What does hyaluronic acid do for the skin?

Hyaluronic acid acts as a humectant, drawing moisture from the air and deeper skin layers to the surface. This helps to keep the skin hydrated, plump, and reduces the appearance of fine lines and wrinkles.

Can hyaluronic acid be used by all skin types?

Yes, hyaluronic acid is generally well-tolerated by all skin types, including sensitive and acne-prone skin, due to its gentle and hydrating nature. It is non-comedogenic and rarely causes irritation.

Should I apply hyaluronic acid to damp or dry skin?

For optimal results, it is often recommended to apply hyaluronic acid to damp skin. This allows the molecule to draw in external moisture, maximizing its hydrating effects on the skin.

Hyaluronic Acid

Hyaluronic Acid is a powerful humectant naturally found in the skin, known for its exceptional ability to attract and hold up to 1,000 times its weight in water. When applied topically, it helps to hydrate the skin's surface, making it appear plumper and smoother. It also supports the skin's barrier function, reducing moisture loss.

Hydration i4 / 4

Whether the ingredient helps increase the skin’s water content — humectants that attract water, ingredients that reduce water loss, or ones that make skin feel less dry.

Whether it can help visible signs of aging — fine lines, wrinkles, loss of firmness, or photoaging.

Barrier support i3 / 4

Whether it supports the skin barrier — restoring lipids, reducing water loss, aiding barrier repair, or strengthening the skin’s protective function.

Texture i2.5 / 4
