex, 5% Pro-Vitamin B5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Level\u003c\/td\u003e\n\u003ctd\u003eApproximately 6.50 – 7.50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTargets\u003c\/td\u003e\n\u003ctd\u003eDehydration, Plumping, Fine Lines, Barrier Support\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuited To\u003c\/td\u003e\n\u003ctd\u003eAll Skin Types (Ideal for Dehydrated or Oily Skin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolume\u003c\/td\u003e\n\u003ctd\u003e30mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVegan \/ Cruelty-Free\u003c\/td\u003e\n\u003ctd\u003eYes \/ Yes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUS Availability\u003c\/td\u003e\n\u003ctd\u003eOfficial US Store — theordinaryusa.co\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eHow to Use The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eTo maximize the plumping and hydrating results of this iconic serum, follow these professional application protocols:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreparation:\u003c\/strong\u003e Start with a clean face.

Unlike traditional hydrating serums that rely solely on surface humectants, this advanced formula utilizes a potent 17% (by weight) solution of amino acids and amino acid derivatives. Amino acids are the vital building blocks of the skin's own Natural Moisturizing Factors (NMF), which are responsible for maintaining the stratum corneum’s hydration, plasticity, and enzymatic activity. By mimicking the skin's biological composition, this aqueous serum works in perfect harmony with your skin's natural processes to reinforce barrier resilience and provide immediate, weightless softening. The formula is further fortified with a 5% concentration of Pro-Vitamin B5 (Panthenol), which offers both surface-level and deeper hydrating properties while simultaneously acting as a soothing agent to mitigate visible irritation. The result is a measurably smoother, more supple, and better-protected complexion that feels completely natural and non-greasy. Its \"ultra-thin\" consistency ensures rapid absorption, making it an ideal \"hydration booster\" that can be integrated into any existing clinical routine without pilling or weight.

For American consumers living in high-altitude or arid desert regions like the Southwest (Arizona, Nevada, Utah), the low atmospheric humidity can rapidly siphon moisture from the skin, leading to chronic dehydration and a \"tight\" feeling. Conversely, in major US metropolitan hubs such as New York City, Chicago, or Atlanta, the prevalence of indoor climate control—heating in the winter and air conditioning in the summer—creates a localized environment of \"recycled\" dry air that compromises the skin's barrier integrity regardless of the outdoor weather. The Ordinary Amino Acids + B5 is a US essential because it provides a \"bio-identical\" solution to these challenges. Its ultra-lightweight, non-comedogenic nature is perfect for the fast-paced American lifestyle, absorbing in seconds and sitting comfortably under makeup or high-SPF sunscreen. Whether you are battling the freezing winds of a Northeast winter or the intense heat of a Southern summer, this serum acts as a critical hydration foundation, ensuring your skin remains resilient, hydrated, and polished in any zip code. It directly addresses the US demand for minimalist yet clinically potent skincare that supports the skin's biological health without unnecessary additives.\u003c\/p\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eKey Benefits of The Ordinary Amino Acids + B5\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBio-Identical Hydration:\u003c\/strong\u003e Utilizes a 17% concentration of amino acids that reflect the natural composition of the skin’s own moisture-retaining system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Depth Moisture Support:\u003c\/strong\u003e 5% Pro-Vitamin B5 provides immediate surface hydration while supporting moisture retention in the deeper outer layers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Barrier Reinforcement:\u003c\/strong\u003e Strengthens the skin’s natural defenses against environmental dehydration, pollutants, and urban irritants.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-Lightweight \"Thin\" Texture:\u003c\/strong\u003e An aqueous formula that absorbs instantly with zero residue, ideal for layering or for those who dislike heavy serums.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmediate Skin Softening:\u003c\/strong\u003e Noticeably improves skin suppleness and texture from the very first application for a polished look.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Comedogenic \u0026amp; Oil-Free:\u003c\/strong\u003e Water-based and free from oils and silicones, making it safe for acne-prone, oily, and combination skin types.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalms Visible Irritation:\u003c\/strong\u003e Pro-Vitamin B5 acts as a soothing agent to reduce the appearance of redness and surface sensitivity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimizes Routine Performance:\u003c\/strong\u003e Preps the skin surface for better absorption of subsequent treatments, acting as a high-performance \"primer.\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Concentration Efficacy:\u003c\/strong\u003e Delivers professional-grade levels of active ingredients for visible, science-backed results.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduces Transepidermal Water Loss:\u003c\/strong\u003e Helps the skin lock in moisture more effectively by sealing the gaps in the lipid barrier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Versatility:\u003c\/strong\u003e A fundamental hydration layer that is effective for all US skin profiles, including the most sensitive.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSustainably \u0026amp; Ethically Formulated:\u003c\/strong\u003e A 100% vegan and cruelty-free formula that meets the highest US clinical standards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eKey Ingredients and The Science Behind Them\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003e17% Amino Acid Solution (and Derivatives)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eThe core science of this serum revolves around the high-potency concentration of amino acids, which constitute approximately 40% of the skin’s Natural Moisturizing Factors (NMF). These molecules, including Arginine, Aspartic Acid, Glycine, and Alanine, are responsible for maintaining the osmotic balance within the skin cells and ensuring the stratum corneum remains flexible. In clinical dermatology, amino acids are recognized not only as humectants that draw water into the skin but also as critical regulators of pH and skin barrier maintenance. Our 17% concentration is significantly higher than that found in standard moisturizers, providing an intensive boost of these biological building blocks. By reinforcing the skin's NMF, the serum ensures that the skin doesn't just \"feel\" hydrated, but is functionally better at retaining its own moisture against external stressors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003e5% Pro-Vitamin B5 (Panthenol)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003ePro-Vitamin B5, also known as Panthenol, is a highly effective humectant that excels at attracting and binding atmospheric moisture to the skin. Beyond simple hydration, Panthenol is scientifically documented for its ability to support the skin's natural repair processes. It acts as a precursor to pantothenic acid, a component of Coenzyme A, which is essential for cellular energy and the synthesis of barrier lipids. At a 5% concentration, it provides a synergistic effect with the amino acids, creating a \"moisture cushion\" on the skin surface that helps to soothe redness and promote a more resilient, healthy-looking complexion.
