Do you put Polyglutamic Acid Serum before or after moisturizer?

When it comes to skincare, the order in which you apply your products can make a big difference in their effectiveness. One common question that arises is whether to put Polyglutamic Acid Serum before or after moisturizer. Let's delve into the science behind it.

What is Polyglutamic Acid Serum?

Polyglutamic Acid is a powerful humectant that can hold up to four times more moisture than hyaluronic acid. It helps to hydrate and plump the skin, making it look more youthful and radiant.  So in a skincare routine, correctly using Polyglutamic Acid (PGA) serum is crucial. To maximize the benefits of PGA serum, it's important to understand the order of application and the reasons behind it.



Cleansing the Skin

First, use a gentle cleanser to wash your face. This step effectively removes dirt, oil, and makeup residue from the skin's surface, laying the foundation for the subsequent skincare steps. Cleansing ensures your skin is in a clean state, allowing better absorption of the following skincare products.

Applying Toner

After cleansing, apply toner to further clean the skin while replenishing moisture and restoring the skin's pH balance. Toner also helps to open the skin’s absorption channels, making it easier for the following products to penetrate the skin.


Using PGA serum

Next comes the key step: applying PGA serum. Take an appropriate amount of PGA serum and gently pat it onto your face and neck. PGA serum is a powerful humectant with a molecular structure that can absorb and retain a significant amount of moisture. Studies show that PGA's moisturizing effect is up to four times higher than that of Hyaluronic Acid. It forms a protective layer on the skin’s surface, preventing moisture loss while enhancing skin hydration. PGA serum's small molecules are easily absorbed by the skin, penetrating deep to provide intense hydration. This makes it an essential step in the skincare routine, laying the foundation for subsequent moisturizing products. ANAIRUI'S Polyglutamic Acid serum combined with hyaluronic acid can provide a synergistic effect, maximizing hydration and helping to maintain the skin's moisture barrier. Regular use gives you a softer, smoother, and more supple skin.


Applying Moisturizer

Once the PGA serum is fully absorbed, the next step is to apply moisturizer. The primary function of the moisturizer is to lock in the moisture and nutrients from the previous skincare steps, providing long-lasting hydration and nourishment. The moisturizer forms a protective barrier on the skin’s surface, preventing moisture loss and further sealing in the hydration and nutrients provided by the PGA serum



Some people may ask why it is in this order. Serum molecules are typically smaller and more easily absorbed by the skin compared to moisturizers. If you apply moisturizer first, it may create a barrier that hinders the serum's absorption. By using PGA serum first, you ensure its active ingredients penetrate the skin effectively, providing deep hydration and preparing the skin for the moisturizer's sealing effect. This order maximizes the efficacy of each product, ensuring the skin receives the most comprehensive nourishment and hydration.

In a daily skincare routine, Polyglutamic Acid Serum should be used after cleansing and toning but before applying moisturizer. This order of application not only ensures the deep moisturizing effect of PGA serum but also enhances the moisture-locking function of the moisturizer. Following the proper steps allows your skin to appear healthier, smoother, and more vibrant. By adhering to the correct usage methods, you can significantly improve the overall effectiveness of your skincare products, leading to better skin texture and appearance.
