The Hyaluronic Acid 3 Serum COSRX

An intensely hydrating serum with no less than 3% hyaluronic acid, an above-average percentage in skincare. Hyaluronic acid is known as one of the most effective hydrating ingredients because it helps attract and retain moisture in the skin. The result is skin that looks plumper, suppler, and fresher.

Suitable for use from the early 20s, as hydration is the basis of healthy skin. Due to factors such as air conditioning, heating, sun, stress, and intensive skincare routines, almost every skin needs extra hydration. The mild formula can also be carefully applied around the eyes.

The formula combines hyaluronic acid with ceramides and NMF (Natural Moisturizing Factors) to not only replenish hydration but also support the skin barrier. Perfect for dry, dehydrated, tight, or sensitive skin that needs extra comfort and long-lasting hydration. The light serum texture absorbs quickly without a sticky feeling and works well with other skincare ingredients such as vitamin C, retinal, niacinamide, and peptides. This allows the serum to easily fit into almost any skincare routine.

Use the serum both morning and evening for skin that feels smoother, plumper, and visibly more hydrated.

The difference from the Torriden Dive In Serum (also a hydrating serum) lies mainly in the texture and focus. Torriden feels light, watery, and extra soothing on the skin, while COSRX focuses more on intensive hydration, comfort, and supporting the skin barrier. As a result, the texture of COSRX also feels slightly richer. Both serums give the skin a strong hydration boost. Which one is best for you mainly depends on the texture you prefer and how much nourishment your skin needs.
