Ingredient callouts
- A good concentration of Niacinamide (1.90% - 2.90%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- Humectants (arginine 0.15% - 0.60%, betaine 2.70% - 4.00% and glycerin 4.10% - 6.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Promise: Evens skin tone
What does the product description say?
Formulated with 65% rice extract, this sleeping mask intensely hydrates and brightens skin to give you a fresh and even complexion.
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| niacinamide | HIGH | | |
Promise: Moisturizing
What does the product description say?
Can also be used as a moisturizing cream.
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:
arginine, betaine.
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: arginine, dimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| betaine | HIGH | | |
| glycerin | HIGH | | |
| helianthus annuus seed oil | HIGH | | |
Other benefit: Anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
| Ingredient | Effectiveness | Concentration | Irritancy |
|---|---|---|---|
| niacinamide | HIGH | | |
