3 Ways to Boost Hydration with Multi-Quench Polyglutamic Acid Serum

Dehydrated skin can feel tight, look dull, and exaggerate fine lines. While drinking water helps, your skincare routine plays a bigger role in locking in moisture. Enter polyglutamic acid (PGA), a powerhouse humectant that holds up to 4,000 times its weight in water—outperforming even hyaluronic acid. Prequel’s Multi-Quench Polyglutamic Acid Serum is designed to deliver deep, lasting hydration without stickiness. But how do you get the most out of it? Here are three expert-backed ways to boost hydration with this serum.

Whether you’re new to PGA or looking to level up your routine, these tips will help your skin stay plump, smooth, and radiant all day. Plus, we’ll show you how to pair the serum with other Prequel favorites for even better results.

1. Layer It Under a Moisturizer for Maximum Lock-In

The most straightforward way to boost hydration is to apply the Multi-Quench Polyglutamic Acid Serum onto damp skin, then seal it with a rich moisturizer. PGA draws moisture from the environment and deeper layers of the skin, but it needs an occlusive layer to prevent water loss. After cleansing and toning, apply 2–3 drops of the serum to your face and neck while skin is still slightly damp. Wait 30 seconds for it to absorb, then follow with a cream like Barrier Therapy Skin Protectant Cream For Face & Body. This combination creates a moisture reservoir that keeps skin hydrated for hours.

For an even more intense boost, try the “sandwich” method: apply a thin layer of moisturizer first, then the serum, then another layer of moisturizer. This technique is especially helpful for dry or compromised skin barriers. The Barrier Therapy Rich Skin Protectant Cream For Face & Body works beautifully here, as it contains ceramides and shea butter to reinforce the skin’s natural barrier.

• Apply serum on damp skin for better absorption.
• Wait 30 seconds before layering moisturizer.
• Use the sandwich method for extra dry areas.

2. Boost Your Mist Routine with a Serum-Mist Combo

Hydrating mists are a quick pick-me-up, but they can sometimes evaporate and leave skin drier. The trick is to pair a mist with a humectant serum. Start by spritzing the Multi-Quench Mist over your face—it’s formulated with polyglutamic acid and glycerin for instant hydration. While the mist is still wet, press 2–3 drops of the Multi-Quench Polyglutamic Acid Serum into your skin. The mist provides a water layer that the serum can latch onto, amplifying its hydrating power.

This duo is perfect for midday refreshes or as a prep step before makeup. Keep the Travel Size Hypochlorous Acid Spray handy for a gentle, antibacterial mist that also calms redness, but for pure hydration, the Multi-Quench Mist and serum combo is unbeatable. You can even mix a drop of the serum into your mist bottle for an on-the-go hydration boost.

• Spray mist first, then apply serum while skin is damp.
• Use Multi-Quench Mist for a complementary PGA boost.
• Mix a drop of serum into your mist for travel.

3. Use It as a Targeted Treatment for Dry Patches

Sometimes your whole face doesn’t need extra hydration—just those stubborn dry patches around the nose, cheeks, or chin. The Multi-Quench Polyglutamic Acid Serum works wonderfully as a spot treatment. After your regular routine, apply an extra drop to dry areas and gently pat it in. Follow with a thicker balm or cream to seal the area. For very dry or cracked skin, consider layering the serum under the Moisturizing Gel Socks For Dry, Cracked Feet on your hands or feet overnight.

For facial dry patches, the Barrier Therapy Skin Protectant Cream For Face & Body is an ideal partner. Its lightweight yet protective formula won’t clog pores, making it suitable for daily use. This targeted approach ensures you’re not over-hydrating oily zones while giving parched areas the intense moisture they crave.

• Apply extra serum to dry patches before moisturizer.
• Pair with Barrier Therapy Cream for spot treatment.
• Use on hands or feet with gel socks for overnight repair.

Boosting hydration doesn’t have to be complicated. By layering the Multi-Quench Polyglutamic Acid Serum correctly, pairing it with a hydrating mist, or using it as a targeted treatment, you can achieve a dewy, plump complexion.
