Microbial fermentation remains the most common way to get hyaluronic acid because it is more cost-effective for manufacturers and consumers, and is more eco-friendly because of the reduced production of environmental pollution. Skincare brands usually use plant-based hyaluronic acid, while animal-based hyaluronic acid is usually used in injections and supplements.

If you wonder what does hyaluronic acid do for your skin, here is the list of its benefits:
It has a unique ability to replenish a lot of moisture. Hyaluronic acid penetrates the skin and binds water to skin cells, keeping it hydrated. One gram of hyaluronic acid is able to hold up to six liters of water. As a result, using hyaluronic acid helps your skin look more youthful. Hydrated skin also has fewer wrinkles. It becomes firmer and smoother for a refreshed appearance. In order to increase skin hydration, it is recommended to use a serum.
Hyaluronic acid is also known for its antibacterial properties. it can help reduce the risk of infection when applied to wounds. When you have a skin injury, natural hyaluronic acid contained in your body will also increase in concentration to help repair the injured skin.
Hyaluronic acid improves the ability of the skin to defend against different negative environmental factors and pollutants that age the skin. Since hyaluronic acid occurs naturally in the body, it is not harsh, which means that even people with very sensitive and acne-prone skin can use it without worrying about irritation.
Hyaluronic acid is also able to increase the skin’s elasticity. As our skin ages, it starts losing elastin and collagen known as the building blocks for skin tightness and tone. Hyaluronic acid cannot replace elastin but it boosts the skin’s natural ability to retain moisture, which helps it look tighter and better with its natural plump and glow.
Hyaluronic acid promotes skin cell regeneration by providing hydration and enhancing the skin’s barrier. As a result, you will get a vibrant complexion with reduced wrinkles and fine lines. It also minimizes age spots and prevents the appearance of dark spots in the future.
Hyaluronic acid helps protect the skin from various harmful forces and toxins, including the sun’s rays, pollution, and smoke. It is especially important as you age because your lipid production slows down.
People with mild to moderate eczema notice the reduction in symptoms by using hyaluronic acid-based foam. It is important though to speak with a medical professional first before trying it.

In general, hyaluronic acid products, supplements, and injects are safe if people follow the instructions on how to use them. However, hyaluronic acid may produce allergic reactions and side effects in some people. Therefore, it is always recommended to use a test patch before you start using a new skin product containing this substance.
People receiving injections with hyaluronic acid may experience some side effects that usually disappear within a week. Their side effects include:
However, in most cases, these side effects are a result of the injection process itself rather than hyaluronic acid.
In general, hyaluronic acid rarely causes any side effects because it is naturally produced by our bodies. However, if you have a history of serious allergic reactions, you should be careful when using products containing hyaluronic acid.

Most skincare products use plant-based, vegan-friendly hyaluronic acid produced through microbial fermentation, though some may still use animal-derived sources. The plant-based source of hyaluronic acid is completely vegan and cruelty-free. It is produced by the fermentation of a safe bacterial strain. This is the most common option in skincare products given the cost and the impact on the environment.
The non-vegan source of hyaluronic acid is produced from the red flesh on the top of the rooster’s head. Needless to say, this sourcing option is not vegan. This option has mostly been phased out since the discovery of the plant-based option in the 90s. But if you’re concerned about smearing a rooster-flesh product all over your face, it’s best to check with the product manufacturer if the product isn’t explicitly advertised as vegan.
Sodium hyaluronate, the salt form of hyaluronic acid, has a smaller molecular size, allowing it to penetrate deeper into the skin for enhanced hydration. Its water solubility and smaller molecular structure mean that it has an ability to penetrate deeper into the skin and provide better hydration. It is a component of anti-aging and moisturizing products due to its ability to hydrate the skin, reduce fine lines, and improve firmness levels. Sodium hyaluronate is often found in such cosmetic products as moisturizers and serums. It also has a form of an oral supplement.
Both hyaluronic acid and sodium hyaluronate offer the same benefits. The primary difference between them is that sodium hyaluronate has a smaller molecular size, which allows it to penetrate the skin better.
Hyaluronic acid is especially effective in combination with some other ingredients, including retinol, vitamin C, and glycolic acid. To understand why they all work well together, let’s review first what these ingredients are:
Acne is one of the most common skin disorders that can occur at different phases of our lives. According to scientific research, almost 80% of people experience some sort of acne between the ages of 11 and adulthood. It is usually caused by bacteria, lasting for years, and leave acne scarring. Today, there are many methods to reduce or even eliminate acne scars, and one of the most effective is the use of hyaluronic acid serum.
In order to get rid of the acne scars, you can get treatments with lasers, which are quite effective and give good results. However, it is also possible to use a hyaluronic acid serum that is able to identify water and bind it to skin cells by reducing the collapsed look of acne scars and encouraging healthy tissues over the long term.
However, it is also important to know that hyaluronic acid serums are not good for everyone because they may also contain comedogenic ingredients causing pore-clogging. These ingredients are lanolin (extracted from sheep’s wool) and silicone that traps debris in the skin pores by creating a thin and silky film over the outermost skin layer.
When scouring the long list of hard-to-pronounce ingredients on the product label, it can be hard to pinpoint certain ingredients. Many of the ingredients we cover go by different names! You may also find hyaluronic acid labeled as followed:
