Hyaluronic Acid has long reigned supreme for deep moisturization. But many are now hyping Polyglutamic Acid. What’s the deal, and which is really better?
The skincare world is buzzing with talk of two powerful ingredients: Hyaluronic Acid (HA) and Polyglutamic Acid (PGA). Both are celebrated for their hydrating properties, but which one truly delivers the results you’re looking for? If you’re feeling torn between these two options, this article will guide you through their strengths, differences, and why we believe HA takes the crown as the ultimate hydration hero.
What Makes Hyaluronic Acid (HA) So Effective?

Hyaluronic Acid is a naturally occurring molecule in your skin that plays a critical role in maintaining moisture, elasticity, and that youthful glow. Here’s why it’s a favorite in skincare:
- Deep Hydration: HA penetrates multiple layers of the skin, providing moisture where it’s needed most.
- Plumping Power: With the ability to hold up to 1,000 times its weight in water, HA fills in fine lines and wrinkles, making skin appear smoother and firmer.
- Skin Repair: HA supports your skin’s natural barrier, reducing redness and irritation while locking in long-term hydration.
What About Polyglutamic Acid (PGA)?
Polyglutamic Acid has recently gained attention as a hydration powerhouse. Derived from fermented soybeans, it works differently than HA, offering unique benefits:
- Moisture Lock: PGA forms a barrier on the skin’s surface to prevent water loss, keeping skin hydrated for longer.
- Amplifies Other Ingredients: PGA enhances the absorption of other active ingredients in your skincare routine.
- Smoother Surface: By locking in hydration, PGA helps the skin look smoother and more radiant.

While PGA excels at surface hydration, it doesn’t penetrate as deeply as HA. This makes it better suited as a complementary ingredient rather than a standalone solution.
HA vs. PGA: The Ultimate Comparison
Here’s a side-by-side look at how these two ingredients stack up:
Feature | Hyaluronic Acid | Polyglutamic Acid |
---|---|---|
Hydration Depth | Penetrates deep into the skin | Locks moisture on the surface |
Moisture Retention | Holds 1,000x its weight in water | Holds 4,000x its weight in water |
Barrier Support | Repairs the skin barrier | Enhances surface hydration |
Boosting Ingredients | Improves ingredient absorption moderately | Amplifies ingredient absorption significantly |
The Secret to Truly Effective HA Treatments
Not all HA products are created equal. The best formulas contain 3 molecular densities of HA to deliver hydration on every level:
- High Molecular Weight HA: Sits on the skin’s surface to smooth and hydrate instantly.
- Medium Molecular Weight HA: Penetrates deeper to boost elasticity and plumpness.
- Low Molecular Weight HA: Reaches the deepest layers to provide lasting hydration and stimulate collagen production.

When these three densities work together, your skin experiences hydration from surface to core, ensuring both immediate and long-term results.
TRUE Serums HA Formula: The Game-Changer
One product that masters the science of Hyaluronic Acid is TRUE Serums HA Formula. This advanced serum combines all three molecular densities of HA into one formula. Here’s what makes it exceptional:
- Instant Results: High molecular weight HA smooths the skin immediately, creating a dewy, hydrated finish.
- Long-Term Transformation: Medium and low molecular weight HAs work to improve elasticity, firmness, and hydration at deeper levels over time.
- Enhanced Formula: TRUE Serums also includes peptides to amplify hydration and skin renewal.
One user, Carol, 65, shared her story:
“TRUE Serums HA Formula has completely transformed my skin. My fine lines are softer, and my skin looks and feels healthier. It’s my new skincare must-have!”
5 Things to Watch Out For When Using HA or PGA Products

- Patch Test First: Always test a small amount of any new product on a discreet area of your skin to ensure no allergic reactions or sensitivity before full application.
- Layering Smartly: If you’re using both HA and PGA, apply HA first to hydrate deeply, then follow with PGA to lock in moisture. Improper layering could reduce effectiveness.
- Avoid Harsh Ingredients: Pairing HA or PGA with overly harsh exfoliants or drying agents can counteract their hydrating benefits and lead to irritation.
- Choose the Right Formulation: Not all products are created equal. Look for HA formulas that include three molecular densities for the best results.
- Watch for Overuse: While HA and PGA are generally safe, over-applying products can lead to a sticky residue or clogged pores. Stick to the recommended amounts for optimal results.
The Verdict: Why HA Wins
While Polyglutamic Acid has its place as a surface hydrator and booster, it can’t match the transformative power of Hyaluronic Acid. HA works at every level of your skin, delivering immediate hydration, long-term rejuvenation, and improved elasticity. With its versatility and proven results, HA is the cornerstone of any effective skincare routine.
Moral of the Story
When it comes to hydration, Hyaluronic Acid is the gold standard. Its ability to penetrate deeply and work on multiple levels makes it superior to other ingredients like PGA. For the best results, choose a product like TRUE Serums HA Formula, which incorporates all three molecular densities of HA for comprehensive hydration and anti-aging benefits.
