Hyaluronic acid serves essential roles in the body, including providing moisture to the skin, eyes, and joints. Its functions encompass retaining skin moisture, contributing to skin suppleness, supporting joint health, and lubricating the eyes. As people age, the skin’s natural moisture decreases, leading some individuals to opt for hyaluronic acid supplementation. This can be in the form of oral supplements, topical skincare products, or injections, all aimed at maintaining skin hydration, promoting joint mobility, and potentially reducing signs of aging. It’s crucial to consult with healthcare professionals before starting any supplementation or cosmetic procedures.
Hydrates and Rejuvenates Skin
Hyaluronic acid is frequently employed in skincare formulations to enhance skin suppleness, and a substantial body of evidence indicates its effectiveness. For instance, a limited-scale investigation revealed that individuals who used a combination of hyaluronic acid serum and lotion, followed by a hyaluronic acid cream twice daily, exhibited visibly smoother, more hydrated, and elastic skin after two weeks. Noteworthy enhancements in wrinkle reduction, skin hydration, and firmness were observed over an eight-week course of the treatment, as outlined in the study.
Hyaluronic Acid Heals Wounds
Within the body, hyaluronic acid plays a crucial role in each phase of wound healing by contributing to the regulation of inflammation and the promotion of tissue growth. As a commercial product, it seems to possess some therapeutic properties. In a particular study, the application of gauze infused with hyaluronic acid to venous leg ulcers in 50 individuals was found to accelerate the healing process compared to the use of gauze alone. Furthermore, studies suggest that the topical application of hyaluronic acid inside the oral cavity may aid in the healing of ulcers and the reduction of post-dental surgery pain.
Lighten Acne Scars
Certain research indicates that hyaluronic acid may enhance the appearance of acne scars. In one study, individuals with acne scars who incorporated topical hyaluronic acid alongside carbon dioxide laser resurfacing, a skin treatment utilizing laser light pulses, experienced more favorable outcomes compared to those who underwent carbon dioxide laser resurfacing alone.
Moreover, evidence suggests that hyaluronic acid injections can contribute to the lightening of acne scars. Studies have shown that the appearance of moderate to severe acne scars demonstrated improvement when hyaluronic acid was injected two or three times, with a four-week interval between each injection.
Relieves Dry Eye Symptoms
Eye drops stand out as the prevailing remedy for dry eye, a condition characterized by insufficient tear production to adequately lubricate the eyes. A significant number of these drops incorporate hyaluronic, and research indicates their efficacy in treating the condition, particularly when the drops contain hyaluronic concentrations ranging from 0.1% to 0.4%.
Furthermore, the acid exhibits the potential to avert insufficient tear production when integrated into contact lenses. Similarly, applying this substance to the eyes before and after cataract surgery may serve as a preventive measure against the induction of dry eye resulting from the procedure.
Reduces Joint Pain
Naturally occurring hyaluronic acid plays a crucial role in diminishing and preventing joint pain by reducing inflammation and providing a cushioning effect that minimizes friction at the juncture of bones. Studies indicate that the intake of the supplements can offer relief from mild knee pain associated with osteoarthritis, a progressive condition where joint tissues deteriorate over time.
However, contrasting findings emerge regarding the efficacy of hyaluronic acid injections, also known as viscosupplementation, in significantly alleviating knee pain compared to a placebo. The observed marginal reduction in pain, coupled with the identified potential for serious adverse events associated with the injections, prompts researchers to scrutinize whether the benefits outweigh the associated risks.
