Hyaluronic acid can also be injected directly into the joints for pain relief. Taking 80–200 mg daily for at least 2 months has been shown to significantly reduce knee pain in people with osteoarthritis, especially those between the ages of 40 and 70 years old ( 23, 24). Hyaluronic acid supplements are very helpful for people with osteoarthritis, a type of degenerative joint disease caused by wear and tear on the joints over time. When the joints are lubricated, the bones are less likely to grind against each other and cause uncomfortable pain. Hyaluronic acid is also found in the joints, where it keeps the space between your bones lubricated ( 22). Relieve joint pain by keeping bones lubricated It’s unknown whether supplementing with it would have the same effect.ģ. SummaryĪpplying hyaluronic acid directly to an open wound can help speed up the recovery process. However, since oral supplements boost the levels of hyaluronic acid found in the skin, it’s reasonable to suspect they may provide some benefit. While the research on hyaluronic acid serums and gels is promising, there has been no research to determine whether hyaluronic acid supplements can provide the same benefits. What’s more, it’s effective at reducing gum disease, speeding up healing after tooth surgery, and eliminating ulcers when used topically in the mouth ( 21). Hyaluronic acid also has antibacterial properties, so it may help reduce the risk of infection when applied directly to open wounds ( 19, 20). In some older studies, applying it to skin wounds has been shown to reduce the size of wounds and decrease pain faster than a placebo or no treatment at all ( 15, 16, 17, 18). Hyaluronic acid helps wounds heal faster by regulating inflammation levels and signaling the body to build more blood vessels in the damaged area ( 13, 14). It’s naturally present in the skin, but its concentrations increase when there is damage in need of repair. Hyaluronic acid also plays a key role in wound healing. Topical treatments can soothe redness and dermatitis, while injections can make skin appear firmer. Hyaluronic acid supplements can help increase skin moisture and reduce the appearance of fine lines and wrinkles. Some dermatologists even inject hyaluronic acid fillers to keep skin looking firm and youthful ( 11, 12). When applied to the surface of the skin, hyaluronic acid serums can reduce wrinkles, redness, and dermatitis ( 8, 9, 10). Hydrated skin also reduces the appearance of wrinkles, which may explain why several studies show that supplementing with it can make skin appear smoother ( 6, 7). Taking hyaluronic acid supplements may prevent this decline by giving your body extra amounts to incorporate into the skin ( 4, 5).Īccording to one 2014 study, doses of 120–240 milligrams (mg) per day for at least 1 month have been shown to significantly increase skin moisture and reduce dry skin in adults ( 3). However, the natural aging process and exposure to things like ultraviolet radiation from the sun, tobacco smoke, and pollution can decrease its amounts in the skin ( 2, 3). Hyaluronic acid is a compound found naturally in the skin, where it binds to water to help retain moisture ( 1). Hyaluronic acid supplements can help your skin look and feel more supple.
