Hyaluronic acid – the moisturising miracle under the magnifying glass

Hyaluronic acid is produced naturally in the body. From a chemical standpoint, it is a chain of sugar molecules with an amazing property: it attracts water magnetically and holds onto it. A single gram of this active ingredient can bind up to 6 litres of water. Amongst other things, it creates a natural lubricant for our joints in the body. In cosmetic products, hyaluronic acid provides sustainable moisture penetration of skin and hair. On the INCI list, you will find this substance under the scientific name sodium hyaluronate or hyaluronic acid.

Wondering whether you can tolerate this ingredient? The good news is: Although its name makes it sound like a potential irritant, there is only a small risk of hyaluronic acid causing allergies and irritation. This is because the substance occurs naturally in our bodies.

Face care with hyaluronic acid that supplies moisture, plumps the skin and can therefore reduce fine lines has been a trend on the beauty scene for a long time. But only very few people know the reason for the hyaluronic acid effect. Because it not only depends on the concentration but also on the length of the hyaluronic acid chains and thus the size of the individual molecules. There are three different types of hyaluronic acid:

• High molecular weight/long chain hyaluronic acid: The molecules are large and are therefore unable to penetrate deep into the skin. They just form a smooth film on the skin, which makes it look plumped up. So this instant effect only lasts for a short time. There is no long-term effect, just a short-term one. A film forms on the skin without penetrating deep down. But this form of hyaluronic acid has anti-inflammatory properties.

• Low molecular weight/short-chain hyaluronic acid: The molecules are smaller and can penetrate the skin’s middle layers. This also enables a long-term effect.

• Oligo hyaluronic acid: This is the smallest form of hyaluronic acid. It can penetrate especially deep into the skin and develop its long-term effect. This form is particularly effective in anti-ageing skincare.

Unfortunately, all three types of hyaluronic acid are identified in the same way on the list of ingredients. For more precise information, you should contact the manufacturer of the product. In addition, the price is also an important indicator of quality. As oligo hyaluronic acid is expensive to manufacture, you will not find it in cheaper products.

As a rule, a concentration of 1% hyaluronic acid is entirely sufficient for short chain or oligo hyaluronic acid. If the content is higher, the product tends to be sticky and feels unpleasant on the skin. Incidentally, the same also happens with the much-praised “instant effect”, especially with high molecular weight hyaluronic acid. Instead of penetrating the skin, the hyaluronic acid lies like a water-retaining film on fine lines and makes them disappear in the short term.

The skin is indeed protected from external influences but the effect of the hyaluronic acid will vanish as soon as you wash your face. A mixture of various forms of hyaluronic acid is therefore best: The larger molecules make the skin look plumper through the instant effect and the small molecules work in the long term.

No wonder this active ingredient is so popular. Because along with its quality as a water magnet and moisture-booster, hyaluronic acid also has anti-inflammatory potential. In addition, it can protect the skin cells from free radicals and support their growth. Hyaluronic acid also contributes positively to normal wound healing.

Collagen is frequently mentioned in connection with hyaluronic acid. You should be aware of the small but important difference between the two substances. Collagen is also produced in the body. Whereas hyaluronic acid primarily provides elasticity, collagen, as a structural protein, firms the skin. Together, both active substances combine their potential and form a virtually unbeatable duo.

It's not hard to introduce hyaluronic acid to your routine because it is a popular ingredient in numerous skincare products. Hyaluronic acid is frequently found in both face serums and in face creams or moisturising masks. This is because it’s not only well tolerated but also combines wonderfully with other active ingredients.

A face serum with hyaluronic acid is a wonderful enhancement to any skincare routine. You simply apply the serum on cleansed skin and then apply your usual face cream and facial oil, if required. Always take care to use watery textures first and finish with a creamy or oily texture. In this way you ensure that the valuable ingredients in your serum are locked into the skin, where they can take effect.
