Ingredient callouts
- this product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.10% - 0.40%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
- Peptides (dipeptide diaminobutyroyl benzylamide diacetate 0.95% - 1.45% and caprooyl tetrapeptide-3 0.10% - 0.45%). 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.
- Panthenol (pro-vitamin B5) at about 1.20% - 1.70% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
- Humectants (panthenol 1.20% - 1.70%, glycerin 4.00% - 6.00% and dextran 0.30% - 0.70%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

What does the product description say?

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:
dextran, 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: helianthus annuus seed oil, caprylyl glycol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: caprooyl tetrapeptide-3, dipeptide diaminobutyroyl benzylamide diacetate, panthenol
Helps attract water to the upper layer of the skin and can help improve skin barrier function
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
Helps attract water to the most upper layer of the skin. Derived from sugar

One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function
Helps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating
Helps attract water to the upper layer of the skin and improves the product texture
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Helps preserve products and creates a nice product texture
An 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)
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself

This product contains caprooyl tetrapeptide-3, dipeptide diaminobutyroyl benzylamide diacetate. 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.

Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect
