Everything You Need To Know About Hyaluronic Acid
Feel like you hear everyone talking about Hyaluronic Acid but you’re not totally sure what it is? Don’t worry, we’ve got you covered.
We’re here to fill you in on everything you need to know about everyone’s go-to ingredient that’s popping up in everything from cleansers to night creams.
Learn all about what Hyaluronic Acid is, how to use it and why it’s 100% worth adding to your routine.
What is Hyaluronic Acid?
Hyaluronic Acid is a naturally occurring, gel-like substance found in everything from our joints and connective tissue to our eyes and skin. It’s best known for its humectant properties, which means it acts like a moisture magnet.
It draws water to the surface of the skin and locks it in, which keeps skin hydrated and plump.
Are there different types of Hyaluronic Acid?
You might hear Hyaluronic Acid referred to by other names like Hyaluronan or Hyaluronate, which all refer to the same ingredient.
However, there are different weights of Hyaluronic Acid. The smaller the size of the molecules, the more easily they can penetrate through the skin and work deeply.
What is Hyaluronic Acid good for?
Hyaluronic Acid is one of the most well-known active ingredients because of its versatility and ability to support skin health. Its replenishing properties work for all skin types – including sensitive.
Many people reach for Hyaluronic Acid to replenish dry skin, restore their skin barrier and reduce signs of ageing.
This excellent hydrator is also very effective at defending sensitive skin from environmental aggressors like the weather and air pollution.
Best of all, there are no known side effects, so it’s unlikely to cause any irritation - even if your skin can be reactive.
Some of the key skin benefits of Hyaluronic Acid include:
- Hydrating and plumping
- Enhancing radiance
- Improving skin elasticity
- Supporting skin barrier health
- Reducing the look of fine lines and wrinkles
- Defending sensitive skin from environmental stressors

How is Hyaluronic Acid used in Simple® skin care?
We use Sodium Hyaluronate in our skin care products, which is a variety of Hyaluronic Acid that’s composed of smaller molecules. Because of this, it’s able to penetrate the skin more easily.
Like all Simple® products, our formulas that have been infused with Hyaluronic Acid are dermatologically tested, contain no harsh chemicals and are free from alcohol, mineral oils, colour and perfume.
Because our range is designed with sensitive skin in mind, it means that everyone can enjoy the hydration-enhancing benefits of Hyaluronic Acid without worrying about reactions.
How should I add Hyaluronic Acid into my routine?
Gentle cleansers
Using a formula enriched with Hyaluronic Acid can help you cleanse your skin whilst retaining your natural moisture levels. This helps to keep your skin barrier healthy.
Our NEW Active Skin Barrier Care cleansers have been designed to do just that.
Our Replenishing Cream Cleanser is a super effective cream-to-foam formula, enriched with 11% Ceramide Boosters and Hyaluronic Acid. Every cleanse lifts away make-up, pollution and impurities while nourishing and repairing your skin’s natural moisture barrier.
If you’re looking to tackle dullness or breakouts as you hydrate, our Smoothing Gel Cleanser is about to transform your routine. It’s blended with 5% Lactic Acid and Hyaluronic Acid to gently exfoliate while locking in hydration. It resurfaces and refreshes for soft, smooth skin.
Serum
One of the easiest ways to try Hyaluronic Acid for skin is by introducing a serum into your regime. Serums often have higher concentrations of active ingredients like Hyaluronic Acid and can penetrate more deeply into the skin.
Our amazing 3% Hyaluronic Acid & Vitamin B5 Booster Serum regulates sebum production and improves texture, locking in moisture and keeping skin hydrated. It also relieves irritation, making it the perfect partner to calm dry, sensitive skin.
Packed with 3% active ingredients, it contains 0.5% active Hyaluronic Acid, 0.5% active PENTAVITIN™ and 2.5% active Pro-Vitamin B5 – the dream team for soft, plump skin.
Plus, it’s PETA approved and vegan, with 95% naturally derived ingredients.
