Hyaluronic Acid Body (Navigating the world of aesthetics)

1. What is Hyaluronic Acid?

• Molecule naturally present in the skin, joints, eyes.
• Exceptional capacity to retain water → key role in hydration, tone and skin elasticity.
• With age: progressive reduction → wrinkles, sagging, loss of volume.
• In aesthetic medicine: used as a resorbable filler to restore, correct or beautify.
