Dehydration is one of the most common skincare concerns, and it doesn't discriminate—whether your skin is dry, oily, or somewhere in between, it can still get dehydrated. When your skin lacks water, it tends to look dull, feel tight, and those fine lines become a little too noticeable. Without enough hydration, your skin’s barrier also gets weaker, making it more prone to sensitivity, environmental stressors, and even breakouts. The good news? Achieving proper hydration is totally doable, especially when you’ve got powerhouse ingredients like hypochlorous acid (HOCl) and polyglutamic acid (PGA) in your skincare arsenal. Together, they work like magic to give you smoother, plumper, and healthier skin.

What Exactly Is Polyglutamic Acid?
Polyglutamic acid is a hydrating superstar—it’s a water-soluble peptide that can hold up to 5,000 times its weight in water. Yeah, you read that right. That makes it even more powerful than hyaluronic acid when it comes to hydration. You’ll often find it in serums and creams designed to boost hydration, improve skin elasticity, and smooth out texture. What sets polyglutamic acid apart is its ability to form a protective film on your skin, which helps lock in moisture for much longer.
Made from fermented soybeans, polyglutamic acid works by creating a moisture-locking layer on the skin’s surface. It also prevents the breakdown of hyaluronic acid, so your skin can retain its natural moisture more efficiently.
Why You Need Hypochlorous Acid and Polyglutamic Acid Together
Hydration: Polyglutamic acid draws moisture. Hypochlorous acid does the heavy lifting by reducing any inflammation or irritation. The combo is perfect if your skin is both dry and sensitive, ensuring it stays hydrated and calm.
Smoother Skin Texture: Not only does polyglutamic acid plump up your skin by boosting hydration levels, but hypochlorous acid also steps in to calm inflammation and keep your skin barrier strong. The result? Skin that looks and feels smoother.
Locks in Long-Lasting Moisture: Polyglutamic acid forms a protective layer over your skin, locking in hydration for hours. Meanwhile, hypochlorous acid helps ensure your skin barrier stays intact and irritation-free. Together, they provide long-lasting hydration that can benefit anyone, especially those with dehydrated or dry skin.
How to Layer Hypochlorous Acid and Polyglutamic Acid in Your Routine
Cleanse: Start with a gentle, hydrating cleanser that doesn’t strip your skin.
Apply Hypochlorous Acid: After cleansing, spritz or mist hypochlorous acid to soothe and prep your skin for hydration.
Apply Polyglutamic Acid: Once the hypochlorous acid has fully dry, follow up with a polyglutamic acid serum or moisturizer to lock in moisture.
Moisturize: If you used a serum, make sure to top it off with a rich moisturizer to keep your skin hydrated and protected.
Sunscreen: Always use suncreen when you’re stepping outside. It helps prevent moisture loss and shields your skin from harmful UV rays.
