hyaluronic acid: Uses, Side Effects, Interactions and ...

喜欢这样的分析:

Likely Effective for:

• Cataracts. Injecting hyaluronic acid into the eye is effective when used during cataract surgery by an eye surgeon.
• Sores in the mouth. Hyaluronic acid is effective for treating mouth sores when applied to the skin as a gel.

Possibly Effective for:

• Aging skin. Some research suggests that injecting a specific hyaluronic acid product (Juvéderm Ultra Plus, Allergan) into smile lines reduces the lines for up to one year.
• Osteoarthritis. Hyaluronic acid might be effective for stiffness and joint pain when injected into the joint by a healthcare provider. Despite being approved by the FDA for treatment of osteoarthritis by injection, results vary. Some people report a moderate improvement in joint stiffness and pain decrease with hyaluronic acid treatment, but this is not always the case. Whether hyaluronic acid might delay or lessen progressive joint damage with long-term use is unknown.

Insufficient Evidence for:

• Dry eye. Early research shows that applying a specific hyaluronic acid eye drop (Hyalistil) might relieve dry eye.
• Eye trauma. Some research suggests that hyaluronic acid might be injected into the eye to treat detached retina or other eye injuries.
• Healing skin wounds and burns. Early research suggests that applying hyaluronic acid to the skin might be helpful for treating burns and skin wounds.

More evidence is needed to rate the effectiveness of hyaluronic acid for these uses.
