The Science of Snail Mucin (and Why Ours Is Different)

By Alice Anzanello

A gentle powerhouse, ethically sourced.

At SETOSA our hero ingredient is something truly special: snail mucin or, more precisely, snail secretion filtrate. Long celebrated in skincare for its hydrating, repairing and anti-ageing properties, this natural substance offers remarkable benefits for all skin types. But not all snail mucin is created equal.

So, what exactly is snail mucin?

Snail mucin is a naturally produced substance rich in glycolic acid, allantoin, peptides, and hyaluronic acid all known for supporting skin regeneration, hydration, and elasticity.

It helps to:

  • Smooth fine lines and wrinkles;
  • Improve skin texture and tone;
  • Promote healing and barrier repair;
  • Provide long-lasting hydration.

It’s a multi-tasking active that delivers real results gently.

Why Setosa uses COSMOS-certified snail mucin

We proudly source our snail mucin through the Cherasco Method®, a patented, cruelty-free system developed by the International Institute of Cherasco in Italy. This process ensures:

  • No harm to the snails;
  • A stress-free environment for natural mucin production;
  • A highly concentrated, pure extract;
  • Full traceability and ethical integrity.

The mucin is then COSMOS-certified, meeting rigorous standards for organic and natural cosmetics in Europe. That means it's not only high-quality, it's also free from contaminants, unnecessary additives, and unethical practices.

Is it suitable for sensitive skin?

Absolutely. Our snail mucin is filtered and stabilised to retain its potency while remaining gentle enough for sensitive, reactive and post-treatment skin. Combined with our low fragrance, dermatologist-tested formulas, it works to restore calm and hydration without irritation.

A signature of softness and strength

At SETOSA, we don’t just use snail mucin. We elevate it, pairing it with ingredients like orchid stem cells, liposomal hyaluronic acid, and black pearl to create formulas that are as sophisticated as they are effective.

It’s not hype. It’s science, delivered with softness.
