Hyaluronic acid (HA) is a naturally occurring substance found in the human body, particularly in the skin, eyes, and connective tissues. It is a glycosaminoglycan, which is a type of molecule composed of sugars and amino acids.

Hyaluronic acid plays a crucial role in maintaining moisture and lubrication in various parts of the body. In the skin, it helps retain water, keeping the skin hydrated and plump. It also contributes to the elasticity and firmness of the skin.

Due to its hydrating and lubricating properties, hyaluronic acid has become a popular ingredient in skincare products, particularly in moisturizers, serums, and anti-aging treatments. It is known for its ability to attract and hold onto water molecules, helping to improve skin hydration and reduce the appearance of fine lines and wrinkles.

In addition to its skincare applications, hyaluronic acid is also used in various medical and cosmetic procedures. It can be injected into the skin to add volume and reduce the appearance of wrinkles, making it a common ingredient in dermal fillers. It is also used in ophthalmic surgery, orthopedics, and as a component in some oral supplements.

It’s worth noting that while hyaluronic acid is generally safe for use, it’s always advisable to consult with a healthcare professional or dermatologist before using any new skincare or cosmetic products, especially if you have any specific skin concerns or medical conditions.

Hyaluronic acid (HA) offers several benefits for both skincare and medical purposes. Here are some of the key benefits:

  • Skin hydration: HA is known for its exceptional ability to retain moisture. It can hold up to 1,000 times its weight in water, helping to keep the skin well-hydrated and moisturized. This hydration effect can improve the texture and elasticity of the skin, making it appear plumper, smoother, and more supple.
  • Wrinkle reduction: As we age, the natural production of hyaluronic acid in the skin decreases, leading to a loss of volume and the formation of wrinkles and fine lines. Topical application or injections of HA can help replenish the lost moisture and add volume to the skin, reducing the appearance of wrinkles and making the skin look smoother and more youthful.
  • Skin firmness and elasticity: HA helps maintain the structural integrity of the skin by promoting collagen synthesis. Collagen is a protein that provides strength and elasticity to the skin. By supporting collagen production, HA can improve skin firmness and elasticity, making the skin appear tighter and more toned.
  • Wound healing: HA plays a role in the wound healing process. It helps create an optimal environment for cell migration and tissue repair. By promoting tissue regeneration, HA can aid in the healing of wounds, cuts, and other skin injuries.
  • Joint health: HA is also present in the synovial fluid that lubricates and cushions the joints. It helps reduce friction between bones and acts as a shock absorber. Supplementing with HA or receiving injections of HA-based products can help alleviate joint pain, improve joint mobility, and provide relief for conditions like osteoarthritis.
  • Eye health: HA is found in high concentrations in the vitreous humor of the eye, which helps maintain its shape and provide nourishment to the surrounding tissues. HA-based eye drops or ophthalmic solutions can be used to lubricate and hydrate the eyes, relieving dryness and discomfort.

It’s important to note that individual results may vary, and the effectiveness of hyaluronic acid can depend on various factors, including the formulation, concentration, and application method. Consulting with a healthcare professional or dermatologist is recommended to determine the most appropriate and effective use of hyaluronic acid for your specific needs.

Hyaluronic acid (HA) can be found in various forms, depending on its molecular weight and the way it is formulated for different applications. Here are the three primary forms of hyaluronic acid:

  • High molecular weight hyaluronic acid: This form of HA has a larger molecular size and is often used in topical skincare products such as moisturizers, serums, and creams. High molecular weight HA remains on the surface of the skin and forms a hydrating barrier, helping to improve moisture retention and promote a plump and smooth appearance.
  • Low molecular weight hyaluronic acid: This form of HA has a smaller molecular size and can penetrate deeper into the skin. It is often used in skincare products designed to target specific concerns such as fine lines, wrinkles, and skin elasticity. Low molecular weight HA can penetrate the skin more effectively, providing hydration to the deeper layers and promoting collagen production.
  • Cross-linked hyaluronic acid: Cross-linking refers to the process of chemically modifying hyaluronic acid to create a gel-like substance with a longer duration of action. Cross-linked HA is commonly used in cosmetic procedures such as dermal fillers. The cross-linking process allows the HA to remain in the skin for a longer period, providing volume and filling in wrinkles and lines.

It’s important to note that these different forms of hyaluronic acid serve specific purposes and are used in various applications. The choice of HA form depends on the desired outcome and the method of application, whether it is topical skincare products, injectable fillers, or medical treatments.

It’s always recommended to consult with a healthcare professional or dermatologist to determine the most suitable form and application of hyaluronic acid for your specific needs.


Where do people extract the hyaluronic acid from?
Hyaluronic acid (HA) can be extracted from different sources, including animal tissues and microbial fermentation. The specific source of HA extraction can vary depending on the intended use and the ethical considerations involved. Here are the primary sources of hyaluronic acid extraction:

Rooster combs: Historically, the primary source of hyaluronic acid extraction was rooster combs. The combs of roosters contain a high concentration of HA, and extraction was commonly done by isolating and purifying the HA from these tissues. However, due to ethical concerns and the availability of alternative sources, this method is less common today.

Bacterial fermentation: Currently, the most widely used method for producing hyaluronic acid is through bacterial fermentation. Certain strains of bacteria, such as Streptococcus Equi and Streptococcus Zooepidemicus, are capable of producing hyaluronic acid. These bacteria are cultured in a controlled environment, and the HA is extracted from the fermentation broth. This microbial fermentation method is considered a reliable and sustainable source of hyaluronic acid.

 Plant-based sources: Hyaluronic acid can also be derived from plant-based sources. Some plants, such as wheat germ and soybeans, contain small amounts of hyaluronic acid. However, the extraction yield from these sources is relatively low, making them less commonly used compared to bacterial fermentation.

It’s worth noting that the extraction process involves purifying and refining hyaluronic acid to ensure its quality and safety for use in various applications. Additionally, the hyaluronic acid used in medical and cosmetic procedures, such as dermal fillers, undergoes further modifications and cross-linking processes to enhance its stability and longevity.

The specific sourcing and extraction methods may vary among manufacturers and suppliers of hyaluronic acid products. If you have specific concerns about the source or extraction process of a particular product, it is advisable to reach out to the manufacturer for more information.

How many forms of Hyaluronic Acid?
There are technically three types of hyaluronic acid molecules that are formulated into skincare products: Hydrolyzed Hyaluronic Acid,Sodium Acetylated Hyaluronate. Sodium Hyaluronate

Why do some people say there are 7 kinds of Hyaluronic Acid?
Depending on how and sources of extraction, they are packed with marine water and seven different types of hyaluronic acid are:Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Hyaluronic Acid, Hydrolyzed Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Hydroxypropyltrimonium Hyaluronate.

What is the difference of Hydrolyzed hyaluronic acid and Hyaluronic Acid?
Hydrolyzed Hyaluronic Acid is Hyaluronic Acid that has been broken down into elements small enough to penetrate the skin, It’s moisturizing, but not the most moisturizing option, so it’s best for people who have oily or combination skin, since these skin types want to avoid over-moisturizing.
