Frequently Asked Questions

What does "ultra-low molecular weight" mean in the ISNTREE Ultra Low Molecular Hyaluronic Acid Mask?

Hyaluronic Acid exists in different sizes. High-molecular HA (over 500 kDa) sits on the skin surface and provides excellent surface hydration and a plumping feel. Ultra-low molecular HA (500 Da — daltons, not kilodaltons) is small enough to penetrate through the skin's outer barrier and deliver moisture at deeper epidermal layers. ISNTREE formulates with 8 HA types all at 500 Da — meaning the hydration delivered by this mask goes further and lasts longer than a standard HA mask.

What is Ulleungdo Deep Sea Water and why does the ISNTREE HA Mask use it?

Ulleungdo is a remote volcanic island off the northeast coast of South Korea. Its deep sea water is naturally rich in calcium, magnesium, and potassium — minerals that are absorbed into the skin and help prevent trans-epidermal moisture loss. At 100,000 PPM (10% concentration), the mineral-dense deep sea water in the ISNTREE formula supports the HA complex's hydration by helping the skin retain the moisture delivered.

Is the ISNTREE Ultra Low Molecular Hyaluronic Acid Mask suitable for oily or acne-prone skin?

Yes. The formula is free from harsh alcohols, silicones, parabens, and sulfates. Squalane is used as the emollient of choice — a non-comedogenic, skin-identical lipid that provides a moisture seal without contributing to pore congestion. The mask is suitable for all skin types including oily and acne-prone.

Does the ISNTREE Ultra Low Molecular Hyaluronic Acid Mask contain fragrance?

Yes. The formula includes Lavandula Angustifolia (Lavender) Flower Extract and Salvia Sclarea (Clary) Extract, which contribute a natural botanical scent. There are no synthetic fragrances or parfum listed. Customers with fragrance sensitivity should patch test.
