Brand Overview

Pros:
  • Lightweight texture is suitable for all skin types.
  • Contains three forms of plumping and hydrating hyaluronic acid.
  • Packaged to protect its light- and air-sensitive ingredients.
  • Fragrance free.
Cons:
  • Slight foaming effect upon initial application.
  • Formula would be more impressive with additional beneficial ingredients.

COSRX’S Hydrium Triple Hyaluronic Moisture Ampoule is a good serum that plumps skin, but with a bit more “oomph” it would truly rank among the best of the best.

First, a quick note on ampoules; in general, they refer to vials used to contain solutions, but in the world of K-Beauty (Korean skin care), ampoules are concentrated formulas meant to work like serums.

In this case, this product – which comes in an opaque bottle with a dropper dispenser – has a serum texture that is lightweight, making it suitable for all skin types.

A curiosity is the slight “foaming” effect when it first comes in contact with skin. Although surprising, it disappears after a minute or two, absorbing completely without any sticky residue.

As the name implies, this contains skin-plumping and hydrating hyaluronic acid (in three forms), as well as conditioning panthenol to smooth skin. There’s a smattering of polyhydroxy acid gluconolactone, which, in greater concentrations can have exfoliating properties, but here it just further boosts hydration.

It’s a simple formula and it would be more impressive with a greater amount of beneficial ingredients (such as antioxidants) – still, this is a product that can do what it says, and skips irritating fragrance as well.

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.
