Most people know hyaluronic acid primarily as a substance used in creams or in the form of an injection against wrinkles. But hyaluronic acid is also used in many other areas, including for dry or irritated eyes.
Heater air and frost dry out the eyes
Especially in winter, many people suffer from dry, red, or irritated eyes. The reason: In winter, the air becomes drier. Due to frosty temperatures, there is less moisture in the air outside. Indoors, heaters further dry out the room air. Because of the dry air, many people get chapped and cracked lips or dry, sometimes even flaky skin. Hair becomes statically charged more quickly and stands stubbornly on end. And the eyes also dry out. Normally, with every blink, a thin tear film forms over the eye to protect and moisturize it. However, the dry air continuously draws moisture from the eyes. As a result, the protective film is missing. The consequences are dry eyes. Dryness in the eye can lead to a foreign body sensation. You have to blink constantly without the eye becoming better moisturized. It feels scratchy, the eyes burn or become red.
Hyaluronic acid moisturizes and soothes the eyes
Hyaluronic acid is capable of binding very large amounts of water. One gram of hyaluronic acid can absorb up to six liters of water. This makes hyaluronic acid ideal for use on the eye. For excessively dry and burning eyes, eye drops with hyaluronic acid are often used. These ensure that a stable and long-lasting film of moisture forms on the eye. This moistens the dry eye with moisture. At the same time, hyaluronic acid is completely colorless, so vision is not impaired after using products with hyaluronic acid. These properties are not only utilized in medical eye drops and eye care products. Hyaluronic acid is also often found in cleaning and care solutions for contact lenses. It protects the lenses from drying out and keeps them stable in shape. Ophthalmologists use hyaluronic acid not only to moisten the eye but also during procedures and surgeries on the eye.
Hyaluronic acid can also affect the eyes from within
There are a whole range of dietary supplements that contain hyaluronic acid. After ingestion, the hyaluronic acid is supposed to distribute throughout the body and exert its effect from within. It does this in different areas: hyaluronic acid ensures that the skin and mucous membranes in the body can retain water, keeping them firm and elastic. In the cartilage of the joints, hyaluronic acid acts as a "lubricant" and keeps the joints flexible. The mucous membranes of the nose and eyes are kept moist. This is especially important in winter when dry eyes and dry skin occur. But in general, the hyaluronic acid content in the body decreases from the age of 25, and by 40 only half of the original amount remains. As a result, many people tend to have dry skin, dry eyes, and joint problems. The intake of hyaluronic acid can help here. Hyaluronic acid can therefore not only have a soothing and moisturizing effect on dry eyes from the outside, but it can also do so from within.
