What the product description says
“It protects the skin against photo-aging while keeping the skin hydrated.”
Source: Naos Store

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. 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. The following ingredients in this product do the job: carnosine, dextran.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: helianthus annuus seed oil, glycine soja oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-1

Product summary

"Institut Esthederm - Adaptasun Hydra-Protective Sun Water" is effective for: Moisturizing

This product could be helpful for: Anti-aging, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • Peptides (acetyl hexapeptide-1 0.20% - 0.40%). 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 (carnosine 0.10% - 0.20%, dextran 0.20% - 0.35%, carnosine 0.25% - 0.45% and glycerin 1.30% - 1.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
