Ingredient callouts
- this product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.20% - 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.
- Humectants (soluble collagen 0.25% - 0.45%, sodium hyaluronate 0.25% - 0.45%, panthenol 0.35% - 0.65%, glycerin 4.60% - 5.60% and biosaccharide gum-1 0.25% - 0.45%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Moisturizing
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:
biosaccharide gum-1, 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, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
A great emollient that can also have anti-oxidant properties
Red algae extract that helps attract water to the upper layer of the skin
Helps attract water to the upper layer of the skin and can help improve skin barrier function
Almond extract (oil) - helps soften the upper layer of the skin
Sugar extract that helps attract water to the upper layer of the skin

A typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin
An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.
Helps attract water to the upper layer of the skin and is claimed to provide a longer-lasting hydration because of its ability to create a water-binding film on the surface of the skin

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

Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)

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
