What is it?
Hyaluronic acid wasn't always known as a skincare ingredient; it was actually discovered 60 years ago in vitreous humor, which is the clear liquid that fills the eyeball between the retina and the lens. It's also found within connective tissue and joints, where it acts as a natural lubricant. When it comes to skin, "Hyaluronic acid is a structural component... that creates volume and shape," explains FDA Consumer magazine.
Skin benefits
While hyaluronic acid is ubiquitous in young, healthy skin, aging, smoking and a poor diet can all contribute to lower levels over time. In the facial area, this leads to wrinkles and sagging around the eyes, mouth and cheeks and an overall loss of elasticity. Fortunately, scientists have discovered how to harness hyaluronic acid as a skincare ingredient, taking advantage of its natural ability to help the skin absorb moisture. Also, clinical studies report that hyaluronic acid helps wounds heal faster and can minimize the look of scars.
Where to find it
- Topical products. Because hyaluronic acid helps skin retain moisture, it's often found in moisturizers and anti-aging creams for the face and body.
- Injectable fillers. Hyaluronic acid is commonly used in temporary injectable fillers (e.g., Restylane), which reduce the appearance of lines, crow's feet, depressions and acne scars. While these fillers are effective in creating a younger-looking appearance, they're relatively expensive, must be administered by a doctor and need to be repeated several times a year to maintain results.
- Oral supplements. You can also take hyaluronic acid in the form of an oral supplement to repair tissues and reduce joint pain and arthritis. According to registered pharmacist Suzy Cohen, R.Ph., hyaluronic acid oral supplements can help the body maintain moisture, bringing relief for skin problems such as dryness, eczema and psoriasis. Dr. Cohen suggests sticking to the lowest effective dose, about 100 mg once or twice a day with food. Be sure to talk to your doctor before taking any supplements.

Who should avoid it
Hyaluronic acid is ideal for all skin types, particularly dry skin. As with any skincare product, first do a patch test, because additional ingredients in the product might irritate your skin. If you experience redness or irritation, discontinue use.
Also, if you live in an area with low humidity, you may want to avoid using hyaluronic acid, because, "it will sit unabsorbed on the surface of your skin and may actually dehydrate it, drawing out moisture," according to Real Simple.
