The Ordinary Hyaluronic Acid 2% + B5 is a high-performance, clinical-grade hydration serum designed to provide immediate and lasting moisture to multiple layers of the skin. 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. Available for fast US delivery at theordinaryusa.co.
In the United States, the skin is subject to a staggering variety of environmental pressures that can rapidly siphon moisture from the epidermis. 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.

The science of this serum is centered on the Hyaluronic Acid complex. HA is a glycosaminoglycan that naturally occurs in the skin's extracellular matrix. In clinical dermatology, the molecular weight of HA is critical for performance. High-molecular-weight HA stays on the skin's surface, forming a breathable hydration film that locks in moisture and provides an immediate smoothing effect. Medium-molecular-weight HA penetrates into the middle layers of the stratum corneum to support a moisture reservoir. Low-molecular-weight HA penetrates the deepest to support the skin's natural repair mechanisms and provide long-term plumping. By combining these three weights, the formula provides a 3D hydration network that addresses both surface dryness and internal dehydration. The addition of an HA Crosspolymer ensures a slow-release delivery, maintaining hydration levels consistently for 24 hours.
Pro-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, 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.

To maximize the plumping and hydrating results of this iconic serum, follow these professional application protocols:
- Preparation: Start with a clean face. We recommend the Squalane Cleanser for a lipid-preserving start.
- The Damp Skin Rule: For best results, apply the serum to slightly damp skin. Hyaluronic Acid is a moisture-magnet; applying it to damp skin allows it to pull that surface water into the epidermis, significantly enhancing the plumping effect.
- Application: Dispense 2-3 drops into the palms of your hands and press gently onto the entire face and neck.
- Timing: Use twice daily, in both your morning (AM) and evening (PM) routines.
- Layering: This is a water-based serum and should be applied at the beginning of your routine, after cleansing but before anhydrous (water-free) serums, oils, or heavy creams.
- Seal: Always follow with a moisturizer like Natural Moisturizing Factors + HA to lock in the hydration and prevent transepidermal water loss.
Note: Patch test before first use. Apply only to unbroken skin as directed.
The Ordinary Hyaluronic Acid 2% + B5 is designed for anyone seeking fundamental, non-greasy hydration:
- Dehydrated Skin Profiles: Individuals whose skin feels "tight," "thirsty," or looks dull despite regular moisturizing.
- Anti-Aging Starters: Perfect for US consumers in their 20s and 30s looking to maintain skin volume and prevent early fine lines.
- Oily and Combination Skin: Those who need serious clinical hydration but avoid traditional creams because they feel too heavy or sticky.
- Compromised Barrier Profiles: Anyone whose skin has become sensitized or reactive due to harsh US climates or active treatments.
- Makeup Enthusiasts: Users seeking a smooth, hydrated base that prevents concealer from settling into fine lines.
- All US Skin Profiles: A non-comedogenic, pH-balanced formula that is effective for everything from very oily to very dry skin.
What does The Ordinary Hyaluronic Acid 2% + B5 do?
It provides multi-depth hydration and visible plumping by delivering a 2% concentration of multiple molecular weights of Hyaluronic Acid and 5% Pro-Vitamin B5 to improve the skin's moisture retention and resilience.
Why should I apply it to damp skin?
Hyaluronic Acid works by binding to water molecules. Applying it to damp skin ensures it has a source of moisture to draw into the skin layers, leading to a much more dramatic plumping and hydrating result.
Can I use this with Retinol or Vitamin C?
Absolutely. It is one of the most versatile serums in clinical skincare. Applying Hyaluronic Acid before or after actives can help buffer the skin and reduce the potential for irritation from stronger treatments.
Is this the original or the new formulation?
This is the Original Formulation, celebrated globally for its clinical efficacy. It has a slightly more "tacky" feel upon initial application, which many US users prefer as it indicates the high concentration of the HA crosspolymer.
Will it make my skin look oily?
No. It is an aqueous (water-based) serum that contains zero oils or silicones. It sinks in to leave the skin feeling hydrated and soft rather than shiny or greasy.
Can I use it if I have oily or acne-prone skin?
Yes! Oily skin is often actually dehydrated. This oil-free serum provides the water your skin needs without adding weight or clogging pores.
Does it have a scent?
The product is 100% fragrance-free and virtually odorless, making it ideal for clinical routines and sensitive skin types.
How long will a 30mL bottle typically last?
With twice-daily use (2-3 drops each time), a bottle typically lasts between 2 and 3 months, providing exceptional clinical value.
Is it safe for use during pregnancy?
Yes, Hyaluronic Acid and Pro-Vitamin B5 are naturally occurring substances and are generally considered safe for use during pregnancy. However, we always recommend consulting your US physician with the full ingredient list.
Does it protect against the sun?
No. It provides hydration but contains no SPF. Since maintaining a healthy barrier is key to skin health, always finish your morning routine with a broad-spectrum US sunscreen.
What is an HA Crosspolymer?
It is a next-generation form of Hyaluronic Acid that has been chemically bonded to form a 3D network. This allows for a more sustained release of hydration into the skin over several hours.
Why does the serum feel slightly sticky at first?
The initial "tackiness" is the result of the high concentration of HA molecules and the crosspolymer network. This feeling disappears within seconds as the product absorbs, leaving the skin smooth and primed for moisturizer.
Can I use it around my eyes?
You can apply it to the orbital bone, but avoid direct contact with the eyes. For the eyes, we recommend the specialized Multi-Peptide Eye Serum.
Where should I store it?
Store in a cool, dry place away from direct sunlight. It does not need to be refrigerated, but some US users find that a cold serum feels extra refreshing on the skin in hot climates.
Will it help with my large pores?
By plumping the skin with hydration, it can help the skin surface look firmer, which often makes pores appear less prominent and more refined.
