Product details

COSRX Snail Mucin 96% Repairing Serum is a lightweight, fast-absorbing essence formulated with over 96% snail secretion filtrate to hydrate, calm, and visibly refresh dull or dehydrated skin.

This Korean skincare serum centers on a high concentration of snail secretion filtrate (often called snail mucin) to support moisture retention and skin resilience. The clear, gel-like formula sinks in quickly, layering easily under creams or makeup and delivering lasting softness without greasiness. Designed for daily use, it aims to improve skin texture and comfort while remaining simple enough for sensitive routines.

How does this serum add moisture without feeling heavy?

The COSRX Snail Mucin essence uses a mucin-rich filtrate that binds water to the skin and spreads thinly for even coverage. Its lightweight consistency keeps pores clear and lets subsequent products absorb more effectively.

  • 96.3% snail secretion filtrate for strong humectant action
  • Gel texture that absorbs quickly and layers easily
  • Non-greasy finish suitable for morning or night routines
  • Works under sunscreen and makeup without pilling

Will this help improve the look of dull or uneven skin?

The formula targets dullness by delivering moisture and calming ingredients that support healthier-looking skin surface over time. Regular application can help skin appear smoother and more luminous as hydration levels normalize.

  • Helps restore softness and plumpness for a more even appearance
  • Soothes dehydrated, stressed skin to reduce rough patches
  • Compatible with exfoliants and brightening serums in a routine
  • Gentle enough for repeat use, encouraging consistent results

Is the snail mucin ethically sourced and suitable for sensitive skin?

COSRX states the snail secretion is collected in a snail-friendly way and processed for cosmetic use without harming the animals. The product has passed dermatological testing and human repeat insult patch tests, but a quick patch test is recommended for new users.

  • Snail secretion filtrate collected without harming snails
  • Hypoallergenic and dermatologist-tested formulation
  • Patch test advised—wait 24 hours before full-face use
  • Consult a physician if you experience irritation

How should I add this essence to my skincare routine?

Apply the serum after cleansing and toning, while skin is slightly damp to lock in hydration. Use a few drops across face and neck, then follow with moisturizer and sunscreen in the morning or a richer cream at night.

  • Apply 1–2 pumps to damp skin for best absorption
  • Layer under moisturizer; safe to combine with most actives
  • Use daily—morning and/or evening—for continuous hydration
  • Store away from direct sunlight to preserve efficacy

Who is this for: This COSRX Snail Mucin 96% Repairing Serum is suited for anyone with dry, dehydrated, or texture-prone skin seeking a lightweight hydrator that supports smoother-looking skin. It’s also a good choice for those who follow multi-step Korean routines, people who prefer gentle, science-backed cosmetic actives, and users looking for a non-greasy essence to layer beneath treatments and moisturizers. If you have known allergies to snail-derived ingredients, consult a professional before use.
