Hello friends, I’m here to tell you a little skin fairy tale that's actually a true story.
It's about the first product that really transformed my skin. 
Once upon a time, there was (and still is) one of the most popular ingredients in beauty.
This star ingredient brightens and evens out your complexion, helps to reduce the appearance of pores, improves dullness, soothes and restores skin and also helps to strengthen compromised skin barriers. 
Oh, it also encourages collagen and addresses fine lines and wrinkles. 
Sounds like an overachiever, right?
The ingredient is called niacinamide. Her science-y nickname name is vitamin B3.
Niacinamide is found in a slew of different beauty products from moisturisers to serums because of its many positives for the skin. 
It also just so happens to be the hero ingredient in the first $11 serum that really transformed my skin.
Here's a hint... if you've ever Googled 'niacinamide The Ordinary NZ', you're on the right track.

The Ordinary Niacinamide Benefits.

Here are some quick facts on this skin-loving ingredient:
  • The Ordinary Niacinamide is a water-soluble vitamin that has many skin-restoring benefits (as we’ve mentioned above).
  • The Ordinary Niacinamide NZ has even been known to help with hyperpigmentation and lessening the appearance of dark spots.
  • Niacinamide is also good for those who experience redness and/or rosacea as it helps soothe irritation. 

What is The Ordinary Niacinamide NZ?

The Ordinary Niacinamide 10% + Zinc 1% - 30ml is one of the best-selling niacinamide products on Adore Beauty.
The 10% concentration of niacinamide combined with zinc has been shown to assist with skin barrier function and improve skin’s radiance over time, too. 
Zinc also has skin-conditioning, anti-inflammatory and antibacterial properties, and helps to regulate oil.
Here are some other The Ordinary niacinamide benefits and facts:
  • This serum balances sebum levels, helps with breakouts and balances oil levels (as an oily skin-haver this is what made me buy it in the first place).
  • It’s also oil-free, vegan and cruelty-free.
  • Niacinamide is most suited to oily skin or those who have congested, blemish-prone skin. 
  • Is The Ordinary’s niacinamide good for acne-prone skin? The Ordinary’s niacinamide is not a cure for acne, but can be taken along with medical acne treatments for optimal skin benefits. 
  • Can The Ordinary niacinamide cause acne? Niacinamide may cause breakouts in some skin types, but it shouldn't cause acne in the skin.

My The Ordinary Niacinamide Review.

Is The Ordinary Niacinamide 10% + Zinc 1% good? The short answer - YES.
Like most mere mortals, I have textured skin. But I used to have bumpier, rougher and much duller-looking skin.
The Ordinary Niacinamide 10% + Zinc 1% - 30ml was one of the first skincare products I ever bought.
It now has me repeating this to every person who has ever stepped into my orbit:
"The Ordinary Niacinamide is one of the first products where I saw a visible change in my skin after only a couple of weeks of using it.”
I had really dull skin for years, and had no idea that the right skincare could change this!

After a month of using The Ordinary Niacinamide 10% + Zinc 1% - 30ml I started to notice some real changes in my skin. 
My face also looked more clear and bright, and what I mean by this is my complexion looked and still looks much more even. 
My skin looked and felt less rough and bumpy, and it had really smoothed out. 
I couldn't believe all of this was happening thanks to an $11 product.
The Ordinary Niacinamide 10% + Zinc 1% - 30ml has become a mainstay in my skincare routine ever since. 
I love that it has a dropper, and it has a silky, watery texture. The texture dries down, so don't worry, you won't get any on your pillow.

I don't, and can’t, recommend one product to everyone because everyone has different skin types and concerns. 
But The Ordinary niacinamide is an exception. 
In fact, a friend of mine who I recommended The Ordinary Niacinamide 10% + Zinc 1% - 30ml to said that after a few months of using it, she met up with some friends who complimented her on how good her skin was looking. 
I was expecting a bouquet of flowers the next day.

Niacinamide is an ingredient that is great for overall skin health, so it can easily slot into any skincare routine.
You can layer and mix The Ordinary niacinamide serum with most skincare products and ingredients, with the exception of vitamin C (unless the ingredients are specifically formulated together).
If you're looking for The Ordinary niacinamide skincare routine help, here's how I like to use it in my regimen.
In the morning, I pop my vitamin C on with my sunscreen for double antioxidant protection.
I prefer to keep niacinamide for the PM. I lightly smooth the serum over my face after cleansing, gently patting it into my skin while it's still a little damp. I then follow up with any moisturisers or face oils.
