Verdict

The gold-standard cosmetic humectant. Endogenous molecule identical to human skin HA. Binds up to 1000× its weight in water. Backed by decades of clinical evidence for moisturization, anti-aging, barrier repair, and wound healing. No EU or US restrictions. Suitable for all skin types including sensitive and reactive. Highest-frequency cosmetic HA ingredient globally.

US Note
