Brand Overview

COSRX’s Triple C Lightning Liquid is a great vitamin C serum that can help improve skin’s radiance and tone.

This lightweight, serum-like fluid contains an impressive 20.5% vitamin C. That concentration puts Triple C firmly in the range of being able to make a marked difference in skin’s tone and discolorations. The black glass bottle with a dropper ensures the delicate ingredients will stay safe from light and air exposure during use.

As for the “Triple C” in the product’s name, we suspect it refers to the fact that the brand’s name is COSRX, and that this is a collaboration with Korean-American esthetician Charlotte Cho, who is considered one of the leaders in bringing K-Beauty to Western audiences (thanks to her being one of Soko Glam’s co-founders).

The fragrance-free serum is lightweight, and absorbs quickly into skin, so it works well either over or under other skin care products and is suitable for all skin types. In addition to vitamin C, there’s also antioxidant chokeberry and sicklepod extract, along with soothing licorice extract and allantoin, and skin-plumping sodium hyaluronate. Overall, Triple C Lightning Liquid is one of COSRX’s better products!

Pros:
  • Contains 20.5% vitamin C, which can significantly improve sun-damaged skin.
  • Includes antioxidant plant-based extracts and skin-soothing ingredients.
  • Packaged to keep its light- and air-sensitive ingredients stable.
  • Fragrance free.
Cons:
  • None.
Jar Packaging: No
Tested on animals: No

An exclusive collaboration between popular Korean acne brand COSRX and Charlotte Cho, the Triple C Lightning Liquid is a powerful vitamin C serum. Launched in 2017, Triple C sold out within four hours of launching, and has since become a cult favorite!

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.
