From dermatologists to beauty editors, Hyaluronic Acid (HA) has been dubbed the secret to hydrated skin. Like any natural Humectant, they help to attract water from the deeper levels of the skin to the surface and keeps the deeper layers well hydrated too. Hydration is key in anti-ageing skincare products, keeping your skin firmer and tighter, reducing fine lines and wrinkles.

Hyaluronic Acid is great, right? But these days, ‘great’ just isn’t good enough. Meet Polyglutamic Acid (PGA)— it’s like Hyaluronic Acid, except it is better…, 10 times better, in fact. This naturally occurring biopolymer is a powerful natural humectant that has the ability to lock in 10 times more moisture than hyaluronic acid, and aids in the skin’s exfoliation process. It also helps to promote the skin’s elasticity (collagen production) and minimizes pigmentation.

How is it different from Hyaluronic Acid?

What makes it different from HA? The natural molecule present in HA can sometimes fall in levels (perhaps due to dryer climates) and thus needs replenishing. Well, not for Polyglutamic Acid. It forms a film on the skin’s surface, preventing water from evaporating altogether. It’s kind of a 2-in-1: it not only hydrates but stimulates moisturizing processes.

Inkey List’s Polyglutamic Acid is a lightweight face serum that holds up to four times more moisture. Use it at night and in the morning for optimal effect, before your moisturizer. In fact, you can even use this as a hydrating makeup primer!


That said, don’t kick yourself over the stash of HAs you’ve accumulated over the years. Hyaluronic acid makes for a good booster for the next product that follows, allowing it to penetrate deeper. Using Polyglutamic acid after HA, it enhances the hydration by decreasing HA breakdown. This combination seals the top layer of skin, minimizing the amount of water that leaves our skin.

Inkey List retails at SEPHORA for SGD$22.
