Hyaluronic Acid

What is Hyaluronic Acid?

Hyaluronic acid (HA) is a naturally occurring substance found in the human body, particularly in the skin, joints, and connective tissues. It is a glycosaminoglycan, which is a type of molecule that helps to retain water and provide lubrication to various parts of the body.

Hyaluronic acid is a large, gel-like molecule composed of repeating units of disaccharides (sugar molecules) called glucuronic acid and N-acetylglucosamine. It has a unique ability to bind and hold water molecules, which contributes to its exceptional hydrating properties.

In the skin, hyaluronic acid plays a crucial role in maintaining moisture balance, promoting elasticity, and providing structural support. It acts as a natural humectant, attracting and retaining water to keep the skin hydrated, plump, and supple. Young and healthy skin has abundant levels of hyaluronic acid, but its production gradually declines with age, leading to drier and less resilient skin.

Due to its hydrating and anti-aging properties, hyaluronic acid is widely used in skincare products such as moisturizers, serums, masks, and dermal fillers. It can be derived from natural sources or produced synthetically. When applied topically, hyaluronic acid helps to replenish moisture, reduce the appearance of fine lines and wrinkles, and improve overall skin texture.

What are the sources of Hyaluronic Acid?

Hyaluronic acid can be derived from various sources, including:

Rooster Combs:

Historically, hyaluronic acid was extracted from the combs of roosters. However, this source is less common nowadays due to ethical concerns and the availability of alternative methods.

Bacterial Fermentation:

The most common method of producing hyaluronic acid is through bacterial fermentation. Bacteria such as Streptococcus zooepidemicus or Bacillus subtilis are genetically modified to produce hyaluronic acid. These bacteria are grown in a nutrient-rich fermentation medium, and as they multiply, they naturally secrete hyaluronic acid. The hyaluronic acid is then extracted and purified for use in skincare products.

Manufacturing hyaluronic acid through bacterial fermentation is the most widely used method due to its efficiency and scalability. It also ensures a consistent and reliable source of hyaluronic acid.

Once extracted, hyaluronic acid undergoes purification processes to remove impurities and achieve the desired molecular weight for specific applications. The molecular weight of hyaluronic acid determines its penetration into the skin and its overall texture.

It's important to note that the hyaluronic acid used in skincare products is typically produced through a controlled manufacturing process to ensure quality, safety, and purity.
