Brand Overview

COSRX’S Hydrium Watery Toner is exactly that – a fluid, toning solution that soothes skin – though we wish it were a little more potent.

Packaged in a lightly frosted bottle with a flip-top cap, this toner’s watery texture works for all skin types. It feels remarkably light(essentially, like splashing water on your face) and absorbs quickly to leave skin feeling lightly hydrated and refreshed. Its texture works well for all skin types, plus layers nicely both over and under other skin care products.

What you see is what you get here; COSRX advertises this as a hyaluronic acid and panthenol toner and that’s exactly what this entails. This contains five different forms of hyaluronic acid + panthenol, all of which serve to boost hydration as this claims. There’s also some soothing allantoin to help calm skin.

Other than that, there isn’t much else present – but, again, COSRX doesn’t make any grandiose claims about this product other than to say that it contains a lot of hyaluronic acid, which it does.

One note about the packaging: because this doesn’t contain antioxidant ingredients, it does not need to be stored out of light, even though it is only lightly frosted.

Overall, this fragrance-free toner is a good option for hydration that skips out on irritants that plague many other toners.

  • Water-light texture is suitable for all skin types.
  • Leaves skin feeling hydrated and refreshed.
  • Contains five forms of hyaluronic acid + conditioning panthenol.
  • Fragrance free.
  • Formula would be more impressive with additional beneficial ingredients.

COSRX is one of a growing number of Korean beauty brands – a category known by many simply as K Beauty – that’s gaining a foothold in the Western cosmetics world. COSRX got its start in 2014, though it’s essentially an offspring of older “sister” brands, including C20 and Gatzmen, which have longer-standing histories in the Korean market. As the story goes, COSRX came about after the parent company compiled a decade’s worth of research based on customer data and beauty consumer research.

The brand name, as you might have guessed, is a mash-up of “cosmetics” and “RX” (for prescription), and illustrates COSRX’s overall philosophy. Whereas some other K-beauty brands are known for whimsical packaging and brightly-colored products, CosRX’s focus is minimalistic packaging and products designed to target specific skin care concerns, each highlighted by active ingredients.

To that end, the brand is largely successful. Most of the packaging is designed to protect light- and air-sensitive ingredients, though there are some jars in the mix. The formulas focus on active ingredients such as alpha hydroxy acids, hyaluronic acid, and beta hydroxy acid (though it should be noted, COSRX uses BHA derivatives, since salicylic acid’s use is restricted in Korea).

Most of the exfoliants are formulated at the optimal pH for exfoliation, which is between 3 and 4, and are fragrance free. Unfortunately there are some formulas that include natural ingredients that can potentially sensitize skin, including pine and cedar extracts, and anise fruit extract – proof once again that natural isn’t always better! Some products also contain drying alcohol, which is interesting since other products are specifically advertised as being “alcohol-free.”

Overall, this line is worth considering, especially if you prefer a more targeted approach to skin care that focuses on science rather than trends.
