Have you ever noticed the multitude of products containing hyaluronic acid on the shelves of beauty stores? Have you wondered why this molecule is so prized and how to choose the type suitable for your skin? Is hyaluronic acid really the key to hydrated and youthful skin? Let's explore together the different forms of this miracle ingredient and discover how to select the ideal product to meet your specific needs.
Understanding the different forms of hyaluronic acid
Hyaluronic acid comes in several forms, each having unique properties depending on its molecular weight and formulation. These variations influence how the skin absorbs and reacts to the ingredient.
By molecular weight
The molecular weight of hyaluronic acid determines its ability to penetrate the skin and its effectiveness in hydrating different layers of the skin.
Very high molecular weight hyaluronic acid (< 1,800 kDa)
This acid mainly remains on the surface of the skin, forming a protective film that prevents water evaporation. It provides immediate hydration and a visible smoothing effect.
Intermediate molecular weight hyaluronic acid (1,000 - 1,800 kDa)
Thanks to its small size, it penetrates deeper into the dermis, helping to retain moisture and promoting the body's natural production of hyaluronic acid.
Low molecular weight hyaluronic acid (< 1,000 kDa)
Lighter, this hyaluronic acid easily penetrates the deep layers of the skin, stimulating collagen production and reducing the appearance of wrinkles and fine lines.
Multi-molecular hyaluronic acid
This formula combines different sizes of molecules to ensure hydration at multiple levels of the skin, thus providing a comprehensive solution for various skin types and needs.
By type of formulation
Besides the molecular weight, the formulation of hyaluronic acid plays a crucial role in its effectiveness and compatibility with your skin.
Raw hyaluronic acid (INCI: Hyaluronic Acid)
It is the pure form of hyaluronic acid, known for its strong moisturizing capacity. However, due to its large molecular size, it remains on the surface of the skin.
Hydrolyzed Hyaluronic Acid (INCI: Hydrolysed Hyaluronic Acid)
Thanks to hydrolysis, this form is broken down into smaller fragments, facilitating better penetration and deeper hydration.
Alkaline hyaluronic acid (INCI: Sodium Hyaluronate)
Stabilized in the form of salt, this hyaluronic acid is easier to incorporate into cosmetic formulations and offers more effective absorption compared to the raw form.
Cross-linked hyaluronic acid (INCI: Sodium Hyaluronate Crosspolymer)
This innovative form is designed to create a stable structure while maintaining the moisturizing properties of medium and large-sized molecules.
Acetylated hyaluronic acid (INCI: Sodium Acetylated Hyaluronate)
As a result of a chemical modification, this variant combines hydrophilic and lipophilic properties, providing improved absorption and prolonged hydration.
Plant-based hyaluronic acid
Obtained through bio-fermentation of grains such as wheat or corn, this form is a natural alternative particularly suitable for sensitive skin.
Synthetic hyaluronic acid
Chemically produced, it is primarily used for medical injections due to its ability to effectively fill wrinkles.
The specific uses of each type of hyaluronic acid
Each form of hyaluronic acid addresses specific skincare needs. Here’s how the different formulations can be used to optimize your beauty routine.
Deep hydration
Low and very low molecular weight hyaluronic acid is ideal for penetrating the deep layers of the skin, ensuring long-lasting hydration and plumping the skin from within.
Smoothing and anti-aging effect
Very high molecular weight hyaluronic acid remains on the surface, creating a protective barrier that immediately smooths wrinkles and fine lines, while protecting the skin from external aggressions.
Collagen stimulation
Alkaline hyaluronic acid and multi-molecular hyaluronic acid promote the natural production of collagen, thereby enhancing the elasticity and firmness of the skin.
Filling of wrinkles
Cross-linked hyaluronic acid and acetylated hyaluronic acid are often used in aesthetic treatments to fill wrinkles and restore lost volume, providing visible and long-lasting results.
Specific care
Plant-based hyaluronic acid is perfect for sensitive or reactive skin, while synthetic hyaluronic acid is reserved for medical uses such as injections for precise correction of imperfections.
Note: The combination of different forms of hyaluronic acid in the same formula can provide comprehensive coverage, ranging from superficial hydration to deep collagen stimulation.
Tips for choosing the right hyaluronic acid according to your needs
Choosing the right type of hyaluronic acid requires a good understanding of your skin's specific needs and the properties of the different formulations available on the market.
Identify your skin type
Before selecting a product, it is essential to determine your skin type: dry, oily, combination, or sensitive. Dry skin will particularly benefit from low molecular weight hyaluronic acids for deep hydration, while oily skin may prefer lightweight formulas with intermediate molecular weight acids.
Define your care objectives
Do you simply want to hydrate your skin or are you looking to reduce the appearance of wrinkles and fine lines? For an anti-aging effect, choose cross-linked or acetylated hyaluronic acids that provide visible results by filling in wrinkles.
Choose based on molecular weight
A comparative table can help you visualize which form of hyaluronic acid is best suited to your needs:
| Type of Hyaluronic Acid | Molecular Weight | Main Effect | Ideal Use |
|---|---|---|---|
| Very high molecular weight | 1 800 kDa | Superficial hydration, immediate smoothing | Dehydrated skin, UV protection |
| Intermediate molecular weight | 1,000 - 1,800 kDa | Deep hydration, collagen stimulation | Mature skins, anti-wrinkle |
| Low molecular weight | <1,000 kDa | Deep hydration, plumping | Scars, deep wrinkles |
| Multi-molecular | Various | Hydration at multiple levels | All skin types |
| Acetyl | Variable | Enhanced absorption, prolonged hydration | Aging skin, areas with wrinkles |
| Vegetal | Variable | Natural hydration, suitable for sensitive skin | Sensitive skin, organic formulations |
| Reticulated | Variable | Filling of wrinkles, restoration of volume | Aesthetic treatments, wrinkle filling |
Formulation tailored to your needs
Next, choose products whose formulation meets your expectations. For example, a serum containing low molecular weight hyaluronic acid will be more effective for filling in wrinkles, while a day cream with multi-molecular hyaluronic acid will provide balanced hydration.
Avoid common mistakes
It is easy to make a mistake in choosing a product based solely on advertising or trends. Make sure to read the labels and understand the ingredients to avoid overloaded formulations or those unsuitable for your skin type.
Comparison of brands and products available on the market
The market is full of products containing different forms of hyaluronic acid. Here is a comparative table of some popular brands and their formulations:
| Brand | Type of Hyaluronic Acid | Molecular Weight | Advantages | Price (€) |
|---|---|---|---|---|
| Typology | Sodium Hyaluronate, Acetylated Acid | Intermediate, Low | Deep hydration, anti-aging | 18.50 to 28.50 |
| Rexaline | Base, Multi-molecular, Plant | Mixed | Hydration at multiple levels | Varies by product |
| Clinique XYZ | Reticulated | Variable | Filling of wrinkles, restoration of volume | From 50 |
Attention: Prices may vary depending on specific formulations and points of sale. Always compare ingredients and reviews before making a purchase.
Maximizing the effectiveness of hyaluronic acid in your skincare routine
To make the most of hyaluronic acid, wisely integrate it into your skincare routine. Apply it to slightly damp skin to optimize absorption, and combine it with other moisturizing actives like vitamin B5 or peptides to enhance its effects.
Note: Daily use of hyaluronic acid can prevent skin dehydration and maintain its elasticity, but it is essential to follow it with a moisturizer to seal in moisture.
Conclusion
Choosing the right type of hyaluronic acid can transform your skincare routine and reveal more hydrated, plump, and youthful skin. By understanding the differences between the available forms and selecting those that best meet your specific needs, you can maximize the benefits of this versatile ingredient. Feel free to experiment with different formulations and consult experts to find the perfect solution for your skin.
