What is Hyaluronic Acid? An Expert Explanation
Hyaluronic acid is a naturally occurring substance in the body that has become increasingly popular in skincare and beauty products.
It is a gooey, slippery substance that is found throughout the body, especially in eyes, joints, and skin.
Hyaluronic acid is known for its hydrating and moisturizing properties and is often used to improve the appearance of fine lines, wrinkles, and dry skin.
Despite its name, hyaluronic acid is not an exfoliating acid like glycolic or salicylic acid. Instead, it is a glycosaminoglycan, a type of molecule that is found in connective tissue.

Chemical Structure of Hyaluronic Acid
Hyaluronic acid is a glycosaminoglycan, which is a type of long, unbranched polysaccharide.
It is a linear polymer made up of repeating disaccharide units composed of D-glucuronic acid and N-acetyl-D-glucosamine. The disaccharide units are linked together by alternating β-1,4 and β-1,3 glycosidic bonds, forming a long chain.
The molecular weight of hyaluronic acid can vary from a few thousand to several million Daltons, depending on the source and method of isolation.
The chemical structure of hyaluronic acid is unique among glycosaminoglycans in that it is not sulphated.
Instead, it contains carboxyl and hydroxyl groups, which can form hydrogen bonds and other non-covalent interactions with water molecules.
This gives hyaluronic acid its characteristic ability to bind and retain water, making it an excellent lubricant and shock absorber in joints and other tissues.
In addition to its role in joint lubrication, hyaluronic acid is also an important component of extracellular matrix in many tissues, including skin, cartilage, and connective tissue.
It is involved in cell adhesion, migration, and proliferation, and has been shown to play a role in wound healing and tissue repair.
The unique chemical structure of hyaluronic acid also makes it a popular ingredient in cosmetic and skincare products. Its ability to bind and retain water can help to hydrate and plump the skin, reducing the appearance of fine lines and wrinkles.
It is also non-toxic and biocompatible, making it a safe and effective choice for topical use.
Role of Hyaluronic Acid in the Body
Hyaluronic acid is a naturally occurring substance in the human body, found in various tissues and fluids, including skin, joints, and eyes. It plays a crucial role in maintaining the overall health and function of these areas.
In the skin, hyaluronic acid is responsible for maintaining moisture levels, which helps to keep the skin hydrated, supple, and elastic.
It achieves this by binding with water molecules and forming a gel-like substance, which fills the spaces between skin cells and provides a cushioning effect.
As people age, the amount of hyaluronic acid in the skin decreases, leading to dryness, wrinkles, and other signs of ageing.
For this reason, hyaluronic acid is a popular ingredient in many skincare products, including moisturisers, serums, and masks.
In the joints, hyaluronic acid acts as a lubricant and shock absorber, helping to reduce friction and wear and tear on the joint surfaces.
It also plays a role in the formation and maintenance of cartilage, which is the smooth, flexible tissue that covers the ends of bones and allows them to move smoothly against each other.
In people with osteoarthritis, the amount and quality of hyaluronic acid in the joints can decrease, leading to pain, stiffness, and reduced mobility. In these cases, injections of hyaluronic acid can help to restore lubrication and reduce inflammation.
In the eyes, hyaluronic acid is found in the vitreous humour, which is the clear, gel-like substance that fills the space between the lens and the retina.
It helps to maintain the shape of the eye and provides a cushioning effect that protects the delicate structures inside.
In addition, hyaluronic acid is used in various eye surgeries, such as cataract removal and corneal transplants, to help promote healing and reduce inflammation.
Overall, hyaluronic acid plays a vital role in maintaining the health and function of various tissues and fluids in the human body.
Its ability to bind with water molecules and form a gel-like substance makes it particularly useful in maintaining hydration and cushioning effects in the skin, joints, and eyes.
Hyaluronic Acid and Skin Health
Hyaluronic Acid in Skincare Products
Hyaluronic acid is a popular ingredient in many skincare products due to its hydrating properties. It is a humectant, which means it attracts and retains moisture, helping to keep the skin plump and hydrated.
When applied topically, hyaluronic acid can help to improve the skin's texture and reduce the appearance of fine lines and wrinkles.
Skincare products that contain hyaluronic acid come in various forms, including serums, moisturisers, and face masks. It is important to note that not all hyaluronic acid is created equal.
Some products may contain a lower concentration of hyaluronic acid, which may not provide the same level of hydration and skin benefits as other products.
Benefits for the Skin
In addition to its hydrating properties, hyaluronic acid has several other benefits for the skin. One of the most significant benefits is its ability to promote collagen production.
Collagen is a protein that is essential for maintaining the skin's elasticity and firmness. As we age, our body's natural collagen production decreases, which can lead to sagging skin and wrinkles.
By promoting collagen production, hyaluronic acid can help to improve the overall appearance of the skin.
Hyaluronic acid also has anti-inflammatory properties, which can help to soothe and calm irritated skin. This makes it an excellent ingredient for those with sensitive skin or conditions such as eczema or rosacea.
Additionally, hyaluronic acid can help to protect the skin from environmental stressors such as pollution and UV rays, which can cause damage and premature ageing.
Overall, hyaluronic acid is a versatile ingredient that can provide many benefits for the skin.
Whether you are looking to hydrate dry skin, reduce the appearance of fine lines and wrinkles, or protect your skin from environmental stressors, hyaluronic acid is worth considering as part of your skincare routine.
