Hyaluronic acid (HA) is truly impressive when it comes to attracting and retaining moisture. As a humectant, it has the incredible ability to hold up to 1,000 times its weight in water, making it a highly effective hydrating agent for the skin. When applied topically, it works wonders by replenishing moisture and strengthening the skin's protective moisture barrier, resulting in a visibly smoother, plumper, and more supple complexion. What's fascinating is that the different molecular weights of hyaluronic acid determine how deeply it penetrates the skin and its overall effectiveness. Also, HA is valuable for individuals with acne-prone dehydrated skin, as HA provides lightweight hydration without clogging pores, while also offering relief from inflammation without triggering breakouts.
