In our eternal quest for eternally youthful skin—even skin tone, plumpness, and radiance—we’re also eager to try promising new products that sweep through the beauty scene.
Whether you’re obsessed with breakthroughs in skincare—or have a standard, tried-and-true wash-and-moisturize routine—you’ve probably heard of hyaluronic acid and its potential to remedy the signs of sun damage and age.
But what is hyaluronic acid, exactly?
Also known as hyaluronan, hyaluronate, or simply “HA,” hyaluronic acid occurs naturally in the body and is essential for maintaining joints and connective tissues. Found in our skin (where a whopping 50 percent of our body’s supply of it is contained), hyaluronic acid acts as a space-filler between cells—almost like a pillow of moisture that functions as a cushion.
It also plays a vital role in retaining moisture, with the experts over at Allure explaining that a single molecule of hyaluronic acid can hold up to 1,000 times its own weight in water.
