Water-binding ingredient

Hyaluronic acid, a humectant that helps hold moisture

HYALURONIC ACID · HYALURONATE

A widely used humectant that attracts and holds water around the skin to help maintain a moisturised feel. Its label name and feel can vary by form.

01

WHAT IT MEANS

Why is this ingredient used?

Different label names can result when hyaluronic acid is paired with sodium or potassium, adjusted in molecular size, or crosslinked. “Eight types” means eight related ingredients are listed; it does not mean eight times the hydration.

The toner label lists sodium hyaluronate at 1,100 ppm plus seven additional HA-related ingredients.

INGREDIENT NOTES

What should you check about Hyaluronic Acid?

Start with what the name means, then see what was actually verified on the product label.

Do eight types mean eight times the hydration?

No. “Eight types” means that eight different hyaluronic-acid-related ingredients appear on the ingredient list. It does not mean that hydration increases eightfold.

The feel of a formula depends on the amount and form of each material as well as other humectants such as glycerin, oils, texture and the amount applied.

Why the names change with the form

When hyaluronic acid is paired with sodium or potassium, it can appear as Sodium Hyaluronate or Potassium Hyaluronate. Adjusting molecular size or creating a crosslinked structure also results in a different label name.

Different names identify different material forms. The ingredient name alone cannot establish delivery depth or prove that one form is always better.

Amounts verified on product labels

Current retail labels disclose Sodium Hyaluronate amounts for three products. The ppm and percentage figures below express the same amount in different units.

  • Hyaluronic Acid Toner: 1,100 ppm, about 0.11%
  • Hyaluronic Acid Aqua Lotion: 2,050 ppm, about 0.205%
  • PDRN Hyaluronic Acid Soothing Cream: 1,000 ppm, about 0.10%
The label confirms names and declared amounts, but not each material’s molecular weight, source or individual contribution to the finished formula.

VERIFIED FACTS

Ingredient facts, separated clearly

Product-label facts are separated from definitions in authoritative ingredient sources. Undisclosed amounts, raw-material specifications and finished-product effects are not inferred.

What exactly is it?
Hyaluronic acid is a linear glycosaminoglycan made of repeating sugar units; sodium hyaluronate is its sodium salt.
Role in cosmetics
Used in cosmetics as a humectant and skin-conditioning ingredient. A count such as “eight types” does not by itself establish deeper penetration or better hydration.
Verified in these products
The labels declare sodium hyaluronate at 1,100 ppm (0.11%) in the toner, 2,050 ppm (0.205%) in Aqua Lotion and 1,000 ppm (0.10%) in Soothing Cream.
What the label cannot tell us
An ingredient name alone does not disclose molecular weight, raw-material source, formulation purpose or finished-product performance.

EVIDENCE & LIMITS

What the research can support

Evidence scopeHuman evidence exists for specific formulas

A study of specific creams containing 0.1% hyaluronic acid reported improvements in hydration and elasticity measures. It does not directly test these products, whose molecular forms, concentrations and complete formulas differ.

CLEAR ANSWERS

FAQ

When should I use a hyaluronic acid toner?

Use it as the first hydration step after cleansing, then add two or three thin layers if needed.

Are more types of hyaluronic acid always better?

The number alone cannot predict a formula’s feel or moisturising performance. Consider amount, supporting humectants and texture together.

What percentage is 1,100 ppm sodium hyaluronate?

1,100 ppm converts to 0.11%. This is the toner’s declared sodium hyaluronate amount, not the combined total of all eight HA-related ingredients.
