Hyaluronic acid is a naturally occurring substance found in the skin that helps to keep it hydrated and plump. As we age, our skin produces less hyaluronic acid, which can lead to dryness, wrinkles, and fine lines. Hyaluronic acid serums can help to replenish the skin’s natural levels of hyaluronic acid, improving hydration and reducing the appearance of wrinkles.
Hyaluronic acid serums are typically applied to the face after cleansing and toning. They can be used alone or under makeup. Hyaluronic acid serums are generally safe for all skin types, but they may cause irritation in some people. If you have sensitive skin, it is important to do a patch test before using a hyaluronic acid serum.
