The Ordinary Hyaluronic Acid 2% + B5 (Reformulated) is a cutting-edge clinical evolution of our most iconic hydration treatment, now enhanced with advanced ceramide technology to provide unparalleled multi-depth moisture and structural barrier support. While the original formula defined the hydration market, this next-generation version addresses the growing demand for a "total hydration" solution that does more than just draw in water. By combining a 2% concentration of low, medium, and high-molecular-weight Hyaluronic Acid (HA) with an HA crosspolymer, this serum creates a 3D hydration network that plumps the skin from within while smoothing the appearance of surface fine lines. The addition of five vital Ceramides and Pro-Vitamin B5 transforms this from a simple humectant serum into a comprehensive barrier-repair powerhouse. The ceramides work to "seal the gaps" in your skin's natural lipid wall, effectively locking in the moisture provided by the HA and preventing transepidermal water loss (TEWL). The result is a measurably softer, more resilient, and deeply hydrated complexion that exhibits a healthy, "bouncy" radiance without the tackiness often associated with older HA formulas. Whether you are battling environmental dehydration or seeking a post-procedure recovery tool, this reformulated solution provides the scientific foundation for healthy, supple skin.

In the United States, the skin is constantly subjected to a wide variety of climatic extremes and environmental aggressors that can rapidly compromise its hydration levels and barrier integrity. For American consumers living in high-altitude or arid desert regions like the Southwest (Arizona, Nevada, New Mexico), the low atmospheric humidity can aggressively siphon moisture from the skin, leading to chronic tightness and flakiness. 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 regardless of the outdoor weather. The Ordinary Hyaluronic Acid 2% + B5 (Reformulated) is a US essential because it provides a "biomimetic" 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 US sunscreens. It meets the high US demand for clinical-grade "Clean Beauty" that prioritizes molecular transparency and clinical performance. Whether you are navigating the smog-heavy commute of Los Angeles or the dry air of a transcontinental flight, this serum provides the resilient hydration infrastructure needed to keep your skin looking polished, plumped, 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. Medium-molecular-weight HA penetrates into the middle layers to support a moisture reservoir. Low-molecular-weight HA penetrates the deepest to support signaling for natural repair. The addition of an HA Crosspolymer ensures a sustained release of hydration over 24 hours, maintaining a "plumped" appearance even in dry US environments.
Ceramides are waxy lipid molecules that constitute approximately 50% of the skin barrier. The science of ceramides involves the "bricks and mortar" model of the skin; while skin cells are the bricks, ceramides are the mortar that holds them together. Our reformulated serum includes five distinct ceramides to provide a comprehensive barrier shield. Ceramide NP provides the primary structural support, while AP, AS, NS, and EOP work synergistically to improve skin moisture retention and protect against the environmental particulate matter common in major US cities. By replenishing these lipids, the serum ensures that the hydration provided by the HA is not lost to the atmosphere.
Pro-Vitamin B5, also known as Panthenol, is a highly effective humectant that excels at attracting and binding atmospheric moisture. Beyond simple hydration, Panthenol is scientifically documented for its ability to support the skin's natural healing processes. It acts as a precursor to pantothenic acid, essential for the synthesis of barrier lipids. At a 5% concentration, it provides a synergistic effect with the HA and Ceramides, creating a "moisture cushion" that helps to soothe redness and promote a more resilient, healthy-looking complexion.

To maximize the plumping and barrier-repair results of this next-generation 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. Applying HA to damp skin allows it to pull 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 actives and provide a final barrier seal.
Note: Patch test before first use. Apply only to unbroken skin as directed.
The Ordinary Hyaluronic Acid 2% + B5 is designed for anyone seeking advanced hydration and barrier support:
- Dehydrated Skin Profiles: Individuals whose skin feels "tight" or "thirsty" regardless of how much moisturizer they use.
- Compromised Barrier Profiles: Anyone whose skin has become sensitized or reactive due to over-exfoliation or harsh US climates.
- 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.
- Post-Procedure Recovery: Individuals seeking a gentle, ceramide-rich way to support skin repair after clinical treatments.
- All US Skin Profiles: A non-comedogenic, pH-balanced formula that is effective for everything from very oily to very dry skin.
What is the difference between the old and new Hyaluronic Acid 2% + B5?
The new reformulated version includes five essential ceramides for added barrier support and features a refined, non-tacky texture for a more elegant skin feel upon application.
Why should I apply it to damp skin?
Hyaluronic Acid works by binding to water. 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 result.
Can I use this with Retinol or Vitamin C?
Absolutely. It is one of the most versatile serums in clinical skincare. Applying it before or after actives can help buffer the skin and reduce the potential for irritation from stronger treatments.
Does it contain real ceramides?
Yes. The reformulated version contains five distinct types of plant-derived ceramides (NP, AP, AS, NS, EOP) to provide comprehensive support for the skin's lipid barrier.
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 dehydrated. This oil-free, non-comedogenic 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 sensitive skin and clinical routines.
How long will a 30mL bottle typically last?
With twice-daily use (2-3 drops), a bottle typically lasts between 2 and 3 months, providing exceptional clinical value.
Is it safe for use during pregnancy?
Yes, Hyaluronic Acid, Ceramides, 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.
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.
Why does the new formula feel less sticky?
We have refined the delivery base to ensure a more "cosmetically elegant" finish. The new texture allows for better layering under makeup and other skincare without pilling.
Can I use it around my eyes?
You can apply it around the orbital bone, but avoid direct contact with the eyes. For specific eye concerns, we recommend The Ordinary Multi-Peptide Eye Serum.
Should I store it in the fridge?
While not required for stability, some US users find that a cold serum feels extra refreshing on the skin in hot climates or for morning depuffing.
Will it help with 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.
Is it suitable for mature skin?
Yes. Mature skin often suffers from lipid depletion. The combination of HA and Ceramides in this formula is ideal for restoring both volume and barrier resilience.
