Hyaluronic Acid (HA)

Hyaluronic Acid (HA)

Hyaluronic acid (HA) is a popular ingredient in the skincare world, known for its incredible hydrating properties. But what exactly is it, how does it work, and where can you find it? Let’s break it down in simple terms.

What Is Hyaluronic Acid?

Hyaluronic acid is a naturally occurring substance in our bodies. It’s a type of molecule called a glycosaminoglycan, which is a fancy way of saying it’s a long chain of sugar molecules. These molecules are particularly good at retaining water, which is why HA is famous for its hydrating abilities. In fact, just one gram of hyaluronic acid can hold up to six litres of water!

How Does Hyaluronic Acid Work?

Imagine hyaluronic acid as a tiny sponge that sits within your skin. When you apply a product containing HA, it draws moisture from the environment into your skin and helps to lock it in. This is especially beneficial for keeping your skin hydrated, plump, and smooth.

Here’s a simple breakdown of how it works:
1. Hydration: HA draws moisture into the skin.
2. Plumping: By attracting water, HA helps to plump up the skin, reducing the appearance of fine lines and wrinkles.
3. Barrier Reinforcement: It helps strengthen the skin’s natural barrier, protecting against environmental damage and dehydration.
4. Healing: It aids in tissue repair and regeneration, making it great for soothing irritated skin.

What Products Is Hyaluronic Acid Found In?

Hyaluronic acid is incredibly versatile and can be found in a wide range of skincare products. Here are some common types:

  • Serums: These are often packed with a high concentration of HA, making them ideal for delivering a strong dose of hydration.
  • Moisturisers: Many moisturisers contain HA to help enhance their hydrating effects and improve skin texture.
  • Sheet Masks: These masks are soaked in HA and other beneficial ingredients, providing an intensive hydration boost.

How Is Hyaluronic Acid Made?

Hyaluronic acid can be derived in several ways:

1. Natural Extraction: Historically, HA was extracted from rooster combs (the red crest on a rooster’s head). However, this method is less common today due to ethical and efficiency reasons.

2. Bacterial Fermentation: The most common modern method involves using bacteria to produce HA. A specific type of bacteria, Streptococcus, is fed a glucose-rich nutrient solution. Through fermentation, these bacteria produce hyaluronic acid, which is then harvested, purified, and used in skincare products.

3. Synthetic Production: Advances in biotechnology have also allowed for the synthetic production of HA, ensuring high purity and consistency.

Why Should You Use Hyaluronic Acid?

If you’re looking for a way to keep your skin hydrated and youthful, hyaluronic acid is an excellent choice. Its ability to retain moisture helps to maintain a healthy skin barrier, reduces the appearance of fine lines, and gives your skin a plump, glowing appearance. Plus, it’s suitable for all skin types, even sensitive or acne-prone skin.


Hyaluronic acid is a superstar ingredient in the skincare world for good reason. Its incredible ability to attract and retain moisture makes it a key player in maintaining hydrated, youthful-looking skin. Whether you’re using a serum, moisturiser, or sheet mask, incorporating HA into your skincare routine can help you achieve a healthy, glowing complexion.
