From the inside out, hyaluronic acid works like a charm to help promote lasting skin health and beauty, and nourish joints for a lasting active lifestyle.

Hyaluronic Acid – HA, first isolated and identified in 1934, is becoming a popular ingredient in actives for young people who embrace “beauty from the inside” and middle-aged adults who don’t slow down and want something more economical with glucose Dosage forms of amines and chondroitin.

The researchers say HA has the following functions in the body: hydrating, lubricating joints, filling spaces and helping to regulate specific aspects of tissue repair, such as activating inflammatory cells to enhance an appropriate immune response. The “beauty” of HA is that it can also be used effectively on the skin. HA occurs naturally in our bodies, and each HA molecule is said to be able to comfortably hold 1,000 times its own weight in water, a key feature sought after by women (and men) as it produces younger-looking skin skin.

Liyoung Hyaluronic Acid for the skin

The authors of the HA Research Review explain that their thorough analysis showed that various HA-based topical formulations “demonstrate significant anti-wrinkle, anti-nasolabial fold, anti-aging, space filling and facial rejuvenation properties. This is achieved through soft tissue enhancement. , Improved skin hydration, collagen and elastin stimulation, and facial volume restoration. HA, alone or in combination with lidocaine and other adjuvants, is used in skin firming and elasticity, facial rejuvenation, improving aesthetic scores, Shows good results in reducing wrinkle scars, prolonging life and rejuvenating tear troughs.”

The mobile benefits of high availability

With age, the body produces synovial fluid at a slower rate, and HA represents an important part of synovial fluid, which helps maintain the viscosity of the fluid (allowing joints to move easily) and supports joint integrity. According to the researchers, it does this “by reducing inflammation and protecting the normal cartilage matrix.” For example, in the case of osteoarthritis, the amount of synovial fluid decreases, which often produces pain.

Less talked about is the positive impact HA has on eye health through drops. This is where many of the innovations in research and development in the natural products industry come into play.

A study validated the benefits of HA eye drops for dry eye. The researchers evaluated the effect of hyaluronic acid eye drops on epithelial wound healing in patients with moderate and severe dry eye for 7 days in 56 patients with moderate and severe dry eye. Lissamine green scores were statistically significantly improved, and all contact lens wearers reported improved lens tolerance.

“The use of hyaluronic acid is an effective treatment for dry eye,” said the researchers. “Severe cases of dry eye in particular show a significant reduction in the number of epithelial lesions. Hyaluronic acid is known to interact with the CD44 receptor on epithelial cells, and through Stimulates cell migration, proliferation and differentiation to promote wound healing.”

Liyoung can provide three grades of hyaluronic acid in food, cosmetic and eye drops, ranging from 0.20×105 – 2.50×106 Da. Hyaluronic acid of different molecular weights have different functions:

HA with different molecular weights

MW range


Ordinary MW


Keeps skin hydrated and lubricated for a long time.

low molecular weight


It is easily absorbed by the skin and
increases skin nutrition.
