COSRX

COSRX is one of the most acclaimed brands in Korean skincare – known for its minimalist yet powerful formulations. With a clear focus on active ingredients, scientifically proven methods, and a strong emphasis on results, COSRX has become a favorite among both skincare enthusiasts and beginners worldwide.

What is COSRX?

COSRX is a South Korean skincare brand founded in 2014 with a clear vision: to offer effective skincare based on science and real needs. The name COSRX is a combination of the words "cosmetics" and "prescription" (RX), reflecting the company's philosophy of combining cosmetic innovation with medical precision.

Unlike many other brands in the beauty industry, COSRX has always chosen to let the content speak for itself. Instead of investing in flashy packaging, they focus on active ingredients with documented effects. The result? Skincare products that truly work – whether you're struggling with acne, dryness, or sensitivity.

COSRX philosophy – Minimalism and maximum effect

COSRX is known for its uncompromising philosophy: skincare should be effective, gentle, and scientifically backed. By combining proven ingredients with simple formulations, COSRX creates products that deliver visible results without irritating the skin. Here are some of the cornerstones of their approach.

Scientifically proven ingredients

COSRX was early in highlighting powerful active ingredients in their products. Among their most used ingredients are:

• AHA (glycolic acid) – Gently exfoliates, improves skin texture, and helps reduce pigmentation spots.
  
• BHA (salicylic acid) – Penetrates deep into the pores, dissolves sebum, and prevents blockages.
• Niacinamide – A versatile ingredient that evens out skin tone, strengthens the skin barrier, and reduces redness.

In addition to these modern ingredients, COSRX also integrates traditional Korean components such as:

• Snail Mucin – Deeply moisturizes, promotes skin recovery, and improves elasticity.
• Centella Asiatica (Cica) – Known for its soothing and healing properties, especially for sensitive or irritated skin.

Common to all ingredients is that they are selected for their documented effect – without compromising the skin's well-being.

Minimalist formulation

COSRX believes in "less is more". Each product contains a carefully selected few ingredients in high concentration. By eliminating fillers and potentially irritating additives like fragrance and alcohol, the risk of skin reactions is minimized.

All products are also pH-adjusted to match the skin's natural balance. This allows the skin to optimally absorb the ingredients while protecting and preserving the barrier.

Simple and clear design

The packaging is as straightforward as the formulations – COSRX has a minimalist design where every detail has a purpose. There is no excessive design here – just clear information about the product's purpose, ingredients, and usage.

The result? Skincare that does the job without confusion.

COSRX products suit all skin types and needs

COSRX offers a wide range of skincare products targeting various skin types and needs – from oily and acne-prone skin to dry or sensitive skin. All products have been developed with a focus on effective ingredients, gentle formulation, and clear function. Here are some of their most popular product categories.

Cleansing & Toner

A good skincare routine starts with a gentle yet effective cleansing – something COSRX truly masters.

• Low pH Good Morning Gel Cleanser is a customer favorite with a mild formula that cleanses the skin without disturbing its natural pH balance. It is particularly suitable for sensitive or acne-prone skin and provides a fresh start to the day without drying out the skin.

COSRX's toners are often enriched with acids or moisturizing ingredients and are perfect for balancing the skin after cleansing and preparing it for serums or creams.

COSRX's essences and serums are known for their high concentrations of active ingredients and their restorative properties.

• Advanced Snail 96 Mucin Power Essence contains a full 96% snail secretion and is developed to provide intensive hydration, improve skin elasticity, and even out skin tone. This Essence is particularly popular among users who want to counteract fine lines, redness, and acne scars.

The products in this category are often aimed at those who want more glow, improve skin texture, or work with anti-aging in a gentle yet powerful way.

Spot treatment & Exfoliation

COSRX is perhaps best known for its targeted treatments and exfoliating products.

• Acne Pimple Master Patch is one of the brand's best-selling products – small, thin hydrocolloid patches that quickly and hygienically heal inflamed pimples.
• BHA Blackhead Power Liquid is a powerful yet gentle exfoliating liquid with salicylic acid, specially designed to dissolve blackheads, counteract pimples, and improve skin texture.

These products are perfect for those who want to treat specific problem areas with precision.

Sunscreen & Moisture

Protecting the skin from the sun and keeping it hydrated are cornerstones of COSRX's philosophy.

• Aloe Soothing Sun Cream combines high sun protection with soothing aloe vera, making it ideal for daily use even on sensitive skin.
• Other popular moisturizing products include snail creams such as Advanced Snail 92 All In One Cream, known for its restorative and barrier-strengthening effect.

Regardless of the season, you will find products from COSRX that help the skin retain moisture, withstand external stresses, and feel balanced and soft.
