How do I use hyaluronic acid, and why do I need it?

You've probably heard the words hyaluronic acid going around a lot in the past year as it has become an incredibly popular ingredient in the skincare industry. The Ordinary use hyaluronic acid in a fair few of their products, including the bestselling Hyaluronic Acid 2% + B5.

Find out why hyaluronic acid is so popular, whether it's suitable for your skin and how you should be using it the feel the maximum benefits.

What is hyaluronic acid?

Hyaluronic acid is a natural substance found in the skin to keep it refreshed, stable and encourages skin cell renewal. However, it's most loved for its incredible water retention properties.

As skin ages, it becomes drier as its ability to retain water lessens, which results in loss of firmness and fine lines. Collagen is mainly made of water and this is exactly what keeps skin looking youthful. When applied, hyaluronic acid will rehydrate skin for a plumper appearance and will minimise the appearance of fine lines and wrinkles.

Hydration isn't the only benefit of hyaluronic acid, it also has antioxidant properties to protect your skin from the environment, sun exposure and harsh chemicals.

Who is hyaluronic acid best for?

One of the best things about hyaluronic acid is that it can benefit all skin types. It's obviously great for dry and mature skin due to its hydrating and anti-aging properties, but it can also help oily complexions. Oily and combination skin types still need hydration, and the lightweight formulation of hyaluronic acid is perfect as it feels weightless on the skin, whilst still providing the much-needed moisture.

Hyaluronic acid is also for sensitive and blemish-prone skin as it helps to calm skin, whilst protecting it with its antioxidant properties. It can also be used safely during pregnancy.

Are there any drawbacks of hyaluronic acid?

Hyaluronic acid is found naturally in the body, so there are no proven side effects to applying it topically. However, because hyaluronic acid's natural purpose is not for hydration, the molecules are often too big for skin absorption. Some brands claim hydration benefits through hyaluronic acid but actually, the product is just sitting on the skin drawing out moisture for temporary benefits.

With The Ordinary and their Hyaluronic Acid 2% + B5, they use three forms of hyaluronic acid in varying molecular weights to ensure it is absorbed providing full hydration, and not just temporary effects.

What other ingredients does Hyaluronic Acid work best with?

Alpha hydroxyl acids provoke skin cell turnover to help exfoliate skin for a brighter and more even skin tone. However, these acids can be drying on the skin, so including hyaluronic acid is a great way to enjoy the benefits of AHA's without dehydrating the skin. The Ordinary Lactic Acid 10% and HA 2% is a good example of this.

Hyaluronic acid also works well alongside other anti-aging ingredients such as vitamin C. The Vitamin C Suspension 23% + HA Spheres 2% contains vitamin C in its purest form which brightens and aids collagen production. This pairing together encourages and protects collagen, whilst hydrating and brightening aging skin.

Where and how should I use Hyaluronic Acid?

Like with any new skincare product, you should start slow with hyaluronic acid, applying it once per day to see how your skin takes to it. If you find your skin is really benefiting from the additional hydration, you should apply it once in the morning and once in the evening. The Hyaluronic Acid 2% + B5 is water-based so should be applied before heavy oils and creams, all over the face.

Many products from The Ordinary contain hyaluronic acid to keep the skin rehydrated. You can browse the entire range from The Ordinary on Adore Beauty to build your perfect skincare routine.
