Brand Overview

Low pH First Cleansing Milk Gel feels great on skin and comes close to being great, but falls just short because of a couple of missteps.

This cleanser comes in squeeze tube. It has a light lotion texture that’s best for those with normal to dry skin. It feels soothing and does a good job removing dirt, oil, and makeup (though not longwearing or waterproof formulas, but COSRX doesn’t claim it can, either).

The cleansing action comes from gentle cleansing agents plus olive and castor oils. This blend won’t leave skin feeling dry or tight after rinsing, yet rinses cleanly, leaving skin feeling soft and conditioned.

While that’s good, this cleanser contains bergamot oil and witch hazel extract, which put skin at risk for irritation. Though this is a rinse-off product, the risk is still there (to say nothing of the potential to irritate eyes while you’re cleansing). We should point out however that Low pH First Cleansing Milk Gel smells far less potent than its sister product, Low pH Good Morning Gel Cleanser, which is why this has a higher rating.

That foible aside, this is still a very good cleanser that’s effective and has great aesthetics.

*Note: this cleanser, as claimed, has a low pH (5.64 to be specific). That’s good news since skin has a naturally acidic pH between 4 and 6, but most skin care products are within that range. The majority of products with a high pH are bar soaps, so this cleanser isn’t revolutionary in that sense.

Pros:
  • Light lotion texture feels soothing to normal to dry skin.
  • Does a good job removing dirt, oil, and non-waterproof makeup.
  • Rinses cleanly without leaving skin feeling dry or tight.
Cons:
  • Includes bergamot oil and and witch hazel extract, which put skin at risk for irritation.
  • The pH claims are far from unique to this cleanser.

Irritating Ingredients: We cannot stress this enough: Sensitizing, harsh, abrasive, and/or fragrant ingredients are bad for all skin types. Daily application of skincare products that contain these irritating ingredients is a major way we unwittingly do our skin a disservice!

Irritating ingredients are a problem because they can lead to visible problems, such as redness, rough skin, dull skin, dryness, increased oil production, and clogged pores, and they contribute to making signs of aging worse.

Switching to non-irritating, gentle skincare products can make all the difference in the world. Non-irritating products are those packed with beneficial ingredients that also replenish and soothe skin, without any volatile ingredients, such as those present in fragrance ingredients, whether natural or synthetic.

A surprising fact: Research has demonstrated that you do not need to see or feel the effects of irritants on your skin for your skin to be suffering, and visible damage may not become apparent for a long time. Don’t get lulled into thinking that if you don’t see or feel signs of irritation, everything is OK.

Generally, it’s best to eliminate, or minimize as much as possible, your exposure to ingredients that are known to irritate skin. There are many completely non-irritating products that contain effective ingredients, so there’s no reason to put your skin at risk with products that include ingredients research has shown can be a problem.

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.
