COSRX: The Epitome of Korean Skincare


Whether you’ve used their products or not, COSRX is a brand you’ve definitely heard of if you’re even remotely interested in skincare. This Korean brand is not restricted to K-Beauty circles – it has broken into the mainstream skincare market and is purchased and admired by people all over the world. In addition to being affordable, COSRX products are not only easy to navigate, but also extremely effective.

COSRX: From Infancy to Making It Big

The Beginning

COSRX was established in 2013 as a skincare brand focused on ingredients. With COS standing for cosmetics, and RX for prescriptions, the brand started out with a simple aim: to provide solutions for skin problems. Using the slogan “Expecting Tomorrow”, COSRX sought to improve customers’ tomorrows by providing them with high-quality ingredients that would help irritated skin.

Concept & Marketing

With sensitive skin, skin-friendly ingredients, and the importance of texture in mind, COSRX began to provide solutions to customers’ problems.

COSRX didn’t just work tirelessly to perfect their formulas – everything down to the font in their logo is carefully thought out, from the thickness of the letters to whether they are aligned to the center. From brand colors to a doodled ambassador, meticulous crafting and attention to detail is what has set COSRX apart from other brands.

Brand Philosophy

COSRX has a very simple philosophy which has remained consistent throughout their existence – simple ingredients that result in great formulas. To make sure that their formulas are sensitive-skin friendly, COSRX ensures that products are dermatologist tested and hypoallergenic.

Brand Evolution

In 2015, COSRX released the Low pH Good Morning Gel Cleanser with feedback from customers, and in 2019, the brand presented a new version of itself – one that emphasized sincere solution-seeking in order to solve issues and provide relief to customers and their beauty needs.

The COSRX Formula: Why It Works

The popularity of COSRX in mainstream media has propelled it to new heights – with skincare influencers singing the brand’s praises, and the K-Beauty revolution spreading across the world, there is more demand than ever for COSRX products.

Not only has COSRX been forthcoming about the ingredients they use in their products, but they have also been very vocal about the ingredients they do not use. Since 2015, the brand has marketed itself as one that is completely transparent about ingredients used, and has even provided customers with an ingredient blacklist. With talc, mineral oils, formaldehydes, oxybenzone, and several other ingredients completely blacklisted by COSRX, as well as the brand’s clear status as cruelty-free, users know that they are investing their hard-earned money into products that align with their needs and values.

Top 10 COSRX Recommendations

While there are dozens of excellent products from COSRX, we have decided to focus on ten of our favorites. Some of them are old favorites while others are newer releases that make us love the brand even more.

The Best COSRX Products

COSRX AHA 7 Whitehead Power Liquid

With glycolic acid and apple fruit water, this treatment uses thorough exfoliation to eliminate whiteheads and dead skin, leaving your skin clean and hydrated. In addition to glycolic acid, this formulation uses niacinamide to fight acne as well as brighten the skin. Both powerful ingredients work toward evening out skin tone as well as skin texture. Sodium hyaluronate and panthenol add to niacinamide’s moisturizing effect, and make sure to keep your skin hydrated.

COSRX AHA/BHA Clarifying Treatment Toner

This spray toner uses a combination of betaine salicylate and glycolic acid to exfoliate the user’s skin, while using willow bark water, allantoin, and panthenol to ensure a strong skin barrier. In addition to exfoliation, this versatile product balances the skin’s pH level, while also soothing and deeply hydrating the skin.

COSRX Advanced Snail 96 Mucin Power Essence

The COSRX Snail Mucin line is well-known in the K-Beauty world, with the power essence being an international bestseller. This essence manages to prevent transepidermal water loss by using snail secretion filtrate to keep the skin extremely hydrated. This moisturizing essence is made with 96% snail mucin, which translates into the slightly tacky texture. However, with fast absorption, the feeling soon disappears, leaving behind a hydrated base ready for either makeup or sunscreen.

While all skin types can benefit from this, this is especially suitable for those with combination and oily skin types, since it has a gel texture and provides deep hydration without the need for oils. In addition to snail mucin, other ingredients of note are hyaluronic acid, arginine, betaine, panthenol, and allantoin.

COSRX Acne Pimple Master Patch

A product that everyone knows and loves is the COSRX pimple patch set, which consists of hydrocolloid patches that are used on active pimples to keep them hydrated and protected from bacteria. Often referred to as miracle workers, these patches often calm down irritated skin within hours of application.

COSRX Aloe Soothing Sun Cream SPF 50+ PA+++

Often confused for moisturizer, this sunscreen has a lightweight, silky texture, and absorbs into the skin extremely quickly. Loved by those with dry and sensitive skin types, this sunscreen brags soothing aloe leaf extract, dipotassium glycyrrhizate, glycerin, and butylene glycol which keep the skin hydrated all day long. In addition to its non-greasy texture, this sun cream is known for having no white cast and is a favorite among K-Beauty lovers.

COSRX Centella Blemish Cream

Beloved by oily and sensitive skin types, the COSRX centella cream primarily consists of its namesake centella asiatica lead water. However, it also includes centella asiatica extract, and other calming ingredients such as tea tree leaf oil, viola tricolor extract, and scutellaria baicalensis root extract. These, combined with cica, make this cream excellent for inflammation and blemishes.

Acne-fighting ingredients like zinc and tea tree oil also help combat inflammation and reduce the appearance of scars. These ingredients, alongside glycerin, butylene glycol, and betaine, make this an extremely hydrating cream that can be used as a spot treatment or as an overall moisturizer.

COSRX Galactomyces 95 Tone Balancing Essence

This clarifying and anti-aging essence is severely underrated and deserves more love from COSRX users. Its ingredient list is chockfull of intensely hydrating compounds and antioxidants that are sure to nourish and hydrate your skin, as well as slow down visible signs of aging such as wrinkles. The star ingredient, galactomyces ferment filtrate, is more than just a moisturizing agent – it has antioxidant effects, improves the skin’s protective moisture barrier by protecting it from environmental stressors, and both, prevents and treats acne. This miracle ingredient also controls sebum production and has anti-aging benefits. Other ingredients like betaine smoothen out the skin’s rough texture, reduce the appearance of wrinkles, and deeply hydrate and soothe the skin. These, combined with niacinamide, allantoin, adenosine, hyaluronic acid, and panthenol make this product amazing for all skin types and concerns.  

The Latest COSRX Products

This cooling gel cleanser is loved by many, and often hailed as one of COSRX’s best products. This versatile cleanser is suitable for all skin types and uses both exfoliating and hydrating ingredients.

This toner contains both AHAs and BHAs but is not irritating at all. In fact, it’s safe for daily use, making it great for all skin types. Not only does it exfoliate the skin, but it also includes Vitamin C, an ingredient that is anti-aging, collagen boosting, and reduces hyperpigmentation. While the chemical exfoliants in the toner make sure to clarify the skin, niacinamide serves to provide both anti-acne and brightening benefits.
