Why does XO contain hyaluronic acid (HA)?

When it comes to skincare, few ingredients are as beloved as HA.

Known for its intense hydrating properties, hyaluronic acid has the ability to hold up to 1,000 times its weight in water, making it a powerful moisturizer that leaves the skin plump, smooth, and radiant. But what many people don’t know is that not all hyaluronic acid is created equal. There are different molecular weights of hyaluronic acid, and each one has unique properties that can affect how the ingredient performs on the skin.

In this blog, we’ll break down the science behind hyaluronic acid, explain the importance of molecular weight in skincare, and show you why using products with multimolecular hyaluronic acid can maximize your skin’s hydration, health, and overall glow.

What Is Hyaluronic Acid?

Hyaluronic acid is a naturally occurring molecule found in our skin, eyes, and connective tissues. It’s known for its remarkable ability to attract and retain water, which helps keep our skin hydrated and our joints lubricated. In skincare, hyaluronic acid is primarily used as a humectant, meaning it attracts moisture to the skin, making it ideal for hydration.

As we age, our natural levels of hyaluronic acid decline, contributing to common signs of aging such as dryness, fine lines, and wrinkles. By using skincare products formulated with hyaluronic acid, we can help replenish the skin’s moisture, improving elasticity, reducing the appearance of wrinkles, and promoting a youthful, radiant complexion.

The Importance of Molecular Weight in Hyaluronic Acid

The term molecular weight refers to the size of a molecule. In skincare, hyaluronic acid comes in different molecular weights, typically categorized as high, medium, and low. The molecular weight of hyaluronic acid affects how deeply it can penetrate the skin and, ultimately, how it hydrates the skin.

Each molecular weight serves a different purpose in skincare:

1. High Molecular Weight Hyaluronic Acid: Large molecules that sit on the skin’s surface to provide immediate hydration and form a protective barrier.

2. Medium Molecular Weight Hyaluronic Acid: Smaller molecules that penetrate slightly deeper, providing moderate hydration and helping to improve the skin’s elasticity.

3. Low Molecular Weight Hyaluronic Acid: Tiny molecules that penetrate deeply to deliver intense hydration, encourage collagen production, and support long-term skin health.

When combined, these different molecular weights create what’s known as multimolecular hyaluronic acid. This layered approach to hydration allows the skin to benefit from hyaluronic acid on multiple levels, resulting in better, more comprehensive skincare results.

High Molecular Weight Hyaluronic Acid: Surface Hydration and Barrier Support

High molecular weight hyaluronic acid has the largest molecules and sits on the outermost layer of the skin, known as the stratum corneum. This layer acts as a protective barrier, defending the body against environmental factors like pollution, UV rays, and bacteria.

By forming a thin layer on the skin’s surface, high molecular weight hyaluronic acid serves two primary functions:

• Immediate Hydration: Because it sits on the surface, this form of hyaluronic acid offers immediate moisture, leaving the skin feeling soft and smooth. It provides an instant plumping effect that makes fine lines appear less noticeable.

• Barrier Protection: By holding moisture on the skin’s surface, it helps prevent water loss and supports the skin barrier, which is essential for maintaining healthy skin.

While high molecular weight hyaluronic acid provides essential surface hydration, it can only do so much on its own. For more effective and long-lasting hydration, we need hyaluronic acid with smaller molecules to penetrate deeper into the skin.

Medium Molecular Weight Hyaluronic Acid: Hydration and Elasticity Improvement

Medium molecular weight hyaluronic acid is smaller than high molecular weight HA, allowing it to penetrate slightly deeper. This type of hyaluronic acid provides a balance between surface hydration and deeper moisturization, making it particularly beneficial for improving elasticity.

When applied to the skin, medium molecular weight hyaluronic acid:

• Provides Lasting Hydration: Its molecules penetrate past the skin’s surface but remain close enough to deliver long-lasting moisture. This helps keep the skin soft and hydrated throughout the day.

• Improves Elasticity: Medium molecular weight hyaluronic acid has been shown to improve the skin’s elasticity, helping it feel firmer and more resilient. This is especially beneficial for mature skin, which tends to lose elasticity with age.

For those dealing with dull, dehydrated, or aging skin, medium molecular weight hyaluronic acid is an effective ingredient that promotes hydration without feeling too heavy on the skin.

Low Molecular Weight Hyaluronic Acid: Deep Hydration and Collagen Support

Low molecular weight hyaluronic acid has the smallest molecules, allowing it to penetrate the skin’s deepest layers, where it provides the most intense hydration and supports collagen production. This is the most potent form of hyaluronic acid in terms of anti-aging benefits.

Key benefits of low molecular weight hyaluronic acid include:

• Deep Hydration: By reaching the deeper layers of the skin, low molecular weight HA provides hydration at a cellular level. This promotes a plumper, more youthful appearance and helps reduce the appearance of fine lines and wrinkles.

• Stimulates Collagen Production: Collagen is a protein that provides structure and firmness to the skin. Low molecular weight hyaluronic acid has been shown to stimulate collagen synthesis, which is vital for maintaining youthful, resilient skin.

• Long-Term Benefits: Low molecular weight hyaluronic acid works from within to support the skin’s structure, providing long-lasting hydration that contributes to a healthier complexion over time.

The Benefits of Multimolecular Hyaluronic Acid

Using hyaluronic acid in multiple molecular weights, also known as multimolecular hyaluronic acid, allows you to maximize the benefits of this powerhouse ingredient. By targeting different layers of the skin, multimolecular hyaluronic acid provides comprehensive hydration, supporting surface moisture, elasticity, and deep structural hydration.

Benefits of multimolecular hyaluronic acid include:

1. Comprehensive Hydration: Different molecular weights ensure that every layer of the skin is hydrated, from the surface to the deep layers. This provides an immediate plumping effect and long-term moisture retention.

2. Enhanced Elasticity and Firmness: The combination of medium and low molecular weight hyaluronic acid promotes elasticity and supports collagen synthesis, helping the skin look firmer and more youthful.

3. Improved Skin Barrier: High molecular weight hyaluronic acid on the surface helps reinforce the skin barrier, making it more resilient against environmental damage and moisture loss.

4. Balanced, Youthful Appearance: By delivering hydration at every layer, multimolecular hyaluronic acid addresses multiple signs of aging, such as fine lines, sagging, and dryness. The result is a more radiant, balanced, and youthful complexion.

How to Use Multimolecular Hyaluronic Acid in Your Skincare Routine

To get the most out of multimolecular hyaluronic acid, it’s important to use it correctly:

1. Apply to Damp Skin: Hyaluronic acid works best when applied to slightly damp skin. This allows it to attract moisture more effectively, locking in hydration.

2. Follow with a Moisturizer: After applying a hyaluronic acid serum, seal in the moisture with a good moisturizer. This helps prevent water loss and enhances the hydration benefits.

3. Use Morning and Night: Hyaluronic acid is gentle enough to be used twice daily. Apply it in the morning to hydrate and protect, and at night to repair and rejuvenate the skin.

4. Combine with Other Ingredients: Multimolecular hyaluronic acid pairs well with ingredients like vitamin C, peptides, and ceramides. These ingredients work synergistically to provide additional anti-aging and hydration benefits.

The Future of Skincare with Multimolecular Hyaluronic Acid

The development of multimolecular hyaluronic acid represents a major advancement in skincare, providing a deeper, more targeted approach to hydration. As skincare science continues to evolve, we can expect to see even more innovations that harness the full potential of hyaluronic acid in a way that respects and supports the skin’s natural structure.

When it comes to anti-aging, hydration, and overall skin health, multimolecular hyaluronic acid is a must-have ingredient. By delivering moisture at every layer of the skin, it ensures a comprehensive, lasting approach to skincare that can benefit all skin types and ages.
