Product summary

"Kose - DECORTE AQ Lotion ER" has a good moisturizing formula. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Kose - DECORTE AQ Lotion ER ticks this box. Glycerin, hydrolyzed collagen and butylene 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). Hydrolyzed collagen, oryza sativa bran oil, elaeis guineensis oil, ethyl oleate and pentylene glycol 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

  • We like that this moisturizer contains peptides (palmitoyl pentapeptide-4 0.20% - 0.75%). 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.
  • Adenosine 1.50% - 2.30%. 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).
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: sodium lactate, lecithin and vitamin e
