This product could be helpful for: Evens skin tone and Anti-aging, but its actives are not the most effective or are not well-studied.
Ingredient callouts
- this product includes a form of Retinoids (vitamin A) - retinyl palmitate 2.10% - 2.50%, 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.
- Ceramides (ceramide 1 0.35% - 0.65%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
- Humectants (polyglutamic acid 0.75% - 1.10%, sodium hyaluronate 1.00% - 1.30% and trehalose 8.00% - 9.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Moisturizing
What does the product description say?
Contains Nobel Prize Winning Ingredient Fullerene , clinically proven to reduce wrinkles & protect skin against UV damage.
Source: N/A
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:
polyglutamic acid, sodium hyaluronate.
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: ceramide 1, glyceryl polymethacrylate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide 1

Anti-aging
What does the product description say?

Source: N/A
This product contains retinyl palmitate. 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.
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
