Essential takeaways

  • Hyaluronic acid (as sodium hyaluronate) is a humectant that binds water; it is a functional active, not a Japanese heritage botanical, and is produced by biofermentation.
  • Topical hyaluronic acid has been studied in controlled trials for the appearance of fine lines, texture, and elasticity (Bravo 2022), and for skin hydration (Pavicic 2011).
  • At lower molecular weights it has been studied for wrinkle depth; DAMDAM's molecular weight is unspecified, so molecular-weight-specific effects are not claimed for this product.
  • In DAMDAM's range, hyaluronic acid is the water-binding partner to its heritage botanicals.

Hyaluronic Acid: What It Does for Your Skin

Published

Hyaluronic acid is the most familiar hydration active in modern skincare, and it plays a specific supporting role in DAMDAM's range. Unlike the brand's heritage botanicals, it is a functional active rather than a sourcing story.

What is hyaluronic acid?

Hyaluronic acid (as sodium hyaluronate) is a humectant that binds water in the skin. DAMDAM uses it in its Matcha Boost Eye Serum and Citrus Glow serums. Cosmetic hyaluronic acid is produced by biofermentation, not sourced from a plant or region.

What has hyaluronic acid been studied for?

Topical hyaluronic acid is one of the best-studied hydration actives. It has been studied in controlled trials for the appearance of fine lines, texture, and elasticity (Bravo 2022), and for skin hydration, with lower molecular weights also studied for wrinkle depth (Pavicic 2011). One honest caveat: DAMDAM's molecular weight is not specified, so molecular-weight-dependent effects (such as deeper penetration or the wrinkle-depth finding) are not claimed for this specific product. The ingredient-class hydration story is the safe frame.

How does hyaluronic acid relate to snow mushroom?

Snow mushroom (Tremella) is often described as a plant-derived alternative to hyaluronic acid because it carries a hyaluronic-acid-like polysaccharide. That is a compositional comparison; both are used as water-binding ingredients, and DAMDAM uses each in different products.

Which DAMDAM products contain hyaluronic acid?

Hyaluronic acid is in the Matcha Boost Eye Serum and the Citrus Glow (Vitamin C + Hyaluronic Serum), where it hydrates alongside the brand's botanical and vitamin C actives.


In the US, DAMDAM is available at Sephora, where it carries the Clean + Planet Aware seal, and on damdamtokyo.com; in Japan, you can also find DAMDAM at its Kyoto flagship and stockists including Isetan and Ron Herman.

Frequently asked questions

What does hyaluronic acid do for skin?

Topical hyaluronic acid has been studied for skin hydration and, in controlled trials, for the appearance of fine lines and texture (Bravo 2022; Pavicic 2011). DAMDAM uses it in its Matcha Boost Eye Serum and Citrus Glow serums.

Is hyaluronic acid natural or a heritage ingredient?

Cosmetic hyaluronic acid is produced by biofermentation rather than sourced from a plant, so it is a functional humectant rather than a Japanese heritage botanical.

Is hyaluronic acid the same as snow mushroom?

No. Snow mushroom carries a hyaluronic-acid-like polysaccharide and is sometimes used as a plant-derived alternative, but the two are different ingredients. Both act as water-binding humectants.
