Hyaluronic Acid Supplements Can Help Dry, Tight Skin, Says Research

There's a difference between skin feeling tight—as in, firm and lifted—versus skin that's just downright dry and dehydrated. The former feels supple and bouncy. The latter is uncomfortable, irritated, itchy, and maybe even painful. Over time, tight skin may create microcracks in the skin, scaly patches, or flake off. Not ideal, to say the least.

It can happen with age—our epidermis experiences more moisture loss as we get older—but it can also happen from having naturally dry skin or due to your environment, like if you live in cold weather. 

The most common solution people reach for is a richer cream, as they should. Dense lotions with occlusive properties help create a seal around your barrier, trapping in moisture underneath. (Think of these like lush blankets, keeping skin coddled throughout the day and night.) But that film does a whole lot of nothing if you don't have water in the dermis to begin with. 

To its credit, it is a pretty impressive active: Hyaluronic acid, also known as HA or glycosaminoglycan, is a compound similar to collagen created by the human body that serves several important functions. It is the key molecule involved in skin moisture1, meaning it plays a huge role in the skin's aging process. Hyaluronic acid works by1 drawing in water and holding it—up to 1,000 times its weight, making it an incredibly effective and hardworking molecule.

When taken orally, the ingredient helps your skin hold on to water from the inside. "It draws water into the stratum corneum, the top layer of the skin. It is a humectant, so it gives an immediate improvement in the way the skin looks—less ashy, dry, dull," says holistic dermatologist Cybele Fishman M.D.*
