Every season, the skincare industry inundates consumers with new, trendy marketing ingredients that promise to improve the texture and appearance of skin. Most of these ingredients fade out of the spotlight with time, but there is one that consistently lives up to the hype: hyaluronic acid.
What Is Hyaluronic Acid?
Hyaluronic acid is a naturally occurring material found in the skin that is revered for its ability to hold on to 1,000 times its weight in water. When functioning properly, the skin’s own hyaluronic acid keeps each layer of skin hydrated, stable, and looking its best, but with age, stress, and other environmental stressors, skin is not able to keep itself optimally hydrated on its own.
Hyaluronic acid is a humectant, like aloe and glycerin, which means that it draws moisture from surrounding air. Humectants are often featured in hydrating leave-on skincare products due to their ability to hydrate dry skin.
When used over time, hyaluronic acid has the ability to revitalize the skin’s surface layers, improves the look of fine lines and wrinkles, and makes skin softer, bouncier, and more supple.
While hyaluronic acid is best suited for leave-on skincare products such as serums, masks, and moisturizers, it adds benefits to rinse-off products as well, including our favorite cleanser format: bar soap.
