What is hyaluronic acid ?
Hyaluronic acid is actually a natural structural component of skin, and, in fact, is present in connective tissue throughout the human body. Hyaluronic acid (also known as hyaluronan) is a glycosaminoglycan, a type of molecule composed partly of sugars.
Present in large amounts in the spaces between skin cells, where it provides moisture, plumpness, firmness and suppleness to the skin.
It is of the chief components of the extra-cellular matrix (the tissue that provides structural support to cells). In short, hyaluronic acid supports many important areas of the body, with notable benefit to joints and skin.
Hyaluronic acid is also a “smart nutrient” as it can adjust its moisture absorption rate based on the humidity—relative to the season and the climate.
Unlike collagen, Hyaluronic Acid is able to penetrate the skin’s upper layers to improve and benefit the skin when applied topically. This is thanks to its small molecular size.
Hyaluronic acid is a major component of skin, where it benefits tissue repair and protection.
What makes it a great ingredient in skincare?
First off, don’t let the word “acid” fool you. Hyaluronic acid isn’t harsh or skin-stripping at all. In fact, it’s the exact opposite—a powerful humectant (aka moisture-binding ingredient) that keeps skin plump and hydrated and, yes, young-looking. When you apply it topically it penetrates the dead cell layer (stratum corneum) and permeates the skin It increases hydration, improves elasticity and also reverses free radical damage, so it may have some benefit in protecting from UV damage
As we age, our skin loses moisture, resulting in a loss of firmness and pliability. hyaluronic acid and sodium hyaluronate can reduce the appearance of fine lines, promote younger-looking skin, and help create a healthier barrier.
While it won’t give you the dramatic, instantaneous results that a hyaluronic acid filler can, you will see benefits in the form of softer, smoother, more hydrated skin.
