“crema para el contorno de ojos”
Source: ISDIN

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: glycerin, hydrolyzed hyaluronic acid.

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: cera microcristallina, isopropyl myristate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: dipeptide-2, palmitoyl tetrapeptide-7

Product summary

"Isdinceutics - K-Ox Eyes" is effective for: Moisturizing

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

Ingredient callouts

  • This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.15% - 0.25%) it cannot have a noticeable benefit for the skin.
  • Peptides (palmitoyl tripeptide-1 0.15% - 0.25%, palmitoyl tetrapeptide-7 0.20% - 0.40% and dipeptide-2 0.20% - 0.35%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
  • Humectants (hydrolyzed hyaluronic acid 0.25% - 0.50% and glycerin 4.60% - 5.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
