“Bronz Repair Protective Anti-Wrinkle and Firming Face Care Strong Sun”
From product name

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: artemia extract, aspartic 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: beeswax, cera alba.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-1, palmitoyl tetrapeptide-7

Acetyl hexapeptide-1HeroEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.1–0.2%

Product summary

Based on the ingredients included, "Institut Esthederm - Bronz Repair Protective Anti-Wrinkle and Firming Face Care Strong Sun" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Institut Esthederm - Bronz Repair Protective Anti-Wrinkle and Firming Face Care Strong Sun ticks this box. Humectants in this product (artemia extract, aspartic acid, carnosine, dextran and glycerin) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Palmitoyl tetrapeptide-7, oryza sativa bran oil, beeswax, cera alba and helianthus annuus seed oil in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • This moisturizer also contains Peptides (acetyl hexapeptide-1 0.10% - 0.20% and palmitoyl tetrapeptide-7 0.20% - 0.40%). 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 they are 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.
  • Actives derived from an extract of the Centella Asiatica plant (also known as Gotu Kola) - asiatic acid 0.25% - 0.45%, madecassic acid 0.25% - 0.45% and asiaticoside 0.20% - 0.40% The Centella Asiatica Actives help strengthen and restore the skin barrier, decrease inflammation in skin and neutralize free radicals. They also can help to reduce scarring. The good news is that these actives work even in low concentrations.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: vitamin e and copper gluconate
