Hyaluronic Acid 2% + B5 (Original Formulation)

Product Overview

Meet the "OG" of clinical hydration. The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation) is the serum that redefined affordable skincare. Known for its rich, viscous texture and deep plumping capabilities, this water-based formula is designed to eliminate dehydration and dryness instantly. By combining four distinct types of Hyaluronic Acid with Pro-Vitamin B5, it targets multiple layers of the skin’s surface to ensure long-lasting moisture and a visibly smoother, more supple complexion. If you prefer a hydration hero with a substantial, comforting feel that truly "grips" the skin, the Original Formulation remains the gold standard.

Key Benefits

• Multi-Depth Hydration: Uses low-, medium-, and high-molecular-weight HA to reach different surface depths.
• Instant Plumping: Visibly reduces the look of fine lines caused by dehydration for a "bouncier" skin feel.
• Barrier Strengthening: Supported by Pro-Vitamin B5 to encourage the production of natural skin lipids.
• Smoothing Effect: Refines textural irregularities caused by lack of moisture.
• Rich Texture: A comforting, concentrated serum feel that provides immediate relief to "thirsty" skin.
• Supports Healing: Panthenol (B5) helps calm the skin and supports the repair of the moisture barrier.
• Universal Compatibility: Suited to all skin types, from very dry to oily and acne-prone.
• Cruelty-Free & Vegan: Formulated without animal-derived ingredients or testing.
• The Perfect Base: Preps the skin perfectly for the application of oils, creams, or makeup.
• Clinical Purity: Alcohol-free, oil-free, and silicone-free for a clean hydration boost.

Key Ingredients and The Science Behind Them

• 4 Types of Hyaluronic Acid: This blend includes a next-generation HA crosspolymer and three different molecular weights of HA. While high-weight molecules stay on the surface to prevent water loss, lower weights penetrate deeper to provide internal plumping and structural hydration.
• Pro-Vitamin B5 (Panthenol): Beyond hydration, B5 is a powerhouse for barrier health. It helps the skin produce essential ceramides and fatty acids, ensuring your skin doesn't just feel hydrated, but *stays* hydrated by keeping the "exit doors" for moisture closed.

How to Use

1. Prep: Apply a few drops to the face in the morning (AM) and evening (PM).
2. Pro-Tip: For best results, apply to damp skin. This gives the Hyaluronic Acid molecules extra water to "grab" and pull into the skin.
3. Sequence: Apply after cleansing and before heavier serums, oils, or moisturizers.
4. Layering: If using multiple water-based serums, apply Hyaluronic Acid first to provide a hydration foundation.

Who is it for?

• Classic Fans: Long-time users who love the original, rich feel of The Ordinary’s first HA serum.
• Very Dehydrated Skin: Those who need a more substantial moisture "cushion."
• Active Ingredient Users: Anyone using Retinoids or Acids who needs to keep their barrier hydrated.
• All Ages: From teenagers starting a routine to mature skin needing a plumping boost.

FAQ

Q: What is the difference between this and the "with Ceramides" version?
A: The Original Formulation has a thicker, richer texture. The newer version (with Ceramides) is much thinner and more lightweight. If you have very dry skin, you will likely prefer this original version.

Q: Why does it feel slightly tacky?
A: Because of the high 2% concentration of HA, a temporary tackiness is normal. Simply wait 30 seconds for it to absorb, or apply to damp skin to reduce this effect.

Q: Can I use this with Vitamin C?
A: Yes! It is an excellent pairing. Apply Hyaluronic Acid first to hydrate, followed by your Vitamin C treatment.

Q: Can I use it on oily skin?
A: Absolutely. It is oil-free and non-comedogenic, providing the hydration oily skin needs without adding grease.
