Editorial research review
A viscous essence built around 96.3% snail secretion filtrate, with humectants and soothing ingredients. It provides a hydrating, glossy layer but is not suitable for vegan users or anyone with a snail-related sensitivity.
Essences
Typically used at routine step 4.
An essence is the step most often skipped and least often explained. It is a lightweight, water-rich layer with a higher concentration of functional ingredients than a toner but less than a serum — fermented filtrates, mucin, amino acids and humectants are common. The realistic benefit is cumulative surface hydration and a smoother base for what follows, rather than a targeted correction of one concern.

HELLOCELL
Ectoin All In One Essence
A light gel essence stating 1% ectoin (10,000 ppm), with hyaluronic acid. It lists both denatured alcohol and fragrance, which sit awkwardly with ectoin's soothing reputation, so it suits resilient skin better than reactive skin.

PDRN 100 Essence
A rich, milky essence using ginseng-derived plant PDRN alongside niacinamide, ceramides, panthenol and emollients. It provides a moisturising glow and may function more like an emulsion than a water-light essence.
How the essences we hold compare
Texture, size and “best for” come from our product research. Notable ingredients are matched by exact name in each verified ingredient list: presence only, which says nothing about concentration or effect. “No Parfum listed” means the list declares no added fragrance; plant extracts and waters can still carry a scent.

How we research essences
We currently track 4 published products here. Every entry is compiled from manufacturer ingredient disclosures, published cosmetic science literature and UK retailer listings. We do not run clinical trials, and we do not publish a product until its formulation details have been checked against a source we can cite.
- Formulation: INCI lists, key actives, fragrance and alcohol status where the brand discloses them.
- Evidence: what the published research suggests for the key ingredients, and what it does not establish.
- UK availability: retailer listings and prices, with the date each was last checked. Where a price is not recent enough to quote, we say “check latest price” instead of guessing.
Results from cosmetic products are formulation-dependent and vary between people. Read our review methodology, browse the ingredient explainers or compare options in the comparison tool.
Choosing essences
- Add an essence when your routine is already stable and hydration is the gap.
- It is not a substitute for a treatment serum if you have a specific concern.
- Texture matters more than the marketing term; read what the layer actually is.
