Snail mucin: what it does and who should skip it

Snail secretion filtrate is mostly glycoproteins, hyaluronic acid and glycolic acid in trace amounts. It hydrates and helps repair - it is not a miracle.

What it actually does

In small studies and a lot of dermatology practice, mucin improves hydration and speeds up barrier recovery after irritation. The glycoproteins hold water; the trace glycolic acid gently softens the surface.

What it does not do

It will not fade pigmentation, remove scarring or replace sunscreen. If a brand promises those, it is selling the story rather than the ingredient.

Texture and layering

Essences are slippery and slightly tacky. Apply after toner, before cream, on damp skin. Give it a minute before the next layer or the cream will slide.

Who should skip it

• Anyone with a dust-mite or shellfish allergy - patch test first.
• Skin that reacts to proteins in general.
• People who dislike a tacky finish: use it at night only.
