Based on the ingredients included, "Ren Skincare - REN Keep Young Beautfiul Firm Lift Eye Cream" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Ren Skincare - REN Keep Young Beautfiul Firm Lift Eye Cream ticks this box. Glycerin and glucose 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). Emollients in this formulation (camellia oleifera seed oil, caprylic/capric triglyceride, helianthus annuus seed oil, squalane and cetearyl alcohol) 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
We like that this moisturizer contains peptides (hexapeptide-11 0.35% - 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.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: rosehip oil, vitamin e and myristyl myristate

What does the product description say?
Hydroxyproline from Aminoacids Lipovector plumps the skin .
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, glucose.
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: hexapeptide-11
Oil of a very fragrant pink rose used as fragrance in cosmetics. Extensive research has shown it has mixed benefits.
