Expert Tip for Polyglutamic Acid

"Hydration is the foundation of a healthy, glowing complexion. After cleansing and applying your serum, layer on a polyglutamic acid product to lock in moisture and boost your skin's natural hydration levels. Known for holding four times more moisture than hyaluronic acid, polyglutamic acid helps smooth fine lines, plump the skin and create the perfect base for your moisturiser or SPF."

Frequently Asked Questions

What is polyglutamic acid in skincare?

Polyglutamic acid is a powerful humectant derived from fermented soybeans that helps lock in moisture, improve skin texture and boost elasticity.

Is polyglutamic acid better than hyaluronic acid?

While both are excellent hydrators, polyglutamic acid can hold even more moisture than hyaluronic acid and forms a breathable film on the skin to prevent water loss, making them ideal to use together.

Yes, polyglutamic acid is gentle enough for daily use and works well in both morning and evening skincare routines.

Which skin types benefit most from polyglutamic acid?

All skin types can benefit, but it's especially effective for dry, dehydrated or dull skin that needs an extra hydration boost.

Can I layer polyglutamic acid with other active ingredients?

Absolutely. Polyglutamic acid pairs well with ingredients like vitamin C, retinol and niacinamide, enhancing hydration without causing irritation.

What are the best polyglutamic acid products for dry skin?

Look for polyglutamic acid serums or moisturisers designed to boost hydration and improve skin barrier function, these are ideal for replenishing moisture in dry skin.

Is polyglutamic acid safe for sensitive skin?

Yes, polyglutamic acid is non-irritating and suitable for sensitive skin, offering deep hydration without the risk of inflammation.

How do I add polyglutamic acid to my skincare routine?
