“Niacinamide helps to improve the look of enlarged pores, uneven skin tone and texture, and dullness; also helps to maintain a healthy, hydrated looking complexion”

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": betaine, glycerin.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

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

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.

  • Juuj· May 2025Doesn't recommend

    It’s fine but it’s a high niacinamide percentage so it’s a little irritating

  • Mady· Apr 2025Recommends

    Great price - simple, effective, hydrating, quick absorption

  • Margoat· May 2024Recommends

    Good for brightening and soothing but you must be really careful to not mix with other products as can become irritating if ph is altered
