COSRX: An essential K-Beauty brand

Since its creation in 2013, COSRX has established itself as a benchmark in the world of Korean skincare. Inspired by traditional rituals, the brand combines natural and biotechnological ingredients to create highly effective products. But is COSRX really right for your skin? Which products are worth incorporating into your routine? Discover my opinion and my top 3 products.

⭐ My assessment is based on personal experience, supplemented by analysis of customer reviews and studies of COSRX formulations.


COSRX at a glance

The name COSRX is a combination of "cosmetics" and "prescription", underlining the brand's commitment to providing targeted solutions for skin problems. Building on its international success, the brand is renowned for its minimalist formulations, often without fragrance, alcohol or parabens.

Key ingredients such as snail mucinthe centella asiatica or thesalicylic acid are an integral part of their products, which are suitable for a wide variety of skin types, from the most sensitive to the most oily.


My opinion on three of COSRX's leading products

1. Advanced Snail 96 Mucin Power Essence

Rating: 9.5/10
This serum-essence based on 96 % snail mucin is ideal for moisturizing, regenerating and smoothing the skin.

  • Why I love it: Its light, slightly jellied texture is rapidly absorbed by the skin. It intensely moisturizes while reducing scarring and redness.
  • Its strengths: Snail mucin stimulates collagen production and accelerates healing, leaving skin firmer and more radiant.
  • My verdict: It's a must-have for dry or damaged skin, and an excellent choice for incorporating a natural anti-aging active into your routine.

2. BHA Blackhead Power Liquid

Rating: 9/10
This product is a real ally against imperfections, blackheads and dilated pores, thanks to its formulation containing salicylic acid.

  • Why it works: Its minimalist composition, enriched with humectants such as sodium hyaluronate and arginine, unclogs pores while maintaining moisture levels.
  • My experience: After a few weeks, my skin is smoother, blackheads are visibly reduced and shiny areas are matified.
  • A word of caution: It can be slightly irritating for very sensitive skin, so it's best to start gently.

3. Low pH Good Morning Gel Cleanser

  • Avis Low pH Good Morning Gel Cleanser Cosrx

Rating: 8/10
This gentle, pH-balanced cleanser is perfect for purifying the skin without disrupting its protective barrier.

  • Its strengths: It eliminates excess sebum and impurities thanks to salicylic acid and tea tree oil, while leaving the skin feeling fresh.
  • Please note: Although very effective, the presence of tea tree can irritate very sensitive skin.
  • My opinion: Ideal for combination to oily skin, this cleanser is an excellent first step in the COSRX routine.

Focus on COSRX formulations and philosophy

COSRX stands out for :

  • Streamlined formulations Fragrance-free, alcohol-free and free from harsh surfactants.
  • Natural and technological ingredients Like centella asiatica to soothe, niacinamide to brighten and snail mucin to moisturize and repair.
  • A commitment to sensitive skin The brand favors non-irritating compositions that respect the skin's balance.

However, some of their sunscreens incorporate controversial UV filters, which can be a disadvantage for reactive skin.


My final verdict on COSRX

COSRX has established itself as a must-have brand for anyone wishing to enhance their skincare routine with effective, skin-friendly and affordable products. Whether you're looking to moisturize, purify or treat specific problems, you're bound to find a COSRX product to suit your needs.

Overall rating: 8.7/10

If you're interested in exploring the world of K-Beauty, COSRX is an excellent place to start. Its products, acclaimed by millions of users, deliver visible results while respecting the skin and the planet.
