INCI: Hirudinea Extract
Hirudinea Extract is a novel, natural ingredient with potential soothing benefits, but scientific evidence is limited and it may not be suitable for everyone due to ethical or allergy concerns.
In plain English
Hirudinea Extract comes from leeches, which are small, blood-sucking worms. In skincare, it's thought to help calm redness and keep skin hydrated, but there isn't much research yet to confirm these effects. It's a very unusual ingredient, so it's mostly found in niche or luxury products.

What it is
Hirudinea Extract is a natural extract obtained from leeches (Hirudinea species). It contains various bioactive compounds, including proteins and enzymes, that are believed to have anti-inflammatory and moisturizing properties.
How it works
In a cosmetic product, Hirudinea Extract is thought to work by providing a soothing effect on the skin, potentially reducing redness and irritation. It may also help the skin retain moisture, acting as a humectant. However, the exact mechanisms are not well-studied in cosmetic formulations.

Cons and cautions
Limited research
