What the product description says
“Formulated to target crow's feet, dark circles, and puffiness, this powerful peptide blend gets straight to work to create firmer skin.”
Source: ClearStem

This product contains caprooyl tetrapeptide-3, copper tripeptide-1, palmitoyl tripeptide-38. 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.

Caprooyl tetrapeptide-3Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.45–0.65%
Copper tripeptide-1Key activeEffect: MediumA naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.~0.3–0.6%
Palmitoyl tripeptide-38Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.4–0.6%
Lactic acidUnder-dosedEffect: MediumAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~1.5–1.9%
Camellia sinensis leaf extractEffect: Low, below effective doseCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.25–0.45%

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, isomalt.

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: caprooyl tetrapeptide-3, aloe barbadensis leaf extract.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: caprooyl tetrapeptide-3, copper tripeptide-1, palmitoyl tripeptide-38, panthenol

Product summary

Based on the ingredients included, "CLEARSTEM - BRIGHTEYES Eye Gel" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. CLEARSTEM - BRIGHTEYES Eye Gel ticks this box. Humectants in this product (panthenol, glycerin, isomalt, saccharide isomerate and sodium hyaluronate) 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). Emollients in this formulation (caprooyl tetrapeptide-3, aloe barbadensis leaf extract, caprylyl glycol and hydroxypropyl cyclodextrin) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

  • This product contains acids (lactic acid 1.50% - 1.90%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
  • We like that this moisturizer contains peptides (copper tripeptide-1 0.30% - 0.60%, caprooyl tetrapeptide-3 0.45% - 0.65% and palmitoyl tripeptide-38 0.40% - 0.60%). 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. 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.
  • Panthenol (pro-vitamin B5) at about 1.10% - 1.40% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: titanium dioxide, lecithin and lactic acid
