Ingredient callouts
Peptides (acetyl dipeptide-1 cetyl ester 0.05% - 0.20%). 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 0.45% - 1.05%, glycerin 3.70% - 5.60% and betaine 2.80% - 4.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Price
The product retails from 47.60A$ up to 61.50A$ in Australia, from 28.00$ up to 59.40$ in the United States, from 21.75£ up to 29.00£ in the United Kingdom and for 39.50CA$ in Canada.
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called
"humectants":
betaine, 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).
