Why Size Matters When It Comes to Hydration
When it comes to hydration, not all hyaluronic acid is created equal. At Elysian, we focus on ultra-low molecular weight hyaluronic acid—a refined form designed to support deeper, more effective hydration where delicate tissue needs it most.

What Is Hyaluronic Acid?
Hyaluronic acid (HA) is a naturally occurring molecule found throughout the body, particularly in the skin and connective tissues. Its primary role is to bind and retain moisture, helping tissues stay supple, resilient, and comfortable.
Because it holds up to 1,000 times its weight in water, hyaluronic acid has long been used in skincare to promote hydration and softness.
Why Molecular Weight Matters
Not all hyaluronic acid behaves the same way. Its effectiveness depends greatly on molecular size.
High molecular weight HA tends to sit on the surface of the skin, helping create a temporary smoothing effect.
Ultra-low molecular weight HA, on the other hand, is smaller in size, allowing it to absorb more easily and support hydration beneath the surface.
This distinction is especially important when caring for delicate intimate skin, which benefits from hydration that reaches beyond the surface layer.
The Advantage of Ultra-Low Molecular Weight HA
At Elysian, we intentionally use ultra-low molecular weight hyaluronic acid because it is designed to:
Support deeper, longer-lasting hydration
Help maintain softness and elasticity
Provide comfort without heaviness or residue
Complement the skin’s natural moisture balance
This makes it particularly well-suited for sensitive areas where comfort and balance matter most.
Thoughtfully Paired With Botanical Support
Our formulas combine ultra-low molecular weight hyaluronic acid with carefully selected botanicals—such as calendula, chamomile, and nourishing plant oils—to create a gentle yet effective experience.
Together, these ingredients work in harmony to:
Soothe delicate skin
Support natural moisture balance
Promote a feeling of lasting comfort
Designed for Intimate Wellness
Intimate skin requires more than surface-level care. That’s why our formulations are designed with intention—prioritizing gentleness, compatibility, and comfort over harsh or overly aggressive ingredients.
Each formula is:
Hormone-free
Thoughtfully balanced
Designed for daily or regular use
Why It Matters
Comfort isn’t a luxury—it’s essential.By choosing formulations that respect the body’s natural systems, you support long-term wellness rather than short-term fixes.
Ultra-low molecular weight hyaluronic acid helps deliver hydration where it matters most—so you can feel confident, comfortable, and cared for.
