Product summary

"B. Kamins - NIA-Stem Moisturizer Kx" is a well-rounded moisturizing product. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Glycerin, hydrolyzed collagen, butylene glycol and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Hydrolyzed collagen, cetyl alcohol, coco-caprylate/caprate, cyclopentasiloxane and caprylyl glycol 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

  • We particularly like that there is a good concentration of niacinamide (niacinamide 3.60% - 5.50%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. 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 help improve the skin tone, reducing pigmentation marks.
  • This moisturizer includes a form of retinoids (vitamin A) - retinyl palmitate 0.10% - 0.35%, 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.
