What is hyaluronic acid really? We break down the science behind this superstar hydrator and explain how it works in skincare to plump and rejuvenate the skin

More Than a Buzzword: A Molecular Powerhouse
Hyaluronic Acid (HA) is often hailed as a hydration hero, but its function is rooted in remarkable biology. Naturally present in our skin, it’s a sugar molecule with an almost magical capacity to hold up to 1000 times its weight in water.
How It Works: A Dual-Action Mechanism
- Surface Hydration: Higher molecular weight HA forms a breathable, hydrating film on the skin’s surface, providing immediate smoothing and a dewy plumpness.
- Deep-Skin Support: Lower molecular weight HA can penetrate deeper, helping to bind water within the skin’s structure and support the extracellular matrix that keeps skin firm.
Why Our Skin Craves It
Unfortunately, natural HA levels deplete with age, sun exposure, and environmental aggressors. This leads to a loss of volume, increased appearance of fine lines, and that general feeling of tightness. Replenishing HA topically is a direct way to combat these signs.
HA in TOFANN Formulas: Intentional Integration
We don’t just add HA for the label. In products like our Gentle Hydration Toner, it delivers an instant surge of moisture to prep the skin. In our Daily Resilience Lotion, it works alongside squalane to create a long-lasting hydration reservoir that shields skin from daily stressors. It’s about choosing the right type and pairing it with complementary ingredients for tangible results.
The Bottom Line
HA is a non-negotiable for modern hydration. It’s a potent, skin-compatible ingredient that effectively addresses moisture loss from the inside out and the outside in.
