Snail mucin and skincare terms, explained in plain English
Skincare and science jargon, decoded. You'll also see these definitions when you hover over or tap underlined terms in our guides.
- Allantoin
- A soothing, skin-softening compound found in snail mucin and comfrey, and widely used in sensitive-skin products.
- Comedogenic
- Likely to clog pores and cause blackheads or whiteheads. Non-comedogenic products are less likely to do so.
- Essence
- A thin, watery Korean-style skincare step applied after toner and before serums or moisturizer. Many snail mucin products are essences.
- Fibroblasts
- Cells deep in the skin that make collagen and elastin, the proteins that keep skin firm and springy.
- Glycosaminoglycans
- Long sugar molecules that bind lots of water. Hyaluronic acid is the best-known one, and snail mucin contains several.
- Heliciculture
- Snail farming, traditionally for escargot and now also for collecting snail mucin.
- Humectant
- An ingredient that attracts and holds water, like hyaluronic acid or glycerin. Humectants work best on damp skin and sealed in with moisturizer.
- Lab (in vitro) study
- Research done on cells or tissue in a dish rather than in living people. Useful for understanding how something might work, but not proof it works on your face.
- Mucin
- A large, sugar-coated protein that makes mucus slippery and stretchy. Snail mucin is named after these proteins.
- Occlusive
- A rich ingredient, like petrolatum or shea butter, that forms a seal on the skin to stop water escaping.
- Patch test
- Trying a new product on a small area, such as the inner arm, for 7 to 10 days to check for a reaction before using it on your face.
- Phyto-mucin
- A plant-based alternative to snail mucin, usually made from plant gums and humectants to mimic its stretchy texture and hydration.
- Purging
- A temporary breakout caused by ingredients that speed up skin cell turnover, like retinoids and acids. Snail mucin does not cause purging.
- Randomized controlled trial
- A study where people are randomly given either the real treatment or a placebo, which makes it the strongest type of evidence for whether something works.
- Retinoid
- The family of vitamin A ingredients, including retinol, retinal, adapalene and prescription tretinoin. The best-studied topical ingredients for wrinkles and acne.
- Skin barrier
- The outermost layer of skin, made of cells and fats, that keeps water in and irritants out. A damaged barrier feels tight, stings and looks flaky or red.
- Snail secretion filtrate
- The official ingredient-label name for purified snail mucin: snail slime that has been filtered and cleaned for use in cosmetics.
- Transepidermal water loss (TEWL)
- The water that evaporates from your body through your skin. Lower TEWL means your skin barrier is holding moisture in better.
