The COSRX The Hyaluronic Acid 3 Serum is a lightweight, hydrating serum that is formulated with three types of hyaluronic acid, which are known for their ability to attract and retain moisture. Hyaluronic acid is a naturally occurring substance in the skin that helps to keep it hydrated, plump, and youthful-looking. However, as we age, our skin's natural hyaluronic acid levels decrease, which can lead to dryness, fine lines, and other signs of aging.

The three different types of hyaluronic acid in this serum work together to provide different levels of hydration to different layers of the skin. This means that the serum can help to hydrate the deeper layers of the skin, as well as the surface, leaving it looking and feeling more supple.

This serum is suitable for all skin types, including oily and acne-prone skin. To use the serum, simply apply a small amount to the face and neck after cleansing and toning, and follow with your usual moisturizer. You can use it in the morning and/or evening, depending on your preference.
