Product summary

"Credentials - Face Nourisher" is a well-rounded moisturizing product. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Humectants in this product (urea, cyclomethicone, glycerin, sodium hyaluronate and sodium pca) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Ceramide 3, carthamus tinctorius seed oil, cetyl dimethicone, cyclomethicone and beeswax in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

This product also contains vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this moisturizer it is used for stabilizing other ingredients in the formulation. In this concentration (0.25% - 0.50%) it cannot have a noticeable benefit for the skin.
This moisturizer includes a form of retinoids (vitamin A) - retinyl palmitate 0.25% - 0.50%, 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.
As a plus, this moisturizer also contains ceramides (ceramide 3 0.30% - 0.60%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.

Irritation risk

There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here

What can the product work for?

Anti-aging

What does the product description say?

This product contains camellia oleifera leaf extract, ubiquinone. These ingredients help neutralize free radicals in skin. By doing so, they might be able to prevent early signs of aging (like fine lines and wrinkles), at least to some extent. These ingredients will not be able to "reverse" signs of aging.

ubiquinone 0.25% - 0.5%

Irritation risk:

Concentration: Effectiveness: LOW

Coenzyme Q10. It helps neutralize free radicals in skin, improves skin hydration and might be helpful agains fine lines and wrinkles. It can be an allergen

ascorbic acid 0.25% - 0.5%

Irritation risk:

Concentration: Insufficient!

The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging

retinyl palmitate 0.25% - 0.5%

Irritation risk:

Concentration: Insufficient!

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

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: cyclomethicone, 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: beeswax, helianthus annuus seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide 3, urea

sodium pca 0.25% - 0.5%

Irritation risk:
