hyaluronic acid
Hyaluronic acid (HA) is a glycosaminoglycan naturally present in skin, joints, and connective tissues that plays a crucial role in tissue hydration and cellular processes. It works by binding up to 1000 times its weight in water, providing moisture retention, supporting skin barrier function, and stimulating collagen production. Primarily used in dermatology and cosmetics for skin rejuvenation, anti-aging effects, and improving skin hydration, elasticity, and wound healing.
Lab Notes — Research Studies
01 Oral sodium hyaluronate improves skin hydration, barrier function and signs of aging: a randomized, double-blind, placebo-controlled trial in 150 healthy adults
A 12-week trial found that oral sodium hyaluronate at 120 mg/day significantly enhanced skin hydration and elasticity while reducing transepidermal water loss, sebum, and wrinkle depth compared to placebo, with improvements in epidermal thickness and dermal density.
