Snail Egg Extract
The extract coming from the eggs of the garden snail, or Cornu aspersum. When it comes to snails and cosmetics, the snail slime is a pretty common ingredient that does have nice repair and hydration properties. As for the eggs extract, a study from 2015 examined it in vitro (in the lab, not on real people!) and found promising skin regenerative properties.
More specifically, snail eggs extract seem to promote the production of extracellular matrix components (fibronectin, collagen 1 and MMPs) and it also seems to improve the cell survival after UVB irradiation. The results from the study are promising but do not forget that it's in-vitro so it may or may not apply when we slather snail eggs extract on our face.
