7 Surprising Benefits of Hyaluronic Acid

Hyaluronic acid(透明酸钠), also known as hyaluronan, is a clear, gooey(胶粘的) substance that is naturally produced by your body.

The largest amounts of it are found in yourskin, connective tissue and eyes.

Its main function is to retain water to keep your tissues well lubricated and moist.

Hyaluronic acid has a variety of uses. Many people take it as a supplement, but it’s also used in topical serums, eye drops and injections.

Here are 7 scientifically backed benefits of taking hyaluronic acid.

01

Promotes Healthier, More Supple Skin

Hyaluronic acid supplements can help your skin look and feel more supple.

Roughly(概略的) half of the hyaluronic acid in your body is present in your skin, where it binds to water to help retain moisture.

However, the natural aging process and exposure to things like ultraviolet radiation(紫外线辐射) from the sun, tobacco smoke and pollution can decrease its amounts in the skin.

Taking hyaluronic acid supplements may prevent this decline by giving your body extra amounts to incorporate into the skin.

Doses of 120–240 mg per day for at least one month have been shown to significantly increase skin moisture and reduce dry skin in adults.

Hydrated skin also reduces the appearance of wrinkles(皱纹), which may explain why several studies show that supplementing with it can make skin appear smoother(光滑).

When applied to the surface of the skin, hyaluronic acid serums can reduce wrinkles, redness and dermatitis(皮炎).

(透明质酸，也就是我们所说的玻尿酸可以使肌肤水合，减少皱纹以及细小的干纹，减轻肌肤泛红以及皮肤炎症，但是并不能产生消灭痘痘的作用哦，除非是使用了其他的成分，在单一的以透明质酸为主要组成成分的医美面膜内，并不具备灭痘去闭口的作用)

Some dermatologists even inject hyaluronic acid fillers to keep skin looking firm and youthful.

(这个就是我们常说的注射玻尿酸啦)

02

Can Speed Wound Healing

Hyaluronic acid also plays a key role in wound healing.

It’s naturally present in the skin, but its concentrations increase when there is damage in need of repair.

Hyaluronic acid helps wounds heal faster by (炎症)regulating inflammation levels and signaling（给…发信号) the body to build more blood vessels in the damaged area.

Applying it to skin wounds has been shown to reduce the size of wounds and decrease pain faster than a placebo(安慰剂) or no treatment at all.

Hyaluronic acid also has antibacterial properties(特性), so it can help reduce the risk of infection when applied directly to open wounds.

(这个就是为什么医美面膜被称之为医美面膜的原因，此种面膜主要用于医美后皮肤镇静并促进恢复，医美之后皮肤可能会有很多细小的伤口或者由于被过度刺激而产生的大面积泛红，透明质酸有促进伤口愈合的能力，加速恢复的速度以及对开放伤口有一定的抗炎作用，因此是医美后的最佳选择)

What’s more, it’s effective at combating gum disease(牙龈炎), speeding up healing after tooth surgery and eliminating(消除) ulcers when used topically in the mouth .

While the research on hyaluronic acid serums and gels(凝胶) is promising, there has been no research to determine whether hyaluronic acid supplements can provide the same benefits.

However, since oral supplements boost the levels of hyaluronic acid found in the skin, it’s reasonable to suspect they may provide some benefit.

03

Relieve Joint Pain by Keeping Bones Well Lubricated

Hyaluronic acid is also found in the joints(关节), where it keeps the space between your bones well lubricated.

When the joints are lubricated, the bones are less likely to grind against(相互磨损) each other and cause uncomfortable pain.

Hyaluronic acid supplements are very helpful for people suffering fromosteoarthritis(骨关节炎), a type of degenerative(退化的) joint disease caused by wear(磨损) and tear(撕裂) on the joints over time.

(透明质酸存在于滑膜关节液中，骨关节炎与其他的炎症不同，由于长期反复使用导致的退行性病变，一般是由于年龄增长导致的疾病，注射或者使用透明质酸补充剂都可以在一定程度上缓解症状)

Taking 80–200 mg daily for at least two months has been shown to significantly reduce knee pain in people with osteoarthritis,especially those between the ages of 40 and 70 years old.

Hyaluronic acid can also be injected directly into the joints for pain relief. However, an analysis of over 12,000 adults found only a modest reduction in pain and a greater risk ofadverse effects(副作用).

Some research shows that pairing(配合) oral hyaluronic acid supplements with injections can help extend pain-relieving benefits and increase the amount of time between shots .
