What is Hyaluronic Acid?

Hyaluronic acid is a naturally occurring substance in the human body, primarily found in the fluids of the eyes and joints. Its main functions include retaining moisture and ensuring proper lubrication and hydration of joint tissues. Additionally, it offers various benefits, such as promoting wound healing.

Hyaluronic Acid Benefits

1. Hyaluronic Acid for Skin: Promotes Smooth and Healthy Skin

Approximately half of the body’s hyaluronic acid is found in the skin, where it binds with water to maintain hydration. Applied topically, it helps reduce wrinkles, redness, and dermatitis. Dermatologists often use hyaluronic acid fillers to keep the skin firm and youthful.

2. Accelerates Wound Healing

Hyaluronic acid naturally occurs in the skin, with its concentration increasing at injury sites to aid repair. Sodium hyaluronate also has antibacterial properties, reducing the risk of infection when applied directly to wounds.

3. For Knee: Relieves Joint Pain

Hyaluronic acid helps maintain proper lubrication between bones, reducing joint pain and improving mobility.

4. Eases Acid Reflux Symptoms

Studies have shown that a mixture of hyaluronic acid and chondroitin sulfate can promote the healing of acid-damaged throat tissues.

5. For Eye: Alleviates Dry Eyes and Discomfort

Eye drops containing 0.2-0.4% hyaluronic acid have been proven to reduce symptoms of dry eyes and improve overall eye health.

6. Supports Bone Strength

7. Prevents Bladder Pain

People Also Ask

1. What is the difference between medical-grade and cosmetic-grade hyaluronic acid?
Medical grade is of higher purity and safety standards and is used in medical applications, while cosmetic grade is more focused on function and end-user perception and is used for routine skin care.

2. What is the difference between food-grade hyaluronic acid and medical-grade oral products?
Food grade is applied to normal foods and falls under loose regulations, while medical grade oral products need more rigorous drug standards, including drug purity and bioavailability testing.

3. Why do hyaluronic acids with different molecular weights have such different effects on skin?
Molecular weight directly affects skin penetration rate and the mechanism of action.

  • High molecular weight mainly forms a moisturizing film on the skin surface;
  • Medium molecular weight can penetrate the stratum corneum;
  • Low molecular weight can reach the dermis to stimulate collagen regeneration;
  • Oligomeric HA (<10kDa) even has cell signaling regulation functions.

4. What is the essential difference between microbial fermentation and animal extraction methods?
The fermentation method uses genetically engineered strains (such as Streptococcus) cultured in a sterile environment, with high product purity and no animal-derived risks; the traditional extraction method extracts from tissues such as rooster combs and is prone to residual heterologous proteins. It has now been phased out by the mainstream market.
