COSRX

COSRX is more than just a creative name: it's a statement of intent. Cosmetics + Prescription, cosmetics as a precision tool, not a pastime. Founded on December 16, 2013 by Jeon Sanghoon, COSRX has become one of the most recognizable K-Beauty brands in the world within a few years, with distribution in 146 countries and over 135 international awards.

The philosophy is simple: active ingredients, minimalist formulas, visible results. No product exists to complete a line; it exists because it solves a specific problem. This dermatologist-like mindset has won over both the skincare community and industry professionals.

Since 2023, COSRX has been a subsidiary of Amorepacific, the largest Korean cosmetic group, while maintaining its unique formulation identity and "functional first" positioning.

Founded in 2013 by Jeon Sanghoon in Seoul, COSRX (Cosmetics + Prescription) is now distributed in 146 countries and has won over 135 international awards. Since 2023, it has been a subsidiary of Amorepacific.

The motto "Expecting Tomorrow" reflects the brand's scientific approach: each product is developed with long-term results in mind, not immediate effects

COSRX works with highly concentrated functional ingredients in deliberately simple formulas. There are no trendy ingredients included to appear innovative: every active ingredient has a precise, documented, measurable role.

The approach is clinical: identify the skin problem, select the most effective active ingredient, formulate it at the optimal concentration. This has made COSRX the go-to brand for those who want serious skincare, without excess.

  • Snail Mucin (80-92%): COSRX's signature active ingredient. Promotes cell regeneration, moisturizes, smooths imperfections, and supports the skin barrier. The real concentrations (not traces) distinguish COSRX from those who use mucin as a secondary ingredient.
  • Black Bee Propolis (Full Fit): Extracted from bees that work with wild flora, it has antioxidant, antibacterial, and regenerating action. The Full Fit line uses premium concentrations.
  • BHA (salicylic acid): A fat-soluble chemical exfoliant that penetrates pores and dissolves oxidized sebum. Ideal for acne-prone skin, enlarged pores, and blackheads.
  • CICA-7 Complex (patented): Seven Centella Asiatica derivatives that act synergistically to soothe, regenerate, and protect the barrier. One of the most advanced formulas for reactive skin.
  • Galactomyces Ferment Filtrate: Derived from yeast fermentation, with brightening, evening, and plumping action. Comparable to SK-II's Pitera but in accessible formulas.
  • Niacinamide: Regulates sebum, reduces visible pores, evens skin tone, strengthens the barrier. Present in various COSRX formulas.
  • Vitamin C 19% waterless (Pure Fit): An anhydrous formula to maximize the stability and effectiveness of pure L-Ascorbic Acid.
  • Acne-prone skin: BHA, snail mucin, and propolis to treat active breakouts, prevent recurrence, and reduce post-acne marks
  • Dry skin and compromised barrier: 92% mucin and CICA-7 Complex to restore hydration and protective function
  • Sensitive and reactive skin: CICA-7 Complex and formulas without irritating ingredients
  • Enlarged pores and oily skin: BHA and niacinamide to regulate sebum and minimize pores
  • Uneven tone and dark spots: Galactomyces, niacinamide, and vitamin C to even out and brighten

COSRX is the brand that proves K-Beauty is not just about aesthetics: it's chemistry applied to the skin, done well. The mucin concentrations indicated on the label are real. Patents such as CICA-7 Complex are documented. The 135 international awards are not self-certifications.

For us, it is a pillar of our selection because it embodies the AurynSkin mentality: verified ingredients, clean formulas, demonstrable results

  • How is COSRX snail mucin collected? COSRX uses an ethical harvesting process where snails move freely over a mesh surface and naturally release their secretion. No chemical or electrical stimulation is used. The mucin is then filtered and concentrated
  • Is COSRX BHA suitable for those new to chemical exfoliants? Yes. The salicylic acid concentration in COSRX products is designed to be effective yet tolerable even for beginners. It is recommended to start with alternate-day applications and always use sun protection during the day
  • What distinguishes the CICA-7 Complex from other centella products? The CICA-7 Complex is a COSRX patent that combines seven distinct derivatives of Centella Asiatica (asiaticoside, asiatic acid, madecassoside, madecassic acid, and others). This synergy amplifies the soothing and regenerating effect compared to using centella in a single form
  • Is COSRX cruelty-free? Yes, COSRX is cruelty-free and does not sell in markets that require animal testing. Since 2023, it has been part of Amorepacific, which also has formal commitments regarding cruelty-free practices
