COSRX has established itself as a prominent player in Korean skincare (K-beauty), well-known for its effective yet gentle products. COSRX has achieved international success with popular ingredients like snail mucin and has become a reputable name in both the USA and Europe. By offering innovative solutions with proven results, COSRX has gained the trust of skincare enthusiasts worldwide.
Philosophy & Background
COSRX was founded in 2013 in South Korea by Jun Sang Hun, based on customer insights into skin problems he has gathered since 2002. The name COSRX is a combination of the words “cosmetics” and “RX” (as in prescription), symbolizing the brand's focus on customized solutions for skin needs. COSRX's philosophy is based on science-based, gentle, and natural skincare, where each product is developed with a few carefully selected and proven ingredients to maximize effectiveness and minimize irritation. COSRX's motto, “Expecting Tomorrow”, reflects the ambition to contribute to improved skin health over time with skin-friendly ingredients. COSRX places great importance on customer feedback and needs, and strives to offer skincare that combines gentleness with high performance – a feature that has made it particularly popular among people with sensitive skin. All products are manufactured in Korea and are cruelty-free, which means that no animal testing is conducted.
What makes COSRX unique?
One of COSRX's main strengths is its innovative ingredients and advanced technology that position the brand as a leader in K-beauty. COSRX is particularly known for its use of unique natural ingredients, such as snail secretion (snail mucin) and Centella Asiatica (“Cica”), which are used in high concentrations to effectively soothe, hydrate, and repair the skin deeply. This approach makes COSRX a pioneer, especially in the care of problematic skin and sensitive skin that requires gentle yet effective treatment.
Additionally, COSRX has a clear customer-focused and ingredient-driven development strategy. The products are formulated with short and carefully considered ingredient lists, free from unnecessary additives like fragrance or harsh chemicals, and instead rich in high-quality plant extracts and active substances. This leads to skincare that is gentle yet highly effective, making the products particularly suitable for strengthening the skin barrier and treating specific skin issues without causing irritation. COSRX was also an early player in special solutions like acne patches (hydrocolloid patches) and mild chemical exfoliations, innovations that today influence many other brands within K-beauty. The combination of scientific expertise and natural ingredients, as well as a focus on real results rather than just outer beauty, has contributed to COSRX maintaining a loyal global customer base.
Finally, affordability is a central part of COSRX's identity. COSRX offers clinically effective formulations at affordable prices, enabling a wide audience – from beginners to experienced skincare enthusiasts – to discover South Korean skincare without exceeding their budget. The unique combination of natural ingredients, skin-friendly formulations, and affordable prices makes COSRX a distinctive and appreciated brand in the market.
Popular products from COSRX
COSRX has several best-selling products. Here are some of their most popular options and what makes them unique.
COSRX Acne Pimple Master Patch
Acne Pimple Master Patch are thin and transparent acne patches made of hydrocolloid material that are applied directly to the pimple to effectively absorb impurities and speed up healing overnight. The patches protect the treated area from bacteria and touch, helping to reduce redness, prevent scarring, and speed up the shrinking of the pimple. They are suitable for all skin types affected by individual blemishes and are particularly well-suited for acne-prone skin, offering a quick and targeted treatment without drying out the surrounding skin.
COSRX Advanced Snail 96 Mucin Power Essence
A lightweight Essence (serum) containing a full 96% snail secretion filtrate, which provides intense hydration and nourishment to the skin. The snail mucin helps to repair the skin barrier, promote healing processes, and give the skin a natural glow. The formula is fragrance-free, mild, and absorbs quickly without stickiness, making it ideal even for sensitive skin that needs effective treatment without irritation. The result is plumper, softer skin with a more even skin tone. The essence is particularly suitable for dry, dehydrated, or mature skin that needs extra vitality and elasticity, but it is suitable for all skin types seeking more hydration and radiance in their skincare routine.
COSRX BHA Blackhead Power Liquid
BHA Blackhead Power Liquid is a chemical exfoliating toner/essence developed to effectively counteract blackheads and clogged pores. The product contains 4% BHA (betaine salicylate, a mild form of salicylic acid) and niacinamide, which together dissolve sebum in the pores, balance oil production, and remove dead skin cells through exfoliation. By cleansing the pores deeply, it helps to prevent pimples and blackheads and reduce marks from previous blemishes, improving the skin's texture and clarity. This exfoliant is particularly well-suited for oily and acne-prone skin with a tendency for enlarged pores or blackheads, but it can also be used by combination skin. For beginners, a cautious introduction (1–2 times a week) is recommended as the product is powerful, while experienced users of acids appreciate its effective yet gentle formula free from alcohol and parabens.
COSRX Low pH Good Morning Gel Cleanser
An iconic mild gel cleanser with a low pH (~5.5) that effectively Cleanses the skin without disrupting its natural balance. It removes sebum and impurities while maintaining the skin's moisture levels and protective barrier. With its slightly acidic pH value, adapted to the skin's own, and active ingredients like tea tree oil and BHA, it helps to keep pores clean and prevent acne in a gentle way. The cleanser is mild and leaves no tightness – instead, the skin feels fresh, hydrated, and comfortable after use. Suitable for all skin types as a daily cleanser, but is especially appreciated by those with oily or combination skin who desire a deep-cleansing yet gentle product for morning cleansing.
COSRX AHA/BHA Clarifying Treatment Toner
AHA/BHA Clarifying Treatment Toner is a daily, mildly exfoliating toner in spray form that combines natural sources of AHA and BHA (apple water and willow bark water) with 0.1% glycolic acid and 0.1% betaine salicylate. The toner is applied after cleansing and helps to refine skin texture, add radiance, and keep pores clean. With regular use, it gently exfoliates away dead skin cells, which counteracts dullness and helps to prevent both acne and blackheads. Thanks to the low acid concentration, this toner is especially suitable for people who are new to acids or have sensitive skin – it improves the skin's texture without the risk of severe irritation. The result is softer, smoother skin that is more receptive to subsequent serums and creams. The toner can be used daily and is suitable for all skin types, but it is important to use sunscreen during the day as the product contains exfoliating acids.
Skin Types and Conditions
One reason for COSRX's success is that their products are carefully tailored for different skin types and skin issues. COSRX focuses on offering target-specific solutions – whether you have acne, dry skin, sensitivity, or aging skin, there are products developed for your needs. COSRX is especially appreciated by people with problem skin (acne, redness, eczema), thanks to formulations that are so gentle they rarely cause irritation, while effective active ingredients address skin issues. Their acne series (AC Collection) contains, for example, soothing Centella Asiatica and anti-inflammatory ingredients that reduce redness and help heal blemishes without damaging the skin barrier. Products like BHA Blackhead Power Liquid and acne patches are specifically designed for oily, acne-prone skin, where salicylic acid and niacinamide help control excess sebum, keep pores clean, and prevent breakouts.
COSRX offers a wide range of products to care for dry and dehydrated skin. Their Hydrium series, which contains hyaluronic acid, and products in the Advanced Snail series with snail mucin are excellent options for providing deep hydration and strengthening the skin's protective barrier. The snail secretion is rich in allantoin and other repairing substances that promote recovery for damaged or sensitive skin, which particularly benefits skin prone to eczema. COSRX has a consistent focus on choosing ingredients that strengthen the skin barrier and soothe irritation, making the products particularly suitable for sensitive skin. The majority of their range is also free from perfume, essential oils, and drying alcohol to minimize the risk of negative reactions. At the same time, the products contain active, natural extracts such as propolis, green tea, and centella, which help reduce redness and provide nourishment.
For those who want to work with dull skin, pigmentation, or anti-aging, COSRX offers several effective options. Their Propolis line (Full Fit), containing black bee honey propolis extract, nourishes and adds radiance to tired skin. Products with vitamin C (such as Triple C Lightning Liquid) and niacinamide are designed to even out skin tone and reduce pigmentation. Recently, the brand has also introduced retinol serums (such as The Retinol 0.5 Oil) and higher concentrations of vitamin C, which complement anti-aging routines by targeting fine lines and increased skin firmness. COSRX:s products are designed to be easily combined according to needs – for example, a moisturizing routine in the morning for radiance and an active routine in the evening focusing on exfoliation or anti-aging. The goal is to offer “customized” skincare routines where a few key products effectively address individual skincare needs.
In short, COSRX has established itself as a leading brand in helping skin types such as acne-prone, dry, dehydrated, mature, and sensitive skin in a way that few other brands can match. Whether you are dealing with stubborn pimples and large pores or if your skin feels tight, red, and irritated, there is a COSRX product with natural ingredients and scientifically developed formulations designed to deliver results.
Create a routine with COSRX
Creating an effective skincare routine with COSRX is easy and smooth. Here is an example of a daily routine in four steps with some of COSRX's best-selling products.
Cleansing – Low pH Good Morning Gel Cleanser
Start the morning and end the evening with Low pH Good Morning Gel Cleanser, a mild gel that effectively removes dirt and excess oils without drying out the skin. With a low pH value (~5), it maintains the skin's natural barrier, making the skin feel clean without becoming tight. Apply a small amount to a damp face, gently massage, and rinse with lukewarm water. Tip: If you use a lot of makeup or SPF in the evening, double cleansing is recommended, where this gel is used as step two after an oil-based cleanser. In the morning, it is excellent as a fresh start for the skin.
Treatment/Essence – Advanced Snail 96 Mucin Power Essence
After cleansing, apply a few pumps of Advanced Snail 96 Mucin Power Essence to the face and neck. This light and nourishing Essence effectively hydrates and cares for the skin. The snail mucin serum is quickly absorbed and provides intense moisture that plumps the skin and gives a healthy glow. The nutrient-rich filtered snail secretion also supports the skin's repair process – ideal for those with red marks from acne or a weakened skin barrier. Pat the essence in with your fingertips to maximize absorption. The skin is left soft, supple, and deeply hydrated all day without a sticky feeling. (If you use specific serums – such as vitamin C in the morning or BHA exfoliation in the evening – these can be included in this 'treatment step' either before or after the snail extracts, depending on the product's properties. Snail Essence is compatible with most active ingredients thanks to its gentle and moisturizing formula.)
Hydration – Advanced Snail 92 All In One Cream
The next step is to lock in moisture with a high-quality emollient. Advanced Snail 92 All In One Cream is an all-in-one cream consisting of 92% snail secretion and has a light gel-cream texture that is quickly absorbed by the skin. The cream repairs and soothes irritated skin, especially after breakouts or stressed skin, thanks to the nourishing properties of snail mucin. At the same time, the skin is provided with nourishment and moisture, resulting in a plump and smooth feeling – without an oily film, as the formula is both oil-free and non-comedogenic. Apply an appropriate amount over the entire face as both day and night cream. For extra dry skin, two thin layers can be applied, while combination or oily skin often prefers a thin layer. The result is a balanced and naturally radiant skin, ready to face the day's challenges.
Protection – Sunscreen (SPF)
The final step in the morning routine is sunscreen. Apply a broad-spectrum sunscreen with at least SPF 30, such as COSRX Aloe Soothing Sun Cream SPF 50+, to preserve the skin's moisture and protect against harmful UV rays. This step is crucial: SPF protects the skin from sun damage that can lead to wrinkles, pigmentation changes, and a weakened skin barrier. COSRX Aloe Soothing Sun Cream is a popular choice thanks to its soothing aloe vera content, light consistency, and the fact that it doesn't leave a white cast. Apply a generous layer as the final step in your morning routine, even on cloudy days, to preserve the results of your skincare routine and prevent new damage. Note: In the evening, no sunscreen is needed. Instead, the focus can be on reparative steps, such as exfoliation or using a nourishing sleeping mask.
Tip: Customize the routine according to your skin's needs. COSRX products are designed following the concept "R.T.P – Ready (cleanse), Target (treat), Protect (moisturize and protect)". This means that with a cleanser, a serum/Essence, and a cream with SPF, you can create an effective and simple skincare routine. If you have specific skin concerns, you can complement with a 'target' serum, such as niacinamide to minimize visible pores or retinol in the evening for anti-aging. We recommend starting with a few products and introducing new ones gradually. gradually increases. COSRX mild formulations make it easy to adjust the routine without burdening the skin. In a short time, you can create a complete K-beauty routine tailored to your needs!
FAQ (Common questions about COSRX)

Yes, COSRX is completely cruelty-free – neither the ingredients nor the finished products are tested on animals. COSRX is certified according to Korea's strict regulations against animal testing, and all products are manufactured entirely without animal testing.
Are COSRX products vegan?
Partially. COSRX is cruelty-free but not entirely vegan, as some products contain ingredients of animal origin. For example, snail secretion is used in the Snail series, and beeswax and propolis in some formulations, which are not classified as vegan. However, many of their products are vegan, such as the Hyaluronic series and some Cica products. For those who only seek vegan skincare, it is recommended to carefully review the ingredient list for each product.
Do COSRX products contain perfume or other irritating substances?
Generally no. COSRX is known for its minimalist formulations without unnecessary additives. Most products are free from added perfume, artificial colorants, and strong preservatives such as parabens. Instead, COSRX uses natural extracts, such as tea tree and propolis, to provide fragrance and desired properties. For people with fragrance sensitivity or allergies, COSRX products are often a good option, but it's always important to review the ingredient list to ensure the product suits your needs. A few products may contain small amounts of essential oils or similar ingredients, but overall, COSRX focuses on a "less is more" concept.
Is COSRX suitable for sensitive skin?
Absolutely. COSRX is designed with a special focus on sensitive and problem-prone skin that requires gentle care. Many of the products are hypoallergenic and dermatologically tested to suit sensitive skin (for example, the Snail Mucin essence is tested not to cause irritation, even for sensitive skin). COSRX also avoids commonly found irritants like perfume, alcohol, and sulfates, which makes the products often well-tolerated by people with conditions such as rosacea or eczema. Although skin reactions can vary from person to person, COSRX generally has a good reputation for soothing rather than irritating sensitive skin.
Does COSRX work against acne and pimples?
Yes, COSRX is particularly appreciated by people with acne-prone skin. Thanks to active ingredients such as BHA (salicylic acid), AHA, tea tree, and centella, they offer several products that effectively target pimples, blackheads, and excess sebum. For example, BHA Blackhead Power Liquid is an excellent product for cleaning pores and preventing breakouts, while their AC Collection (enriched with centella) is developed to accelerate the healing of acne and reduce the risk of scarring. Their acne patches are also very useful for quickly reducing inflammation and protecting the skin. By combining a complete skincare routine – including cleansing, exfoliating, spot treatment, and moisturizing – with COSRX products, one can effectively keep pores clean and acne under control in a gentle and results-driven manner.
Are COSRX products expensive?
No, on the contrary. One of COSRX's main strengths is that they offer high quality at a reasonable price. Compared to many Western brands with similar active ingredients, COSRX is significantly more affordable. This makes it possible to create an effective skincare routine – from cleansing to serum and cream – without having to pay an overpriced amount. COSRX prioritizes ingredients over lavish packaging, which is beneficial for the consumer. In summary, COSRX offers excellent skincare at a competitive price.
