FAQ

How is this different from Hyaluronic Acid Serum?

Hyaluronic Acid Serum is a water-based, moisture-binding formula built around sodium hyaluronate for a quick plumping effect. Hydration Serum takes a different, botanical approach centered on Cassia Obtusifolia Seed Extract, designed for daily comfort and balance rather than an immediate surge of hydration.

Should I choose this or Hyaluronic Acid Serum?

If you want a fast, noticeable plump, start with Hyaluronic Acid Serum. If you prefer a calmer, botanical daily formula — or want to layer both — Hydration Serum is built for that.

Can I use both serums together?

Yes. Many people layer Hyaluronic Acid Serum underneath Hydration Serum for both plumping and comfort.

Does it contain hyaluronic acid?

No. This formula is built around Cassia Obtusifolia Seed Extract and glycerin, not sodium hyaluronate.

Is it fragrance-free?

Yes, the formula does not include added fragrance.

Can I use it daily, long-term?

Yes, it's formulated for ongoing daily use.

Where is it made?

Made in North America.
