The Ordinary Hyaluronic Acid 2% + B5 Serum 30ML
The Ordinary Hyaluronic Acid 2% + B5 is a water-based hydrating serum formulated to replenish moisture and improve the appearance of dry, dehydrated and rough-feeling skin. The original formulation combines four types of hyaluronic acid with pro-vitamin B5 (panthenol) to support hydration at different levels of the skin's surface while helping the skin feel smoother and more supple.
Hyaluronic acid is a water-binding ingredient that helps attract and retain moisture, while vitamin B5 supports the skin's moisture barrier and helps improve moisture retention. The combination makes this serum a practical hydration step for skin that feels tight, dry or lacking suppleness.
The original formulation has a richer serum texture compared with The Ordinary's newer Hyaluronic Acid 2% + B5 with Ceramides. It is still water-based, oil-free, alcohol-free and silicone-free, and The Ordinary lists it as suitable for all skin types.

Key Ingredients
Hyaluronic Acid
The formula uses four types of hyaluronic acid, including different molecular weights and a hyaluronic acid crosspolymer. These forms work across different levels of the skin's surface to support hydration and give skin a smoother, more supple appearance.
Pro-Vitamin B5
Also known as panthenol, vitamin B5 supports the formation of skin-barrier components and helps the skin retain moisture.
What Does The Ordinary Hyaluronic Acid 2% + B5 Do?
This is primarily a hydrating serum, rather than a treatment designed around one specific concern such as pigmentation or acne.
It is particularly useful when skin feels:
- Dry
- Dehydrated
- Tight after cleansing
- Rough or lacking softness
- Less plump or supple than usual
By improving hydration, the serum can also make fine dry lines appear less noticeable. However, it should not be considered a standalone treatment for established wrinkles.

Can It Be Used With Other Actives?
Yes. Hyaluronic Acid 2% + B5 is a relatively easy product to incorporate into an active skincare routine.

Its hydrating properties can also help support skin when using potentially drying active ingredients.

It is a hydrating serum designed to replenish moisture, improve skin smoothness and support a more supple, plump-looking complexion.
