What is Hyaluronic Acid?

Hyaluronic acid is a sugar molecule naturally found in the skin and the connective tissue in your body. The acid acts as a moisture binder, which means it will attach itself to water in cells, making them plump. 

The main benefits it gives us are keeping the skin moisturized and hydrated. It can also work wonders for those with dry skin. Hyaluronic acid can help combat signs of aging as well.

Hyaluronic acid can draw moisture from the air and keep the skin moist. This is because it holds almost 1000 times its own weight in water. The acid is also not just a moisturizer but it has the ability to hold extra moisture.

Benefits of Hyaluronic Acid

Hyaluronic acid is a great skincare ingredient because it retains moisture. It easily bonds with other water molecules, making it a key factor in retaining the skin’s moisture. 

When you don’t have enough moisture in your skin, this is the best ingredient to use when this happens. Moisture is drawn back into the skin and repairs the skin’s moisture barrier.

The ingredient can be used as a filler. Hyaluronic acid’s composition is closely-related to elements in our bodies. It can also work as a filler, especially one that doesn’t cause major irritation. The acid can add volume to places such as the lips and cheeks, which typically lose volume over time.

It also reduces the appearance of wrinkles. Since dehydrated skin is one of the main causes of wrinkles, hyaluronic acid provides moisture. This can help diminish the appearance of any fine lines and wrinkles.

Another few benefits that come with hyaluronic acid are it absorbs fats and is also non-irritating. Hyaluronic acid quickly sinks into the skin, indicating you lose less of the product. It is safe for use with all skin types as well.

There have also been studies recently showing hyaluronic acid has antioxidant properties. This means it can act as a shield against free radicals that are out of our control. These radicals can be pollution or other environmental aggressors.
