“As the patches work their magic, you’ll notice a brighter, more youthful appearance, thanks to the clarifying properties of papaya that help to reduce the appearance of pores.”

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.2–0.4%
NiacinamideUnder-dosedIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~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: allantoin, 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: ricinus communis seed oil.

GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~4.7–5.7%

Product summary

"KoCostar - Tropical Eye Patches Papaya" is effective for: Anti-aging

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

Ingredient callouts

  • Adenosine 0.20% - 0.40%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
  • In addition, this product contains Allantoin (1.00% - 1.30%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
  • Humectants (sodium hyaluronate 0.20% - 0.35%, allantoin 1.00% - 1.30% and glycerin 4.70% - 5.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
