What Is Hyaluronic Acid?

Hyaluronic acid (HA) is a naturally occurring substance found throughout the human body, with the highest concentrations in the skin, joints, and eyes. It is a glycosaminoglycan — a type of molecule that attracts and retains water — and plays a critical role in keeping tissues lubricated, cushioned, and hydrated.

Despite the word "acid" in its name, hyaluronic acid is gentle and well-tolerated, making it one of the most popular ingredients in both skincare and wellness supplements.

How Does Hyaluronic Acid Work?

Hyaluronic acid is remarkable for its ability to hold up to 1,000 times its own weight in water. This makes it a powerful humectant — it draws moisture into tissues and holds it there. In the skin, this translates to improved hydration, plumpness, and elasticity. In the joints, it acts as a lubricating cushion between cartilage surfaces.

Natural Decline with Age

The body produces hyaluronic acid naturally, but production declines significantly with age. By the time we reach our 40s and 50s, HA levels can drop considerably, contributing to drier skin, reduced joint comfort, and loss of skin volume. Supplementing with hyaluronic acid is one way to help support the body's natural reserves.

Hyaluronic Acid and Collagen

Hyaluronic acid and collagen work synergistically. While collagen provides the structural framework of the skin and connective tissue, hyaluronic acid keeps that structure hydrated and supple. Many premium supplements combine both for this reason. Read more: What Is Fish Collagen?

How to Take Hyaluronic Acid

Hyaluronic acid is available in capsule or powder form. It is best taken consistently as part of a daily routine. When combined with vitamin C (which supports collagen synthesis), the benefits may be further enhanced.
