Hyaluronic Acid vs Glycerin, Ceramides, & PGA: Which Hydrator Wins?

Among the most popular hydrators on the market today is hyaluronic acid. But how do they compare? Which one is the best for your skin? Or are there other hydrators that might be even better? In this article, we'll explore the unique qualities of hyaluronic acid, glycerin, and other well-known hydrators like ceramides and polyglutamic acid (PGA).

What is Hyaluronic Acid?

First, let’s talk about hyaluronic acid, a name that sounds all serious and science-y, but really hyaluronic acid is a natural substance found in the body, primarily in the skin, eyes, and joints. Hyaluronic acid is naturally produced by the body and can hold up to 1,000 times its weight in water. As a result, hyaluronic acid is often found in moisturizers, serums, and masks to help boost hydration levels and provide plump, youthful skin.

Unlike oils or emulsifiers, hyaluronic acid has a lightweight, gel-like consistency that works well for all skin types, even those with oily or acne-prone skin.
Hyaluronic acid is also known for its anti-aging properties, as it helps to reduce the appearance of fine lines and wrinkles by making the skin appear more plump and supple.

However, there are a few things to keep in mind when using hyaluronic acid. While it’s great at drawing moisture to the skin, it can sometimes feel a little dry if not paired with a good moisturizer. It’s also important to use it on damp skin, as hyaluronic acid works best when it has access to moisture.

When used with other ingredients like AHAs or retinols, it may cause some irritation or stinging, so it's best to apply it carefully, like how you wouldn’t mix your coffee with an energy drink—just doesn't mix well.

What About Glycerin?

Like hyaluronic acid, glycerin is another humectant that helps draw water into the skin. However, there are key differences between these hydrators. Made from smaller molecules, glycerin penetrates deeper into the skin, offering hydration right where it’s needed. This makes glycerin an excellent option for targeting hydration in the deeper layers of the skin.

On the flip side, while glycerin works wonders for dry skin, it can sometimes feel heavy on oily or acne-prone skin. This is because glycerin can attract moisture not only from the air but also from deeper layers of the skin, which may lead to clogged pores and breakouts for certain skin types.

Hyaluronic Acid vs. Glycerin – Which is Better?

So, which one is better: hyaluronic acid or glycerin? Babe, it is all based on what your skin needs. Both ingredients offer excellent hydration benefits, but they work slightly differently.

  • Hyaluronic acid is ideal for those looking for a lightweight, surface-level hydration boost. It’s perfect for individuals who want to enhance their skin’s moisture without feeling weighed down. It’s especially effective when paired with other moisturizing products to lock in hydration.
  • Glycerin on the other hand, provides deeper hydration, making it a good option for individuals with dry or dehydrated skin. It’s particularly beneficial for those who want to treat dryness that goes beyond the surface and targets the skin’s deeper layers.

For sensitive skin, glycerin might be the gentler option, as it’s less likely to cause irritation compared to hyaluronic acid when used with strong active ingredients. However, for those with oily or acne-prone skin, hyaluronic acid may be the better choice, as it’s less likely to clog pores.

Hyaluronic acid vs Ceramides and Polyglutamic Acid (PGA)

While hyaluronic acid is one of the most commonly used hydrators in skincare, there are other options to consider depending on your skin’s needs.

Ceramides

Ceramides are fats that are naturally in the skin. They play a crucial role in maintaining the skin’s protective barrier, which helps prevent moisture loss and protects against harmful environmental factors. Unlike hyaluronic acid, which primarily focus on hydrating the skin, ceramides help strengthen the skin's barrier to lock in moisture more effectively.

Ceramides are often found in products designed to treat eczema, psoriasis, and other skin conditions that compromise the skin’s protective layer.

Polyglutamic Acid (PGA)

Another up-and-coming hydrating ingredient is polyglutamic acid (PGA). Like hyaluronic acid, PGA is a humectant that draws moisture into the skin, but it has a few extra benefits. PGA can hold four times more water than hyaluronic acid, making it an even more powerful hydrator. It also enhances the skin’s ability to absorb other active ingredients, which can boost the overall effectiveness of your skincare routine.

Besides its hydrating properties, PGA is also known for improving skin elasticity, making it a popular choice for anti-aging products.

How to Use Hyaluronic Acid and Other Hydrators in Your Skincare Routine

No matter which hydrator you choose, it's essential to apply it correctly to get the most benefit. Here are some practical tips for incorporating hyaluronic acid, and other hydrators into your daily routine:

  • Apply on Damp Skin: To get the most out of hyaluronic acid, always apply it to damp skin. This will allow it to draw moisture from the environment and lock it into your skin more effectively.
  • Pair with a Moisturizer: Since hyaluronic acid and glycerin are both humectants, they can attract moisture from the air and deeper layers of the skin. To prevent moisture loss, always follow up with a good moisturizer that will seal in hydration. Petroleum jelly is also a good choice.
  • Layer Wisely: If you're using products with hyaluronic acid, glycerin, or PGA, consider layering them in the right order. Start with lighter, water-based products, followed by thicker creams and oils to lock in moisture.
  • Patch Test New Ingredients: If you have sensitive skin or are trying a new product, always patch test before applying it to your entire face. This will help you avoid potential irritation.
  • Consult a Dermatologist: For personalized advice, it's always a good idea to consult a dermatologist, especially if you're dealing with specific skin concerns like acne or rosacea.

Which One is the Right Hydrator for Your Skin

Hyaluronic acid and other hydrators are good options for hydration, but they serve slightly different purposes. Hyaluronic acid is ideal for surface-level hydration and works well for all skin types, while glycerin is better for deeper hydration, making it great for dry or dehydrated skin.

If you’re looking for something with additional benefits, ingredients like ceramides and polyglutamic acid can offer extra moisture while strengthening the skin’s barrier or enhancing the absorption of other active ingredients.
