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: dextran, glycerin.

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: caprylic/capric triglyceride, helianthus annuus seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl octapeptide-3, caprooyl tetrapeptide-3, dipeptide-2, palmitoyl tetrapeptide-7, palmitoyl tripeptide-38

Acetyl octapeptide-3Hero· HumectantEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.2–0.4%

Source: Lookfantastic US

This product contains acetyl octapeptide-3, caprooyl tetrapeptide-3, dipeptide-2, palmitoyl tetrapeptide-7, palmitoyl tripeptide-38, tocotrienols. These ingredients 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.

Retinyl palmitateUnder-dosedEffect: MediumThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.2–0.4%

Product summary

"CosMedix - Eye Genius Brilliant Eye Complex" has a good moisturizing formula. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. CosMedix - Eye Genius Brilliant Eye Complex ticks this box. Acetyl octapeptide-3, dextran, glycerin, sodium hyaluronate and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Caprooyl tetrapeptide-3, palmitoyl tetrapeptide-7, beta-sitosterol, borago officinalis seed oil and caprylic/capric triglyceride 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 includes a form of retinoids (vitamin A) - retinyl palmitate 0.20% - 0.40%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • We like that this moisturizer contains peptides (palmitoyl tripeptide-38 0.20% - 0.40%, palmitoyl tetrapeptide-7 0.25% - 0.45%, acetyl octapeptide-3 0.20% - 0.40%, dipeptide-2 0.20% - 0.40% and caprooyl tetrapeptide-3 0.25% - 0.50%). There are many different kind of peptides and they are naturally present in our skin. They all are a combination of amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, but it is very likely that they have a benefit. Peptides 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.
