🧬 What is Hyaluronic Acid?

Hyaluronic Acid (HA) is a naturally occurring molecule found in the skin, connective tissue, and eyes. It acts like a moisture magnet, capable of holding up to 1,000 times its weight in water.

⚙️ How It Works on the Skin

💧 Multi-Depth Hydration

The Ordinary’s formula includes low, medium, and high molecular weight HA, which penetrate different layers of the skin:

High molecular HA: Surface hydration (plumping)
Medium molecular HA: Mid-layer hydration
Low molecular HA: Deep hydration for lasting effects

“Using multiple molecular weights ensures broader hydration — both surface and beneath the skin,” explains DECIEM.

🧪 Role of Vitamin B5 (Panthenol)

Vitamin B5 enhances the surface hydration and supports the skin’s barrier function, allowing for better water retention.
