Niacinamide
What It Is

Although the word Niacinamide may sound a little scary, it’s basically Vitamin B3, an essential nutrient for your skin. This is why Niacinamide can help your skin look healthier.

It can be found in vitamin-rich foods, such as kale, mushrooms and almonds, which help take great care of your body from the inside, as well as in our skin care products to pamper it from the outside.

What It Does

Niacinamide is a true multitasker. From boosting hydration to protecting the skin from environmental damage, it offers a wide variety of benefits. It penetrates your skin and helps renew your complexion from within.

Benefits

Although Niacinamide may be less talked about than the wonder ingredient of the decade, retinol, its benefits are just as significant. Here are some of the most amazing skin benefits of Niacinamide:

  • Increases the skin’s ability to maintain hydration. Niacinamide strengthens your skin’s moisture barrier to improve its ability to hold on to moisture. Your skin is less likely to dry out and will stay hydrated for longer. If dry skin is a concern for you, view the range here.
  • Improves skin texture. It helps reduce the size of your pores while keeping your skin moisturised.
  • Rejuvenates the eye area. The skin around your eye is extremely delicate, and this is where usually the first signs of skin ageing appear. Niacinamide can help with these skin concerns and reduce the appearance of fine lines and wrinkles for younger-looking eyes.
  • Helps with dark spots and hyperpigmentation. Niacinamide’s is a true multitasker, it can also help lighten dark spots and the marks of hyperpigmentation.
  • Aids surface skin cell regeneration for younger-looking skin. By locking in moisture, Niacinamide provides your skin with the moisture it needs for natural skin cell turnover to take place properly.
  • Helps with oily skin. Niacinamide helps regulate sebum production and this can help control oily skin.
