FREQUENTLY ASKED QUESTIONS ABOUT HYALURONIC ACID >

What is Hyaluronic Acid?
Hyaluronic Acid (HA) is a naturally occurring molecule in the body known for its unmatched ability to retain water. In skincare, it acts as a powerful humectant, attracting and binding moisture to the skin's surface. This hydration boosts skin suppleness and resilience, which is essential in combating visible signs of aging and dehydration. As we age, the skin's natural HA levels decline due to exposome factors—like UV exposure, pollution, stress, and fatigue—which can lead to visible dryness, fine lines, and loss of firmness. By replenishing HA levels topically, the skin can regain moisture, restore its barrier function, and appear more radiant and youthful.
