Hyaluronic acid is a key molecule in the extracellular matrix, vital for maintaining tissue hydration and lubrication, particularly in skin and joints. With age, endogenous levels decline, contributing to wrinkles and joint stiffness. Oral supplementation aims to counteract this decline, with evidence suggesting it is absorbed and distributed to tissues, potentially improving skin moisture and alleviating joint discomfort.
Verdict
A safe supplement for targeted joint and skin support, not systemic aging.
