What is hyaluronic acid?
Hyaluronic acid is a humectant – a substance that retains moisture – and is able to bind to more than a thousand times its weight in water. This substance is found naturally in many areas of the human body, including the skin, eyes, and synovial fluid of joints. The hydrochloric acid used in beauty and skin care products is primarily made by bacteria in a laboratory via a process called biofermentation.

As we age, the production of essential substances in the skin, including hyaluronic acid (along with collagen and elastin), decreases. As a result, our skin loses volume, hydration and plumpness.

Benefits of hyaluronic acid for the skin

Hyaluronic acid penetrates the top layer of the skin and supplies it with the moisture it needs. Hence, this acid is an effective facial moisturizer, as it makes the skin less susceptible to damage from external and environmental factors.

Hyaluronic acid acts as an antioxidant, as it is able to trap free radicals that are primarily responsible for skin aging. This helps fight wrinkles and fine lines.

Hyaluronic acid repairs cells and tissues damaged by aging.

Hyaluronic acid contributes to the maintenance and strengthening of collagen in connective tissues. The latter is one of the four major tissue types in the body that support, connect, or separate different types of tissues and organs.

Hyaluronic acid contributes to tightening the skin and preventing it from sagging over time.

Hyaluronic acid helps smooth the skin thanks to the hydration that penetrates into the layers of the skin.
