“What it is: A spray-on vegan collagen and probiotic serum that hydrates, soothes, and visibly firms, lifts, and plumps.”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": erythritol, glycerin.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tripeptide-37
Anti-agingPalmitoyl tripeptide-37May help
“What it is: A spray-on vegan collagen and probiotic serum that hydrates, soothes, and visibly firms, lifts, and plumps.”
This product contains palmitoyl tripeptide-37. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Ingredient callouts
- Peptides (palmitoyl tripeptide-37 0.05% - 0.25%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. They might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
- Humectants (sodium hyaluronate 0.05% - 0.25%, glycine 0.10% - 0.45%, lactobacillus ferment 0.20% - 0.70%, erythritol 0.35% - 0.85% and glycerin 2.60% - 3.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
