How much niacinamide does it contain?

The niacinamide percentage is not listed for this US SPF 30 formula. Niacinamide appears among the inactive ingredients, alongside glycerin, dimethicone and ceramide 3. The sunscreen active ingredients are avobenzone, homosalate, octisalate and octocrylene; niacinamide is not one of the sunscreen filters.1

What does niacinamide add to a moisturizer?

Niacinamide is a form of vitamin B3. As general ingredient guidance, it may support the skin barrier, the protective layer that helps retain moisture and keep irritants out. It can also help calm inflammation and redness. Those are reasons to consider niacinamide in a routine, not a timetable for results from this particular moisturizer.2

Niacinamide is not the only moisturizing ingredient worth noticing. Ceramides help strengthen the skin barrier, while glycerin helps smooth and soften skin. Choosing a moisturizer means considering the formula, rather than shopping for one ingredient in isolation.3

How do you use the SPF 30 version?

The UV SPF 30 version is a sunscreen as well as a moisturizer, so the long product name is at least doing some work. Use its sunscreen directions for daytime sun protection.1

  1. 1Shake well before applying.
  2. 2Apply liberally 15 minutes before sun exposure.
  3. 3Reapply at least every 2 hours.
  4. 4Use a water resistant sunscreen if you will be swimming or sweating.

Also limit sun exposure, especially from 10 a.m. to 2 p.m., and use protective clothing, a hat and sunglasses. Keep the product out of your eyes and rinse with water if it gets into them. Do not apply it to damaged or broken skin.1

What if you have sensitive skin?

Niacinamide is generally gentle, but it can rarely cause itching, redness, mild burning or an allergic reaction. If you are concerned, test a small amount on your forearm and wait 24 hours. Check your other products for niacinamide too, and avoid using too many products containing it at once.2

For the UV SPF 30 moisturizer, stop use and ask a doctor if a rash occurs.1
