“Oui Essential Hydrating Facial Serum”
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: borago officinalis seed oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: dipeptide diaminobutyroyl benzylamide diacetate
Anti-agingDipeptide diaminobutyroyl benzylamide diacetateMay help
“A balance of Vitamins and Anti-Oxidants work to protect the skin against exposure to environmental damage and aggressors, whilst also hydrating the skin and improving its visible firmness.”
This product contains dipeptide diaminobutyroyl benzylamide diacetate. This ingredient 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.
Anti-blemishAllantoinNot delivered
“Infused with Aloe Vera, popular for its anti-inflammatory properties, the serum helps to soothe dry, irritated and blemished skin.”

Ingredient callouts
- Peptides (dipeptide diaminobutyroyl benzylamide diacetate 0.45% - 1.05%). 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. They 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.
- In addition, this product contains Allantoin (1.50% - 2.30%). 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 0.55% - 1.30%, allantoin 1.50% - 2.30% and glycerin 4.40% - 6.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
