  • Nothing to note at this time

Formula type: Serum | Key ingredients: Sodium hyaluronate, glycerin, sea buckthorn water 

The CosRx Hyaluronic Acid Hydra Power Essence, which has a light, water-based texture,  combines sodium hyaluronate, a potent form of hyaluronic acid , with glycerin and sea buckthorn water, both of which are moisturizing. According to the brand, it’s also formulated to soothe irritation, soften the appearance of fine lines, and improve skin tone overall. It’s also non-comedogenic — meaning it won’t clog pores — and free of parabens, sulfates, fragrances and other common irritants, making it safe for sensitive skin, says CosRx.

The brand suggests gently patting or massaging a few pumps to your face and neck — a little goes a long way, in my experience. I apply mine after toner and before any heavier serums for max absorption, and follow it up with moisturizer.

Why I love the CosRX Hyaluronic Acid Hydra Power Essence

Trying different products comes with the shopping expert territory, but I always come back to the CosRx Hyaluronic Acid Hydra Power Essence for three reasons.

Long-lasting hydration

In my experience, hydrating products for oily skin aren’t the easiest to find and few actually bring balance to my skin — but this essence is an exception. Issues that I have during transitional seasons, like tightness from dry patches and general dullness, are usually fixed after one use, but over time (and with continued use, of course),  it also helps to even out my tone and texture, which gives my face a brighter complexion. 

The hydration I feel lasts through all of my gym, work and life activities. It may be a bit lightweight for people with very dry skin, but it can also be mixed with heavier-duty hydrators and even into moisturizers for an added boost if needed.

Fast-absorbing formula

I’m awful at managing time, so I have a deep appreciation for how quickly this essence absorbs into my skin (under a minute, to be exact), especially when I’m running late to the train. Even when I don’t wait for it to fully absorb — usually because I’m too tired or behind schedule –the essence plays nice with my other products and doesn’t leave residue behind.

Lightweight, non-greasy finish

Every time I apply this essence, I look as though I just got a facial (for a fraction of the price, might I add). Hyaluronic acid serums are usually too thick for my liking, but CosRX’s essence is the most lightweight hydrator I’ve ever tried. Plus, the finish is dewy, not greasy — a dream come true for anyone with oily skin.
