Vitamin B Family 

Vitamin B is huge, it has eight different types of B vitamins! These all come from various sources and have a variety of skincare benefits. What you really need to know are the 3 primary forms: vitamin B3, vitamin B5 and vitamin B12.

Vitamin B3 – reduces dark spots and boosts collagen production. It has a derivative of niacinamide that helps to retain moisture.

Vitamin B5 – a humectant found in moisturizers, shampoos and hair conditioners that offer the condition of a barrier to the skin 

Vitamin B12 – an important vitamin to get from diet or supplements but if applied to the skin, it treats eczema too

What is Vitamin B3?

Vitamin B3 is the most common and go-to active ingredient. It has three branches, niacin, niacinamide and nicotinamide. Niacin is mainly found in food and supplements, while niacinamide and nicotinamide are found in skincare products.

Niacinamide is most commonly found in skincare products like serums, moisturisers or masks. So what exactly is Niacinamide?

Vitamin B3 or Niacinamide is one of the most stable active ingredients unlike AHAs, BHAs, Retinol and Vitamin C. The pH level of niacinamide is neutral, which means it is non-irritating and non-acidic, making it suitable for all skin types.

Niacinamide is a water-soluble vitamin that won’t dissolve in oil. It’s easily absorbed by the outer layer of the skin which then helps to keep the acid mantle healthy! 

With niacinamide, it will help your skin feel softer and more radiant without irritations like other chemicals cause.

What are the benefits of Niacinamide or Vitamin B3?

Niacinamide has multiple benefits for improving the skin’s barrier, reducing fine lines, decreasing redness and improving the skin’s elasticity. Niacinamide offers almost everything that we want for our skincare plus more! 

Let’s break down these benefits and how niacinamide works for every skincare concern.

Niacinamide Helps with Dryness as well as Anti-ageing 

Niacinamide plays a big part in the hydration level and moisturisation of the skin. Hydration and moisture also play a role in ageing.

The skin barrier needs to be well-nourished and moisturised because it produces ceramides, fatty acids, key proteins, and lipids. These occurring ingredients help the skin maintain its plump and healthy glow. 

Niacinamide basically keeps the skin barrier nourished and helps with growing more ceramides to properly retain moisture. As the skin barrier is nourished, it becomes thicker and stronger and is able to protect the skin from bacteria and free radicals.

As we age, the transepidermal water loss or TWEL slows down, which leads to sagging and dull skin. Niacinamide dramatically helps with reducing the evaporation of water from the skin. With that, it then increases the moisture levels of the skin to strengthen and thicken the skin barrier further.

Furthermore, niacinamide also helps to increase collagen production, which makes it really good for stopping ageing.

Niacinamide Controls Acne and Minimizes Pores

Since niacinamide has anti-inflammatory and anti-microbial properties, it helps significantly with alleviating and controlling mild to moderate acne. It also helps with reducing and controlling the amount of sebum that is secreted from the pores.

When our pores are clogged with excess sebum and dead skin, it makes the pores more prominent. Niacinamide helps to regulate sebum production, which ultimately helps to minimize the size of the pores. This will give your skin a smoother texture.

Niacinamide Brightens Skin and Reduces Hyperpigmentation 

For hyperpigmentation, niacinamide helps with disrupting one of the key enzymes that produce melanin. Melanin is a pigment that our body produces which gives colour to our skin, hair and eyes. But the downside of melanin is that it’s also produced by the skin in response to skin damage by the harsh UV rays. That’s why it’s essential to wear sunscreen! 

Niacinamide stimulates the production of keratin to prevent further melanin production. This thickens the outer layer of the skin and helps to remove dark spots that acne marks left. 

Niacinamide Reduces Redness

Niacinamide is excellent for reducing redness. It’s even more significant for people who suffer from rosacea. It’s been said in studies that niacinamide helps alleviate the redness and keep the skin’s barrier healthy. 

Niacinamide Fights Off Free Radicals

Free radicals are apparent in the air and environment. These get into our skin and cause stress, also making the skin age prematurely. Just like Vitamin C, Niacinamide is also a huge factor when it comes to fighting off these free radicals.

How To Use Niacinamide in Skincare

These benefits are just incredible and while some vitamins have an adjustment period, niacinamide doesn’t and it has almost little to no side effects. Plus, you can use high percentages of it, and your skin will still respond well.

Since it is one of the most stable ingredients in skincare, it works well with other ingredients too. You don’t have to worry about mixing the wrong ingredients with niacinamide because it is not irritating and won’t cause any breakouts. 

For better results, leave-on niacinamide products are recommended. After cleansing, you should follow it up with a toner that has niacinamide in to really get the ingredient into your skin.

If you have skincare concerns such as sun damage, texture and big pores, you can use a concentration of up to 20% in niacinamide serum. You can experiment with concentration to see what works best for you.

Niacinamide-infused products are also safe around the eyes and using it in eye cream can help with dark circles and diminish the appearance of crow’s feet.

Adding niacinamide to your skincare regimen is truly a no-brainer. It offers versatility with benefits that will improve your skin’s health and make it radiant and look younger.

My Thoughts

Vitamin B3 is a remarkable ingredient that you should be adding to your skincare routine. Not only is it easy to work with, but any skin type can reap the benefits of vitamin B3 or Niacinamide!

Just like I said in the beginning, knowing and learning more about ingredients will make you a well-informed consumer. We need to know the benefits of ingredients and what effects they have on our skin, the more informed we are, the higher the chance of us understanding our skin properly!
