The Benefits of Hyaluronic Acid for Skin


Hyaluronic acid is one of the most common ingredients found in cosmetic products. This super little substance helps to improve moisturisation, providing numerous benefits to the skin.

To help you know all about adding this ingredient to your skincare routine, here we’ll cover what hyaluronic acid does, its benefits for the skin, and how to use hyaluronic acid products.

In this guide:

What is hyaluronic acid and what does it do?

Hyaluronic acid is a natural substance in the body that helps keep the tissues and joints lubricated.

It’s a humectant, which means that it attracts water from the air or deeper layers within the skin and holds onto moisture, helping to cushion and lubricate the body’s connective tissues and to keep the skin hydrated. This substance can hold 1,000 times its weight in water, which helps to give the skin volume and reduce the appearance of fine lines.

While hyaluronic acid is found in the eyes, joints, and skin, scientists can also create the substance in the lab.

The moisturising properties of hyaluronic acid make it an effective ingredient in skincare products. The skin has its own moisturising ingredients, known as Natural Moisturising Factor (NMF), but this depletes over time – particularly with exposure to external aggressors.

Hyaluronic acid benefits for skin

As you age, your body produces less hyaluronic acid, reducing skin elasticity and leading to classic ageing signs, such as sagging and fine lines. The main aim of cosmetic hyaluronic acid products is to counteract this effect and provide a boost of hydration.

The main benefits of hyaluronic acid for skin include:

  • Keeps skin moisturised to help prevent dryness and tightness.
  • Helps keep skin’s protective barrier healthy and functioning.
  • Keeps the skin plump and hydrated to help support skin cell turnover.
  • Reduces signs of ageing, such as the appearance of fine lines and wrinkles.
  • Encourages collagen and elastin production to boost skin elasticity and help prevent sagging.
  • Reduces the appearance of some scarring.

How to use hyaluronic acid products

Hyaluronic acid is one of the most popular active ingredients used in cosmetic skincare products. It has a high tolerability and can be combined with many other active ingredients to provide products with various end benefits.

Hyaluronic acid is available in many product formats, from cleansers and serums to moisturisers, and in products for the face, body, and hands, as well as the hair.

Serums are a very popular choice since they tend to contain a higher level of hyaluronic acid and, therefore, are an ideal option for those looking for products for signs of ageing and skin damage. Follow the label instructions to get the most benefits from a serum.

Generally, serums should be applied twice a day after cleansing but before heavier products like creams to allow the active ingredients to penetrate deep into the skin.

Hyaluronic acid cleansers can be used twice a day and as the first step of your skincare routine. These can be followed by toners and serums. Moisturisers containing hyaluronic acid should be applied as your last step and can be used twice daily.

Hyaluronic acid FAQs

What does hyaluronic acid do for skin?

Hyaluronic acid hydrates the skin by attracting and retaining water that has been drawn from the environment or up from deeper layers within the skin. Products containing hyaluronic acid can offer many skin benefits, including reducing the appearance of signs of ageing and scarring, keeping the skin moisturised, preventing tightness, and boosting skin elasticity.

What are the side effects of hyaluronic acid?

Hyaluronic acid is a natural substance in the body, so there are very few side effects associated with it. Allergic reactions are possible but very uncommon. Some over-the-counter prescription drugs may also react with hyaluronic acid, so always read the instructions and ingredients before use.
